Large Format
Printers
for Architects & Engineers
A0 and A1 CAD plotters for technical drawings, site plans and engineering schematics. The right printer for your workflow, with authorised service and support across the UK.
What Architects & Engineers
Actually Need from a Printer
Most large format printer advice is written for sign makers. Architecture and engineering firms have fundamentally different requirements — precision, speed, paper handling and the ability to work within BIM and CAD workflows without friction.
Line Precision
CAD drawings require absolute line accuracy. A plotter that smears or misregisters lines renders drawings non-compliant with BS 8888 and ISO 128 technical drawing standards.
Output Speed
Deadline-driven practices need consistent throughput. A plotter that slows under continuous A0 load creates workflow bottlenecks at exactly the wrong moment.
Media Handling
Bond paper, tracing paper, vellum and polyester drafting film all behave differently. The wrong plotter or wrong settings causes media jams at critical moments.
Network & Workflow
Integration with AutoCAD, Revit, MicroStation and BIM software matters as much as the hardware. A plotter that requires workarounds adds time to every single print job.

What to Look for in a
CAD Plotter
Not every large format printer spec matters equally to architecture and engineering.
Here is what actually makes a difference in a technical drawing environment.Below is a reference guide our specialists use when recommending a plotter to architects, engineers and reprographics teams. The table is filterable by importance level.
| Specification | Why it matters for CAD | What to look for | Importance |
|---|---|---|---|
| Print resolution | Fine lines and text must be sharp at A0. Low resolution causes jagged edges on diagonal lines. | 2400 × 1200 dpi minimum for technical line work | Essential |
| Print width | A0 is 841mm wide. Most standard plotters handle 24" (A1). A0-capable models are wider. | 36" (914mm) for A0 output; 24" (610mm) for A1-only | Essential |
| First page out | Deadline-driven practices need consistent throughput. Slow warm-up adds minutes per print in busy offices. | Under 25 seconds for A1; under 35 seconds for A0 | Essential |
| Memory / processor | Large CAD files (Revit exports, complex PDFs) require processing power. Under-spec'd printers spool slowly or drop data. | 1GB+ RAM; dedicated graphics processor | Essential |
| Roll vs sheet feed | Roll-fed plotters are significantly more cost-effective for A0 volume. Sheet feed suits low-volume offices. | Dual-roll for high volume; single roll for typical office use | Important |
| Scan / copy (MFP) | Many firms need to scan and archive existing drawings, particularly on heritage or renovation projects. | Integrated scanner at A0 for reprographics use | Important |
| Software compatibility | Direct print from AutoCAD, Revit and MicroStation without driver issues. HP provides dedicated AutoCAD drivers. | HP DesignJet or Epson SureColor T — both have native CAD support | Important |

Not Sure Which CAD Plotter Is Right for Your Practice?
Most practices need A0 output, but the right choice also depends on your print volume, whether you need scanning, and how your workflow connects to AutoCAD, Revit or MicroStation.
Our specialists will give you a clear, honest recommendation with a cost-per-print comparison — no jargon, no obligation. We can also run both HP and Epson on your actual files before you decide.
