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 :-)
