Use script as custom printer driver to send file to web page

At my workplace, I am unable to find a printer driver for macOS which works with the printer. Instead, I'm printing through the web-interface of the printer, and I'm wondering if there's a way to automize this. **The steps I do manually that I want to automize (all or some):** 1. Save document as .ps (works better than .pdf for this printer) 2. Go to the web address and log in to the printer 3. Drag the file I want to the browser UI Writing a script to simulate the web login and transmission of the file is a separate problem which I think I can solve. **My question:** Can I use this custom script (probably Pyhton) as a "printer driver" to make it show up in the list of printers and enable me to print using *cmd-p*? It would have to automatically save as .ps and then do the webb stuff.
