What you should know
Key takeaways
- The T1120 is a 24-inch color technical printer aimed at D-size AEC drawings and project graphics.
- HP rates draft A1 color line drawings at 35 sec/page, but mixed sets take longer once processing and handling are included.
- Its +/- 0.1% line accuracy and 0.002-inch minimum line width suit detailed CAD and GIS-style output.
- One roll, rear single-sheet feed, automatic cutting, and basket output fit a focused office workflow.
- The lack of duplexing, scanning, and second-roll capacity limits its fit for busy central print rooms.
- The HP DesignJet T1600dr 36-in is the stronger in-family option when wider output and dual-roll operation matter.
At 4:45 p.m., somebody wants a revised D-size coordination set, a color utility map, and maybe one clean board for tomorrow’s meeting. The HP Designjet T1120 24-in Printer is built for that kind of office-side production: 24-inch roll output, occasional sheets, and CAD/PDF work that cannot wait for a central print room.
It is a color inkjet technical printer with HP-GL/2 and HP-RTL support, Ethernet and USB connectivity, an embedded web server, and an 80 GB hard drive. For architects, engineers, surveyors, and contractors working mainly through D-size, it covers the practical middle ground between desktop printing and a wider production device.

Where it earns its floor space
The T1120’s job is straightforward: produce technical drawings without sending every plan set downstairs, across town, or into a queue that has developed opinions. HP rates draft A1 color line drawings at 35 seconds per page and 56 A1 prints per hour on plain paper. Those are rated figures, not a promise that a mixed PDF set will land at the basket at that pace. File processing, roll changes, sheet loading, and the person who notices the wrong revision all get a vote.
Its 0.002-inch minimum line width and +/- 0.1% line accuracy are the specifications that matter more than a glossy brochure image. They suit CAD linework, civil exhibits, MEP coordination drawings, survey maps, and marked-up construction documents. The five-color ink system includes cyan, magenta, yellow, matte black, photo black, and gray, so color-coded layers and presentation sheets are within its lane as well.
Bottom line: This is a credible office plotter when D-size technical output is the daily job.
Media, workflow, and the one-roll reality
The printer accepts one roll up to 24 inches wide, plus rear single-sheet feeding, and includes an automatic cutter and output basket. It supports bond, coated papers, technical papers, films, photographic media, backlit material, and selected self-adhesive media. That gives a small AEC team useful range: ordinary bond for issue sets, coated stock for color plans, and specialty media for a project-room graphic. It does not give you a second roll waiting in the wings.
That matters when one team wants plain bond and another wants coated color output. A one-roll device means a media swap. Media swaps are not dramatic, but neither is staying late to finish a permit set. The T1120 supports custom media from 216 x 279 mm to 24 x 66 inches and can print up to 300 feet, subject to operating system and application limits.
Network administration is reasonably practical for its generation. Gigabit Ethernet, HP Web Jetadmin, HP Printer Utility, an embedded web server, and the 80 GB drive support shared-office management. Its listed operating-system support is legacy-oriented, so IT should validate driver and submission workflow before placing it on a modern managed network.
Bottom line: One roll is fine for a focused workflow; it is the bottleneck when media switching becomes routine.
Estimate rated plot time for a run of draft line drawings, then allow working time for file preparation, media handling, and set assembly.

Computed from the manufacturer's rated 485 ft²/h. Real-world mixed sets run slower — treat this as a best case for comparing machines, not a promise.
Where it sits in the family
The closest same-width alternative is the HP DesignJet T1120ps 24-in. Both are 24-inch models with 2400 x 1200 DPI listed in the catalog. For teams that routinely need wider sheets, larger plan formats, or a scanner/MFP configuration, the HP DesignJet T1120 44-in changes the conversation by moving to 44-inch output and adding scanner/MFP capability.
For a more current wider technical-print workflow, the HP DesignJet T1600dr 36-in is the relevant step-up in this catalog because it is a 36-inch dual-roll model. That second roll changes daily behavior more than it changes a spec sheet: plain bond can remain loaded while coated media stays ready. Compare the T1120 directly with the T1600dr 36-in if roll switching and wider documents are part of the weekly workload.
The T1120 is less appropriate for frequent wide-format scanning, unattended mixed-media production, or teams whose work regularly exceeds D-size. It also has no duplex option. That is normal for this kind of plotter, but it should not be discovered during a deadline.
Bottom line: Choose the T1120 for concentrated 24-inch plotting, not as a substitute for a wider, dual-roll, scan-heavy department device.

The read
The HP Designjet T1120 24-in Printer fits a small architecture, engineering, survey, or construction office that needs dependable D-size color and monochrome plotting from roll or sheet media. Its strengths are technical line output, broad media support, shared-network management, and a compact 24-inch format. The trade-off is capacity flexibility: one roll, no duplexing, and no scanner/MFP function. If the workflow is mostly CAD/PDF plans on one primary stock, it makes sense. If every day involves switching rolls, scanning legacy drawings, or printing beyond D-size, move up rather than asking this machine to become a print room.

Questions
Straight answers
What AEC documents does the HP Designjet T1120 24-in Printer suit?
It is suited to D-size and smaller CAD drawings, coordination plans, survey maps, color-coded engineering documents, construction markups, and selected presentation sheets. It supports HP-GL/2 and HP-RTL, which are relevant to technical drawing workflows.
How fast is it for plan printing?
HP rates draft A1 color line drawings at 35 sec/page and 56 A1 prints per hour on plain paper. Actual set turnaround depends on file processing, media changes, job order, and operator handling.
Can it print both bond plans and coated color graphics?
Yes. It supports bond, coated, technical, film, photographic, backlit, and selected self-adhesive media. It has only one roll input, however, so changing between loaded media requires operator intervention.
Does the T1120 scan drawings or make wide-format copies?
No scanner or MFP capability is listed for this 24-inch model. The HP DesignJet T1120 44-in is the in-family catalog option listed with scanner/MFP capability.
What should IT check before deploying it?
Confirm driver compatibility with the current workstation and print-management environment. The listed supported operating systems include Windows Vista, Windows XP, Windows Server 2003/2008, Mac OS X v10.4/v10.5, Novell NetWare, and Citrix environments, alongside Ethernet, USB, HP Web Jetadmin, and an embedded web server.
