Well I FUCKING FINALLY managed to build a program that makes my dad's printer print automatically.
Have ranted about this on my previous rant.
My recent approach was actually overengineered all over the top. I was using pyautogui to simulate the mouse that would call the settings window on Windows, which would print a nozzle test (the translation for "Düsentestmuster" according to google?). The more I worked with it, the more I would have had to care about edge cases when calling the settings and god knows what else...😖
So I left the idea.
What I came up with was a python script with some copy-pasted code of an example from the win32print api that printed an image that I specified, so it would use all inks. Somehow it works perfectly...
After that I used the win32api. ShellExecute() with ghostscript to print a PDF for the PGBK ink.
Finally a batch script to run this python script on the task scheduler. No converted .exe as dependencies and whatnot let it all go to hell.😒

It's not quite what I had originally anticipated as a solution but IT FINALLY FUCKING WORKS!!
...😪 It took way longer than expected and although I somehow couldn't manage to print all on 1 paper, I'm still satisfied that it really works.

That's all, had to vent my frustration and share this personal success.

Well... Just last week one guy somehow completely broken our production server while creating an WordPress using Ghostscript for some reason. First this CMS users 100% CPU, then something has happened and whole server couldn't get up. Admin had to restore it from a backup. There are around 7 client on this server and all of our projects.

Little OT but I'm about to submit my phd thesis for print and electronic publishing. Publisher scaled the A4 version to A5 but lost all links that were in the document (LaTeX & hyperref).

Tried to solve the problem by myself using Ghostscript but got lost at CropBox, MediaBox, TrimBox and page size. One day is already lost.
