Thank you very much. This, first of all, shows me what homework I still have
to do due to lack of knowlegdge. I will give it a shot.
Thanks

That's just an evolution of the ultra-classic Epson dot matrix
printers, and it speaks the ultra-classic ESC*P2 print job format.
Based on terminal-style bare ASCII, including control characters that
make sense on a printer, enriched with "escape sequences".
The printer still takes that format on the respective USB endpoint.
All that you're missing is a class-based USB LPT driver for DOS.
(If you use crude transport over Samba to BSD LPD, it works.)
A quick google has shown to me the following open-source project:
https://github.com/crazii/USBDDOS
...an effort in the right direction, i.e. a layered stack, but contains no
driver for USB LPT class devices, and even the included class-based CDC
(serial) driver is not a fully functional TSR exporting a COM device in DOS
- it's a mere C library for anyone interested to call some functions to talk
to the "virtual serial"
endpoints...
Do I volunteer to try to extend this? No :-)
