What you should know
Key takeaways
- The T770 is a 24-inch, color, print-only wide-format device with cut-sheet and single-roll media handling.
- Its maximum A1 output size is 23 × 33 inches, making it suited to office-scale drawing and document work.
- HP lists a normal-quality speed of 445 ft/h, but completed set throughput depends on real workflow interruptions.
- The listed operating-system support is legacy-oriented, so driver and network validation are essential before continued deployment.
- The HP DesignJet T830 24-in is the more relevant family alternative when scanning and copying are required.
- A single roll input limits its suitability for teams that frequently switch media types or sizes.
For a small project team, the familiar test is a permit set that needs one more 24-inch sheet before a meeting: clear linework, a legible revision cloud, and no detour to a reprographics counter. The HP DesignJet T770 24-in Printer with Hard Disk is a color, print-only wide-format device built around that office-scale AEC role. It accepts cut sheets and roll paper up to 24 inches wide, with a maximum A1 output size of 23 × 33 inches.
This is a discontinued machine, so the decision is usually about supporting an installed unit or judging a replacement candidate—not starting a fresh standardized fleet. Its 2400 × 1200 DPI maximum resolution, six cartridges, Ethernet, USB Type-A connection, LCD, and 160 GB internal storage describe a capable earlier-generation plotter. They do not, by themselves, settle whether it fits a current IT environment or a busy print room.

Where it still makes operational sense
The T770 fits an architecture studio, field-office engineering group, or contractor’s project office that primarily needs occasional-to-regular 24-inch drawings, color-coded coordination sheets, GIS maps, and presentation-oriented PDFs. It can take bond, coated, photo, and roll media, and it supports both cut sheets and a single roll. That flexibility matters when a team alternates between a plotted drawing and a smaller sheet without dedicating floor space to a larger device.
The machine is print-only. Firms that scan marked-up plans, copy legacy drawings, or need a single walk-up device for both paper-to-digital and digital-to-paper work should look instead at the HP DesignJet T830 24-in, which is listed as a scanner/MFP. The T770’s 56.7 × 30.3 × 23.6-inch footprint and 134.5 lb weight also warrant a deliberate location rather than an improvised desk-side placement.
Estimate plot time from the verified rated speed, then allow practical room for PDF processing, roll loading, trimming, and collection.

Computed from the manufacturer's rated 693 ft²/h. Real-world mixed sets run slower — treat this as a best case for comparing machines, not a promise.
The limitations are mostly about workflow age
Its listed operating-system compatibility centers on Windows XP through Windows 7, Windows Server 2003 and 2008, selected Mac OS X versions, Novell NetWare, and Citrix environments. That makes driver validation, network segmentation, and service planning central questions for IT—not afterthoughts. The Ethernet interface is Fast Ethernet, with one RJ-45 port, and the unit has one USB 2.0 port.
There is one roll input, so this is not the natural choice where teams continually switch between bond and presentation media or must keep multiple stock sizes ready. A wider option such as the HP DesignJet T770 44-in changes the maximum drawing width, while the HP DesignJet T1600dr 36-in is the more relevant in-family direction for dual-roll operation. Neither comparison removes the need to assess local support and current software compatibility.
Color and drawing output: keep the claim proportional
The six-cartridge system uses 6 pl drops for cyan, magenta, photo black, and gray, and 9 pl drops for yellow and matte black. That is useful technical context for mixed CAD and color-document work, but it is not a measured statement of gamut, color accuracy, or photographic rendering. No measured ICC-gamut result is available for this machine here, so firms with controlled presentation-color requirements should test their own PDFs and media rather than infer the result from resolution alone.
For straightforward 24-inch AEC plotting, the more practical question is whether the existing unit renders the firm’s line weights, screened fills, and small annotations consistently on its chosen bond. Compare the workflow fit with the HP DesignJet T650 24-in as a current smaller-format family alternative, or use the comparison tool for the T770 and Canon GP-200 24-in to frame a same-width review.

The read
The HP DesignJet T770 24-in Printer with Hard Disk remains a sensible installed-base plotter when its job is clear: 24-inch color and monochrome AEC documents from a stable, validated legacy environment. It is less appropriate for scan/copy workflows, unattended mixed-media output, wider sheets, or organizations that cannot support its older listed operating-system ecosystem. Its successor decision should begin with workflow width, roll-switching needs, and IT support—not with resolution alone.

Questions
Straight answers
Can the HP DesignJet T770 24-in handle typical AEC plan sizes?
It supports media up to 24 inches wide and a maximum A1 print size of 23 × 33 inches. It accepts both cut sheets and roll paper.
Is this a multifunction printer for scanning marked-up drawings?
No. Its listed function is print. The HP DesignJet T830 24-in is listed as a scanner/MFP for teams needing scan and copy capability.
How fast is the T770?
HP lists normal-quality print speed at 445 ft/h. Actual plan-set turnaround will also depend on file processing, media handling, and operator intervention.
Will it work on a current office network?
It has one Fast Ethernet RJ-45 connection and USB 2.0, but the listed supported operating systems are centered on legacy Windows, Mac OS X, server, NetWare, and Citrix environments. Confirm driver and security compatibility in your specific environment.
Does the T770 support multiple rolls at once?
No. The specification lists a maximum roll input of one. A dual-roll workflow points toward the HP DesignJet T1600dr 36-in instead.
