Overview
A dual-roll A1 plotter built for steady plan-set output
The Epson SureColor T3770DR is a 24-inch aqueous inkjet plotter aimed at firms that push out plan sets, permit drawings and redlines all day and want them to keep flowing without an operator standing by. It prints up to A1 (23″ x 33″), reproduces color at up to 2400 x 1200 DPI, and drives a five-channel ink set: Cyan, Magenta, Yellow, plus both Matte Black and Photo Black. That dual-black arrangement matters where the same queue mixes crisp line work on bond with a presentation board on coated stock — the blacks hold their edge on each rather than compromising on one.
Where it earns its place:
- Mixed monochrome and color plan sets on ordinary bond
- Offices that value roll flexibility and less-attended running
- Networked print rooms needing PostScript 3, PDF 1.7 and HP-GL/2 all at once
- Gigabit Ethernet and Wi-Fi submission from CAD, Revit and Bluebeam
Epson states a normal-quality A1 rate of about 120 prints per hour; treat that as engine speed, not desk-to-hand throughput. If you need more roll width and volume, the in-family Epson T7770DR 44-in is the natural step-up. Working narrower and single-roll? The Epson SC-T3700E 24-in or Epson T3465 24-in cost less to run for lighter loads.

Expert analysis
What you should know
Key takeaways
- Five-ink pigment set with both Matte Black and Photo Black handles bond and coated media without swapping blacks by hand.
- Epson rates the engine at 120 A1 pph in normal quality — a draft-mono ceiling, not a color-work figure.
- Dual-roll loading enables unattended mixed plan sets, the machine's strongest practical advantage.
- Language support spans HP-GL/2, HP-RTL, PostScript 3 and PDF 1.7 for direct CAD, Revit and Bluebeam submission.
- Maximum resolution is 2400 x 1200 DPI across a maximum A1 print width.
- No integrated scanner — as-built capture needs a separate MFP-class device.
Most conversations about a plan printer start and end with speed. But if you have ever watched a coordination set come off the roll — the MEP overlays in saturated cyan and magenta, the civil grading plan with its color-coded contours — you know the eye judges color before it judges anything else. The Epson SureColor T3770DR is a five-ink, 24-inch dual-roll machine built for exactly that mixed diet: crisp monochrome bid sets one minute, a color rendering the next.
What distinguishes it from a plain four-ink plotter is the pigment set. Cyan, Magenta, Yellow, plus both Matte Black and Photo Black — the two blacks matter more than the marketing suggests, because they let the printer switch between bond and coated stock without sacrificing black density.

Where the color actually lives
Epson rates this engine at 120 A1 pages per hour in normal quality — a figure that describes the draft mono workflow, not the color-critical one. Take that as the ceiling for a permit set, not for a presentation board.
The five-ink array is where color fidelity earns its keep. On a coordination drawing, the difference between two adjacent trades often comes down to whether a mid-saturation blue holds its hue against a nearby violet. With Photo Black available for coated media, the deep shadows in a rendered elevation stay genuinely dark rather than drifting toward a muddy charcoal. We would want to measure the gamut on your specific media before making a universal claim — the number below is on the paper our desk standardizes on, so it means something rather than nothing.

Adobe RGB coverage (by volume)47.4%
Dual roll, unattended runs, and the workflow fit
The dual-roll design is the practical heart of this machine. Load bond on one spindle and a coated or bond variant on the other, and a mixed plan set can print without an operator standing by to swap media. For a busy mid-sized practice or a general contractor’s project office running D-size and A1 side by side, that is where the hours are saved.
Connectivity is straightforward and modern: Gigabit Ethernet, Wi-Fi, USB, a touch LCD, and a language stack that covers HP-GL/2, HP-RTL, PostScript 3 and PDF 1.7 — so it drops into AutoCAD, Revit and Bluebeam workflows without a fight. The optional Epson 1TB SSD is worth a look if you reprint the same sheet sets often. Maintenance runs through the Epson Maintenance Box (Tx700/Px500), and the Epson Auto Cutter Blade is a consumable to keep on the shelf.
- Mid-sized multidisciplinary practices printing mixed mono and color coordination sets
- GC and CM project offices needing unattended dual-roll runs
- Firms producing occasional color renderings alongside routine plan output
- Teams standardized on Bluebeam and PostScript-driven submission
Estimate a plan set's run time from the Epson-rated A1 speed. Treat the result as a floor — first-page-out, roll changes and drying are not in the rated figure.
One set: – · Weekly plotting time: –
Computed from the manufacturer's rated 1,514 ft²/h (a per-page burst rating). Real-world mixed sets run slower — treat this as a best case for comparing machines, not a promise.
Where it isn't the right tool
If your work never leaves 24 inches and rarely touches color, a single-roll model such as the Epson SC-T3700E 24-in covers the same width for less complexity. Need genuine wider stock — 44-inch site plans or full E-size — and the Epson T7770DR 44-in is the honest step up in the same family. If a scanner and copy function are non-negotiable for as-built capture, this printer alone won’t do it; look at an MFP-class machine like the Epson SC-T5200 38-in instead. It’s worth putting the T3770DR next to the SC-T3700D 33-in before you commit, and cross-shopping the Canon GP-2000 24-in if you want a second read on color.
The read
The T3770DR is a considered choice for a firm whose output is genuinely mixed — mono plan sets that need to move fast, and color drawings that need to hold their hue. The dual-roll deck and the two-black pigment set are the features that justify it over a plainer plotter; the 120 pph rating is real but describes the draft end of the range, not the color end. Measure the gamut on your own media, confirm your local Epson service coverage, and this becomes an easy machine to live with. See where it lands on the 24-inch class ranking and check our measurement methodology before you sign anything.

Gamut volume is the size of the reproducible color solid in CIELAB, computed with ArgyllCMS iccgamut. Coverage is the share of the sRGB / Adobe RGB reference volume the printer reproduces (ArgyllCMS viewgam). A larger volume and higher coverage mean more saturated colors reproduced faithfully; wide-format pigment printers typically extend beyond sRGB in cyans and greens while falling short of its deepest blues.

Straight answers
What media widths does the T3770DR handle?
It prints up to A1, listed as 23″ x 33″ (594 x 841 mm). If you routinely need wider site plans or E-size, the 44-inch Epson T7770DR is the in-family step up.
How fast is it really?
Epson rates it at 120 A1 pages per hour in normal quality. That reflects fast mono draft output; color and high-quality modes will run meaningfully slower, and the rated figure excludes first-page-out time, roll changes and drying.
Which inks and maintenance parts does it use?
It uses a five-channel pigment set: Cyan, Magenta, Yellow, Matte Black and Photo Black. Maintenance runs through the Epson Maintenance Box (Tx700/Px500) or the Borderless variant, plus the Epson Auto Cutter Blade as a wear part.
Will it fit our AutoCAD and Bluebeam workflow?
Yes. It supports HP-GL/2, HP-RTL, PostScript 3 and PDF 1.7, with Gigabit Ethernet, Wi-Fi and USB, so it accepts jobs from standard CAD, Revit and PDF-based submission tools without special handling.
Can it scan and copy drawings?
No — this is a printer only, with no integrated scanner. For as-built capture and copying you would need a separate MFP-class device such as the Epson SC-T5200 38-in.
Does it support dual rolls for mixed sets?
Yes. The DR configuration carries two rolls so a mixed plan set can run unattended, which is its main advantage over single-roll models like the Epson SC-T3700E 24-in.
