Python module to send HP-GL code to a 7475A plotter
Clone this repository and cd into the directory:
git clone https://github.com/b4ckspace/hpgl-plot
cd hpgl-plot
You should install the module and its dependencies in a Python virtual environment. To create and enter one, execute:
virtualenv env
source env/bin/activate
To install the sendhpgl module along with its deps, run:
pip install .

You should install the module and its dependencies in a Python virtual environment. To create and enter one, execute:
python -m venv env
env\Scripts\activate
To install the sendhpgl module along with its deps, run:
pip install .
The module takes two arguments:
- The serial port your plotter is connected to (probably /dev/ttyUSB0) or COM.. for Windows
- The path to your .hpgl file
To run it, execute the following while inside the venv: eg Linux
sendhpgl /dev/ttyUSB0 path/to/file.hpgl
Windows
sendhpgl COM3 path\to\file.hpgl
Your device should now start plotting.
- If after an SP your plotter places a dot at its previous position, you should insert a
PUcommand before eachSP. It will still move to its last position, but it won't drop the pen.
