| |
Andreas Muck <andi@koala.rhein-neckar.de> said me that he couldn' t print also in polling mode with my 2.1.104 lp patch when he was using the SoundScape soundcard at the same time. He was using the parallel port in ECP (or ECP+EPP), I suggested him to try normal mode and now lp works fine for him too also when the soundcard is running. So I suggest people that is having printing troubles with 104 to set EPP mode (that works too) in the BIOS at least for now.
Here the Andreas' data when its parallel port is in ECP, when the printing breaks:

I will sent to Andreas some debugging patch soon to understand at least if the bug is in the parallel-port or in the parport code.
