and came to understand that the printer serial protocol is non-standard and
documentation for it is hard to find. Someone also mentioned some Nuts and

The protocol is essentially the same protocol as commodore 1541 disk
drive protocol is. The printer just uses device number 4 instead of 8.

Trust me, it is much easier to find a suitable matrix printer for your
PC than to attach the commodore printer to your pc. The cbm protocol is
very tight in timing.

Sell the printer to someone c64/vic20/c128 enthusiast.
