Large-format inkjet printers can help schools produce classroom posters, maps, charts, event signs, and technical drawings without sending every job to an outside print shop. The right choice depends on the width you need, how often you print, what media you use, and how easily staff can share the printer. These three models range from compact 24-inch options to a wider 36-inch printer, with different approaches to media handling and connectivity.

Our Picks: Best Large Format Inkjet Printers For Schools reviews
HP DesignJet T210: A 24-Inch Printer for Posters and CAD Work
The HP DesignJet T210 is a 24-inch printer for schools that need wide posters, maps, sewing patterns, or technical line drawings. It handles roll media and can print on sheets up to 13 by 19 inches when paired with the optional automatic sheet feeder. An automatic horizontal cutter helps finish roll-fed jobs.
HP Click software is designed to simplify file setup. Its listed features include PDF error checking, print alerts, and auto-nesting, which arranges jobs to help reduce wasted paper. The printer supports common file types such as PDF, JPEG, TIFF, DWF, HP-GL/2, and PNG. The product details also list remote management through the HP Smart app and a 500 MB memory capacity.
The supplied product information says the package includes an extra set of ink cartridges, described as providing up to a year of ink. Actual ink use will depend on what your school prints and how often. The details also claim reduced ink use for routine maintenance compared with other plotter printers, but that comparison is a manufacturer-provided claim rather than a school-specific usage estimate.
This is the most focused choice here for a school that mainly prints at 24 inches and values file-preparation tools. Its main limitation is the optional sheet feeder for larger cut sheets. Also, the supplied product data marks the listing as unavailable, so check the listing before planning a purchase.
Pros:
- Supports 24-inch rolls and larger sheets with the optional feeder
- HP Click includes file checking and auto-nesting tools
- Automatic cutter can simplify roll-fed poster jobs
- Supports CAD-oriented formats as well as common image files
Cons:
- The automatic sheet feeder is optional
- The supplied product data marks the listing as unavailable
Verdict: Choose the T210 if 24-inch poster and CAD printing fits your school’s needs and HP’s file-preparation tools appeal to your staff, but confirm that the listing is available and account for the optional sheet feeder.
Canon imagePROGRAF TM-340: A Wider 36-Inch Option
The Canon imagePROGRAF TM-340 is the widest printer in this group, with support for media up to 36 inches. That extra width can be useful for larger school displays, charts, and posters, or for projects that would otherwise need to be printed in sections. Its five-color pigment ink system is described as producing crisp text, sharp lines, and vibrant images across a variety of media types.
Media detection is a key convenience feature. After media is loaded, the printer can identify its type, width, and remaining length, which may help staff avoid setup guesswork. Automatic color calibration is included to help keep output consistent. A tilting touchscreen and animated setup and maintenance guides are intended to make routine operation easier for different staff members.
The printer ships with 300 ml of ink across its five colors. It offers high-speed USB and Ethernet connections, but the supplied details do not list Wi-Fi. That makes it worth checking your school’s network and placement needs before choosing this model, especially if you expect staff to print wirelessly from different rooms.
Compared with the two 24-inch options, the TM-340 prioritizes wider output and automatic media handling. Its larger print capacity can be valuable, but it may be more printer than a school needs if most jobs fit within 24 inches. The product details also identify it as ENERGY STAR and EPEAT Gold rated.
Pros:
- Prints on media up to 36 inches wide
- Five-color pigment ink system
- Detects media type, width, and remaining length
- Includes USB and Ethernet connectivity
Cons:
- Wi-Fi is not listed in the supplied connectivity details
- Its wider capacity may be unnecessary for schools that only need 24-inch output
Verdict: Pick the TM-340 if your school needs prints wider than 24 inches and wants media detection and a touchscreen, and confirm that its wired connectivity suits your setup.
Canon imagePROGRAF TC-21: A Compact 24-Inch Printer with Wi-Fi
The Canon imagePROGRAF TC-21 is a 24-inch desktop roll printer that can also handle cut sheets through its automatic sheet feeder. It is designed for schools that want wide-format printing without stepping up to a 36-inch model. Its four-color ink system is intended for posters with crisp text and vibrant images.
The TC-21 ships with 280 ml of ink, with 70 ml for each color, according to the supplied product details. Its top and front interior access is designed to make ink refills, roll changes, and maintenance easier. A tilting touchscreen and animated installation guides can also help staff get through initial setup and routine tasks.
Connectivity is a notable advantage for shared school use: the printer includes USB, Ethernet, and built-in Wi-Fi, with wireless printing from computers, smartphones, and tablets listed in the product details. Its automatic sheet feeder also makes it more flexible for schools that use both roll media and cut sheets. Unlike the T210, the listed features do not call out CAD-focused software tools; unlike the TM-340, it is limited to 24-inch media.
The TC-21 is identified as ENERGY STAR and EPEAT Gold rated. Its combination of roll and sheet handling is useful, but schools that need very wide displays should look at the 36-inch TM-340 instead. The supplied details do not list automatic media detection, so staff may need to pay closer attention to media selection.
Pros:
- Supports 24-inch roll media and cut sheets through an automatic feeder
- Includes Wi-Fi, USB, and Ethernet connectivity
- Ships with a full set of ink totaling 280 ml
- Top and front access supports routine refills and maintenance
Cons:
- Its maximum listed width is less than the 36-inch TM-340
- Automatic media detection is not listed in the supplied details
Verdict: The TC-21 is a strong fit for schools that need a 24-inch roll-and-sheet printer with wireless connectivity and accessible maintenance.
How to Choose a Large Format Inkjet Printer for a School
Match the Printer Width to Your Projects
Start by measuring the largest output your school expects to print. A 24-inch printer can suit many posters, maps, classroom displays, and technical drawings. If your projects need to be wider than that, the 36-inch Canon TM-340 is the only option in this group with the listed capacity. Choosing more width than you need can add complexity without helping your everyday jobs.
Decide Whether You Need Rolls, Cut Sheets, or Both
Roll media is useful for long prints and flexible poster lengths, while cut sheets can be convenient for defined-size projects. The HP T210 supports roll media and can use sheets up to 13 by 19 inches with an optional feeder. Both Canon models include an automatic sheet-feeding option in their listed features, and the TC-21 is described as handling rolls and cut sheets. Check the media sizes you use most before deciding which workflow matters more.
Consider Ink Use and Refill Planning
Ink capacity and the number of colors can affect how you plan supplies, but they do not guarantee a specific number of prints. The TC-21 ships with 280 ml across four colors, while the TM-340 ships with 300 ml across five colors. The T210 package is described as including an extra set of cartridges and up to a year of ink, though real use depends on print volume, image coverage, and maintenance. Compare the stated ink system with your school’s expected workload.
Check How Staff Will Connect and Share the Printer
A printer used by several teachers or departments should fit your school’s network. The TC-21 lists Wi-Fi, USB, and Ethernet. The TM-340 lists USB and Ethernet, while the T210 product details describe management through the HP Smart app and HP Click but do not specify the same connection options in the supplied data. Confirm network compatibility, user access, and the devices staff plan to print from before ordering.
Look at File Handling and Setup Tools
Schools may receive files from teachers, students, administrators, or outside organizations, so support for common file types can save time. The T210 lists formats including PDF, JPEG, TIFF, DWF, HP-GL/2, and PNG, along with HP Click tools for checking and arranging jobs. Canon’s TM-340 includes a touchscreen, animated setup guidance, media detection, and automatic color calibration. The TC-21 also includes a tilting touchscreen and animated installation guides.
Plan for Space and Routine Maintenance
Wide-format printers need a suitable location for the printer, media, and finished prints. Consider how staff will load rolls, access the ink, and handle longer sheets in the room where the printer will live. The TC-21’s top and front access is specifically described as helping with refills, roll changes, and maintenance. For any model, make sure the space and staff workflow are practical before choosing based on print width alone.
