Pen plotter utilities and GUI for image conversion, SVG optimization, HPGL conversion and headless print

HP7475a Pen Plotter Utility

Python GUI to simplify working with pen plotters:

• Now supporting: Graphtec MP4200, HP7475a
• Standalone version for Raspberry PI headless printing.
• Telegram notification on print ended
• Poweroff your plotter on print end using a Tasmota-enabled Sonoff controller
• Combine CMYK Split with Flow Imager

Installation

Create a virtual environment:

python3 -m venv venv
source venv/bin/activate

Plotter Utility uses:

• vpype Installation instructions
• vpype-flow-imager Installation instructions
• svgo Installation instructions
• cmyksplit Installation instructions

After installing the dependencies, use Python package manager pip to install the requirements for the GUI.

pip install requirements.txt

Or, if using the standalone version, just run

pip install requirements_standalone.txt

Usage

For the GUI interface run:

python main.py

For the standalone headless version

python main.py

To keep the print running when closing the SSH connection, I suggest using a terminal multiplexer like screen
