The Epson EcoTank ET-8550 is the strongest general-purpose choice for thick paper and heavyweight cardstock because Epson documents a rear-feed path for 0.61–1.3 mm media, loaded one sheet at a time. The ET-8550 also combines six-color photo printing with wide-format support, although its price, size, and slow single-sheet workflow make it unsuitable for high-volume production.
Choosing an inkjet printer for cardstock is not as simple as finding the words “card stock” in a specification sheet. A printer may accept light index cards but reject heavy cover stock, require a rear manual feed, or produce smears on coated paper even when the sheet feeds successfully.
Key takeaways
- The Epson EcoTank ET-8550 officially supports 0.61–1.3 mm thick paper or cardstock through its rear paper-feed slot, one sheet at a time.
- The HP OfficeJet Pro 9730e lists support up to 250 g/m2 or 66 lb bond, but its recommended media range is only 16–28 lb bond, so it is better for office work than very heavy craft stock.
- GSM measures paper mass, not physical thickness, and “110 lb” is incomplete unless the rating is identified as bond, cover, or index.
- A rear, manual, or straight-through feed is generally more useful for thick media than a standard cassette because the sheet encounters fewer sharp bends.
- Successful cardstock printing depends on surface coating, stiffness, curl, drying, and ink adhesion as well as the printer’s stated weight or thickness limit.
Which inkjet printer is best for thick paper and heavyweight cardstock printing?
The Epson EcoTank ET-8550 is the best all-around inkjet printer for thick paper and heavyweight cardstock printing when photo quality, creative media, and occasional wide-format work matter more than speed. Epson specifically directs users to place 0.61–1.3 mm thick paper or cardstock in the rear feed slot, one sheet at a time, according to its ET-8500/ET-8550 thick-paper instructions.

Its six-color ink system is aimed more at images and illustrations than ordinary four-color office printing, and its wide-format capability accommodates larger creative projects. An August 16, 2026 update to TechRadar’s all-in-one printer coverage also identifies the ET-8550 as producing strong photo output on cardstock-sized work, but testing evidence should be kept separate from Epson’s official media limit.

The ET-8550 is not a fast production cardstock printer. One-sheet feeding limits throughput, the printer occupies substantial desk space, and a nominal thickness range does not guarantee reliable results with every laminated, textured, coated, warped, or unusually rigid sheet.
Best thick-paper inkjet printers compared
The following comparison separates genuine thick-media capability from broader office or craft usefulness. “Maximum documented media” is not the same as a recommended everyday range, and the figures apply only to the cited model, media category, and feed path.
| Printer | Best for | Documented media information | Feed and size strengths | Ink and workflow | Main limitation |
|---|---|---|---|---|---|
| Epson EcoTank ET-8550 | Thick cardstock, photos, invitations, and art | 0.61–1.3 mm thick paper or cardstock | Rear slot; one sheet at a time; wide-format support | Six-color tank system; strong photo focus; borderless creative work | High purchase price, large footprint, and slow single-sheet feeding |
| HP OfficeJet Pro 9730e | Wide-format office documents and moderate-weight stock | Up to 250 g/m2 or 66 lb bond listed as supported; recommended range 16–28 lb bond | Up to 11 × 17 inches; two trays; office-oriented handling | Cartridge office ink; scanning, copying, and duplex features | Do not treat the maximum as a promise of reliable 300-gsm craft printing; U.S. store availability was shown as unavailable on August 18, 2026 |
| Canon PIXMA TS9521C | Craft projects and mixed creative media | Canon emphasizes media categories and craft functions; public support material is not a simple universal gsm limit | Rear tray; greeting cards, labels, square media, and borderless or duplex projects | Consumer photo/craft workflow; automatic duplex and borderless printing | Stock limits vary by media category; verify the exact paper before buying heavy cardstock |
| Brother wide-format MFC-J series | Office documents, scanning, copying, and occasional cardstock | Model-specific; some Brother documentation lists index-card media at 120 g/m2 and 0.15 mm, while other models and specialty media differ | Wide-format business features vary by model; some include manual or specialty paths | Office-first inkjet workflow; tank or cartridge details vary by model | Do not assume one Brother model’s media limit applies to another |
| Canon imagePROGRAF PRO-series | Professional photographs and fine-art work | Canon media guides list professional papers around 300 gsm for compatible printer families and media types | Professional photo-media handling; exact sizes and paths depend on model | Pigment-ink, color-managed photo workflow | Expensive and specialized; generally lacks the convenience of an office all-in-one |
Which printer should you buy for your specific cardstock project?
The best printer depends on the stock, size, finish, run length, and need for office functions. A printer that is excellent for one-sheet art prints may be a poor choice for a stack of folded invitations.
| Your priority | Best starting point | Why | What to verify first |
|---|---|---|---|
| Thick creative stock and high-quality photos | Epson EcoTank ET-8550 | Explicit 0.61–1.3 mm rear-feed guidance and six-color photo printing | Actual sheet thickness, finish, size, and one-sheet workflow |
| Tabloid office documents and occasional heavier paper | HP OfficeJet Pro 9730e or a comparable Brother wide-format MFC | Scanning, copying, duplex documents, and wide-format support | Recommended—not merely maximum—media range and current availability |
| Craft templates, labels, greeting cards, and varied media | Canon PIXMA TS9521C | Craft-focused media handling, borderless printing, and automatic duplex | Canon’s exact limitation for the chosen third-party or specialty stock |
| Archival photographs or fine-art prints | Canon imagePROGRAF PRO-series or a comparable professional photo printer | Pigment ink and more advanced color-management options | Approved media guide, printer footprint, ink cost, and print-only design |
| Hundreds or thousands of cards | Production printer or commercial print service | Manual one-sheet feeding on many consumer models is too slow for large batches | Per-piece cost, finishing, turnaround, and proofing requirements |
What is the difference between gsm, lb bond, lb cover, lb index, and thickness?
GSM, pounds, points, mil, and microns describe different properties or rating systems, so the same numerical value cannot be compared without its unit and category.
- GSM or g/m2 means grams per square meter. GSM is widely used outside the United States and describes paper mass.
- lb bond describes office paper. A numerical bond rating should not be treated as the equivalent of the same numerical cover rating.
- lb cover describes heavier cardstock commonly used for covers, invitations, and cards.
- lb index is another U.S. paper-weight category and does not equal the same number in bond or cover.
- Points, mil, and microns describe physical caliper or thickness. A point is commonly used as a thickness unit in paper specifications; printer manuals may instead state millimeters or inches.
A label such as “110 lb cardstock” is incomplete. The buyer must determine whether the manufacturer means 110 lb bond, 110 lb cover, or 110 lb index. A 110 lb cover sheet is materially different from 110 lb bond paper.
Approximate cardstock weight guide
The ranges below are practical categories rather than universal conversions. GSM is not thickness: two papers with the same GSM can have different calipers because of coating, fiber density, manufacturing, and construction.
| Common description | Approximate GSM range | Typical printing implication |
|---|---|---|
| Light cardstock | 160–200 gsm | Often manageable through a suitable rear tray, depending on stiffness and finish |
| Medium cardstock | 200–250 gsm | Usually requires a printer with a documented rear or manual media path |
| Heavy cardstock | 250–300 gsm | Highly model-specific and often limited to one-sheet feeding |
| Very heavy stock | 300+ gsm | May require a specialist photo printer, straight path, or commercial equipment |
Why does rear feeding matter for thick paper?
Rear or manual feeding generally reduces the sharp bends required by a standard paper cassette, making the rear path the preferred route for thick or rigid sheets when the manufacturer specifies it. The Epson ET-8550’s instructions are a clear example: 0.61–1.3 mm media belongs in the rear paper-feed slot, one sheet at a time.
Useful thick-media hardware includes a rear specialty slot, manual feed, a straight-through path, adjustable guides, a rear exit tray, specialty-media presets, borderless support, and a way to disable automatic duplexing. These features do not override the manufacturer’s media table, but they make successful feeding more likely.
One-sheet feeding is an important trade-off. One-sheet feeding can reduce jams and path stress for invitations or art prints, but one-sheet feeding makes a consumer printer unsuitable for fast production runs of hundreds of cards.

How do ink type and paper coating affect cardstock results?
Ink type and surface finish affect color, drying, permanence, and adhesion after the sheet has passed through the printer.
Dye-based ink
Dye-based ink often produces vivid color and attractive glossy photographs. Depending on the formulation and paper, dye ink can be more vulnerable to water or fading than pigment ink.

Pigment ink is generally preferred for long-term document stability and fine-art work. Pigment ink does not automatically look better on every glossy surface, so the printer and paper combination still matters.
Hybrid ink systems
Many consumer printers use pigment black for text and dye-based color inks. Hybrid ink can produce excellent office documents and colorful graphics, but hybrid ink is not the same as an all-pigment professional fine-art system.
Which cardstock surfaces are hardest to print?
Matte cardstock, glossy photo paper, coated presentation stock, uncoated cover stock, textured watercolor paper, pre-scored blanks, adhesive-backed sheets, laminated media, and synthetic sheets all behave differently. A printer may feed a sheet correctly while ink beads, smears, dries slowly, or fails to adhere.
Canon support discussions about the PIXMA TS9521C illustrate the distinction between feeding and printing: poor ink adhesion can be a media-surface problem rather than a thickness problem. A manufacturer-approved inkjet paper with the correct coating is safer than assuming that any paper with a suitable GSM rating will work.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesWhat should you check before buying a cardstock printer?
- Find the official maximum. Give the greatest weight to a model-specific manual or manufacturer support page that states thickness, GSM, points, or a clearly defined paper category.
- Identify the required feed path. Check whether thick stock must use a rear, manual, straight-through, or one-sheet slot.
- Match the actual dimensions. Confirm support for Letter, 5 × 7 inches, 8 × 10 inches, 11 × 17 inches, A3, A3+, custom sizes, envelopes, and pre-scored cards as needed.
- Check the coating. A 250-gsm plain sheet and a 250-gsm glossy photo sheet may not be interchangeable.
- Check the printable area. Paper-size support does not guarantee borderless or full-bleed printing. Margin requirements matter for invitations and artwork.
- Check duplex behavior. Automatic duplexing is useful for ordinary documents but can cause jams, scuffing, registration problems, or ink transfer on thick stock.
- Estimate the full running cost. Include cartridges or bottles, cleaning cycles, maintenance boxes, specialty paper, failed sheets, and jammed media.
- Check office requirements. Buyers who need scanning, copying, an automatic document feeder, Ethernet, multiple trays, or a defined duty cycle should favor an office all-in-one over a photo-only model.
- Check restrictions and availability. Verify the country, current official-store listing, replacement-ink availability, subscription requirements, account requirements, and any dynamic-security or HP+ implications.
How do you print thick paper and cardstock without jams?
- Measure the media. Record GSM and, when possible, caliper in millimeters or mil. Record whether the U.S. weight is bond, cover, or index.
- Read the exact manual. Use the supported-media table for the precise printer model rather than relying on a retailer’s “cardstock compatible” label.
- Inspect every sheet. Do not use stock that is curled, warped, damp, cracked, or excessively textured.
- Load the specified path. Use the rear or manual slot when the manufacturer requires it, and load one sheet at a time if specified.
- Select the closest media preset. Look for labels equivalent to Matte, Heavy, Thick, Cardstock, Photo, or Specialty.
- Turn duplex off. Use single-sided printing unless the manufacturer explicitly supports duplex printing for the selected media.
- Set size and orientation exactly. Incorrect size or orientation settings can cause misregistration and feed errors.
- Print one test sheet. Check alignment, ink coverage, drying, edge quality, and whether the sheet exits without curling.
- Allow drying time. Do not stack freshly printed coated sheets until the surface is dry.
Driver labels vary by operating system and driver version, but the relevant controls are usually media type, quality, paper source, duplex, borderless, color management, and scaling. Use either driver-managed or application-managed color, not both, and use 100% or actual-size scaling for card templates.
What should you do when cardstock jams, smears, or fails to hold ink?
If the sheet jams
- Cancel the print job.
- Do not pull the sheet aggressively from the front.
- Follow the printer’s rear-access or official jam-removal procedure.
- Check whether the sheet is curled, warped, or beyond the documented thickness.
- Try one sheet at a time and reduce the stack.
- Select the correct media preset.
- Stop using the stock if repeated jams continue, even when the nominal GSM appears to be within the printer’s limit.
If the print smears
Increase drying time, select the correct coated-paper setting, reduce ink saturation when the driver permits it, avoid immediate stacking, and confirm that the sheet is inkjet-compatible. Glossy, laminated, and synthetic surfaces may be unsuitable even when their thickness is acceptable.
If ink does not adhere
Ink non-adhesion usually points to the paper surface or coating rather than the feed mechanism. Try a manufacturer-approved inkjet paper or a different finish. Canon’s support discussion specifically identifies media-surface compatibility as a possible cause of ink failing to adhere.

If borderless printing looks wrong
Borderless mode can enlarge the image slightly and deposit more ink near the edge. Borderless printing may also be unavailable for particular sizes, paper types, or media presets. Test the actual card blank before producing a full batch.
Is an inkjet or color laser better for cardstock?
An inkjet is usually the better choice for photographs, smooth gradients, borderless images, and specialty coated papers, while a color laser is often better for fast batches of crisp office graphics and smudge-resistant documents.
| Requirement | Inkjet advantage | Color laser advantage |
|---|---|---|
| Photos and gradients | Smoother image transitions and broader creative-media options | Usually less suited to photographic surfaces and fine tonal work |
| Borderless creative printing | Common on photo-oriented models when the size and media are supported | Often limited by printer margins and fuser requirements |
| Fast document batches | Can be slower on thick stock, especially with manual feeding | Typically attractive for crisp, repeatable office graphics |
| Smudge resistance | Depends heavily on ink and coating; drying time may be necessary | Toner is generally dry when the page exits |
| Fine-art output | Pigment photo printers offer advanced media and color-management options | Usually not the preferred tool for archival fine-art work |
Consumer Reports’ 2026 buying guide rates several color laser printers more strongly overall than many cartridge inkjets, but those broad printer scores do not specifically measure heavyweight-cardstock feeding or photographic output. A laser printer’s general office score should not be treated as a cardstock test.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What are the main printer-specific limitations?
Epson EcoTank ET-8550
The ET-8550 is the strongest general-purpose choice for genuinely thick media because its official instructions state both a thickness range and the required rear-feed workflow. The trade-offs are a high upfront price, large footprint, one-sheet feeding, and the need for regular maintenance and ink use. A tank system can reduce the cost of high-volume color printing, but tank capacity is not the same as total ownership cost.
HP OfficeJet Pro 9730e
The HP OfficeJet Pro 9730e is best understood as a wide-format office printer that can handle selected heavier media. The HP product page lists 11 × 17-inch printing and supported media up to 66 lb bond or 250 g/m2, while HP documentation gives a recommended range of 16–28 lb bond. The difference matters: a maximum specification is not a promise that every 250-gsm cardstock will feed reliably.

Consumer Reports listed an approximate $290 reference price in its 2026 buying guide, while the U.S. HP store page showed the model as unavailable when checked on August 18, 2026. The product page also advertises three months of Instant Ink with HP+. Buyers should review HP+ and dynamic-security requirements before purchase, particularly if they do not want an account-linked or subscription-oriented ink ecosystem.
Canon PIXMA TS9521C
The Canon PIXMA TS9521C is the craft-oriented option, with functions for greeting cards, labels, pattern paper, memory cards, square media, borderless projects, and automatic duplex printing. Canon’s specification sheet emphasizes supported media categories rather than one universal maximum cardstock GSM. Canon support discussions cite a 74 lb cardstock limit in one context and narrower 17–28 lb or 64–105 g/m2 limits for another media category, so the TS9521C should not be advertised as a guaranteed 300-gsm printer.
Brother wide-format MFC-J models
Brother is a sensible office-first alternative when scanning, copying, duplex documents, and business-paper handling matter more than maximum cardstock thickness. Brother’s media guidance shows that limits can be highly model-specific: one example lists index-card media at up to 120 g/m2 and 0.15 mm, while Brother also describes BP71 as a specially designed 260 g/m2 paper for certain inkjet machines. Consumer Reports’ 2026 guide lists approximate reference prices of $350 for the MFC-J6940DW and $280 for the MFC-J6540DW, but those figures are not thick-cardstock test results.
Canon imagePROGRAF PRO-series
A Canon imagePROGRAF PRO-series printer is the specialist choice for photographers and artists who value pigment-ink permanence, color management, and fine-art media more than office convenience. Canon’s professional media guide documents compatibility by printer family and media type, including professional photo papers around 300 gsm. Buyers should verify the exact current model manual rather than assuming every PRO-series printer accepts every 300-gsm sheet.

When should you use a commercial printing service instead?
A commercial printer or production machine is usually the better choice when the project involves hundreds or thousands of cards, strict color matching, consistent finishing, heavy rigid stock, scoring, cutting, or dependable turnaround. Consumer inkjets can produce excellent individual pieces and short runs, but manual feeding, drying time, failed sheets, and maintenance can make a large batch more expensive than the printer’s advertised ink cost suggests.
Pre-scored cards, synthetic sheets, laminated media, and unusually stiff stock deserve special caution. Paper weight alone cannot predict feed reliability: a light rigid synthetic sheet may be harder to feed than a heavier flexible sheet, while a fluffy porous sheet may be thick without being especially stiff.
Final buying advice
Choose the Epson EcoTank ET-8550 for the clearest documented thick-media workflow combined with photo quality and wide-format creative printing. Choose the HP OfficeJet Pro 9730e or a comparable Brother wide-format MFC when office scanning, copying, duplex documents, and tabloid output are more important than very heavy craft stock. Choose the Canon PIXMA TS9521C for craft-specific functions, but verify the exact paper category and surface. Choose a Canon imagePROGRAF PRO-series or comparable professional photo printer for archival art and photography. For production quantities, compare a commercial service or production printer instead of relying on a one-sheet consumer feed path.
Frequently Asked Questions
Can any inkjet printer print on cardstock?
No. Inkjet printers differ in supported weight, thickness, feed path, paper size, coating, and printable area. A printer may feed light card stock but reject heavy cover stock or produce poor adhesion on laminated and synthetic media.

110 lb cardstock may or may not be suitable because the meaning of 110 lb depends on whether the paper is bond, cover, or index. Check the printer’s exact manual for the paper category, GSM or caliper, feed path, and finish before printing.
Can the Epson ET-8550 print 300-gsm cardstock?
The Epson ET-8550 officially supports paper or cardstock measuring 0.61–1.3 mm through its rear feed slot, one sheet at a time. A 300-gsm sheet may fall within that thickness range, but GSM is not thickness, so the actual sheet caliper, coating, stiffness, and size still need to be checked.
Should duplex printing be used on thick cardstock?
Usually no unless the printer manufacturer explicitly supports duplex printing for the selected cardstock. Thick media can jam, scuff, misregister, or transfer wet ink during automatic duplexing, so single-sided printing is the safer default.
Is a color laser printer better than an inkjet for cardstock?
A color laser is often better for fast, crisp, smudge-resistant office batches, while an inkjet is generally better for photographs, gradients, borderless images, and specialty coated papers. The best choice depends on the cardstock, finish, quantity, and required image quality.
The Bottom Line
Bottom line: For thick paper and heavyweight cardstock, buy according to the manufacturer’s documented thickness and feed path—not a generic “cardstock compatible” label. The Epson ET-8550 is the strongest all-around choice for thick creative media, the HP 9730e and Brother wide-format models suit office work with occasional heavier stock, and professional photo or commercial equipment is safer for archival output or large production runs.
