Well, after recompiling a kernel, (and some other hassle) I now have a /dev/lp0 enltry for my parallel port Samsung ML-1430. Better yet, Cups detects it at the parallel port.
#: lpstat -p
printer Samsung is idle. enabled since Jan 01 00:00
Ready to print.
But, I request to print a test page, and according to the CUPS server, it immediately completes the job.
Nothing happens at the printer, not even a blinking light for data received. perhaps it is being spooled into the void, or /dev/lp0 is working as a dummy device?
