OmniPlot

OmniPlot Cut Agent v1.2.0

Cut from any browser.
Any OS. Any cutter.

A 9 MB background daemon that sits between OmniPlot and your vinyl cutter — so Firefox, Safari, and every other browser can send jobs over USB or serial, no Chrome required. Free, forever.

How OmniPlot connects to your cutter

Four ways to cut. One studio.

OmniPlot isn't locked to any single output path. Every shop is different — pick the method that fits your setup, and switch any time in Plotter Settings.

Recommended

Cut Agent

Run our lightweight daemon once. OmniPlot sends jobs to it over localhost HTTP — works in every browser including Firefox and Safari, on Mac, Windows, and Linux.

  • Works in any browser
  • Auto-detects your cutter port
  • Lists all available serial ports
  • Survives browser restarts
  • Supports all baud rates

Requires: one download per machine

USB-Serial

Web Serial API

Chrome and Edge have direct USB-serial access via the Web Serial API. Connect your cutter, click "Connect port," and cut — zero installs, zero agents.

  • Zero install required
  • Port remembered per-session
  • Instant — no daemon startup

Requires: Chrome or Edge only

Network

TCP / JetDirect

Network-connected plotters (HP JetDirect on port 9100, Graphtec network models) receive HPGL over TCP — routed through our server-side proxy.

  • Works with ethernet plotters
  • Any browser, any OS
  • No USB cable needed

Requires: plotter on same network

Download PLT

Manual HPGL file

Export a standard .plt HPGL file and open it in your cutter's software — Graphtec Pro Studio, Roland VersaWorks, CutStudio, or any compatible tool.

  • Works with any existing software
  • No connectivity required
  • Transfer via USB drive

Requires: cutter software on hand
