Re: Parallel Printer Port Problem
Well, it's still doesn't work. I've added an options line in the /etc/modules.conf file specifying io=0x378 dma=3 irq=7. With lp reloaded, I see in the /proc/parport/0 that these options are set and that my printer is being seen. The syslog shows the following:
Jan 4 07:36:20 localhost kernel: parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [SPP,ECP,ECPPS2]
Jan 4 07:36:21 localhost kernel: parport_probe: succeeded
Jan 4 07:36:21 localhost kernel: parport0: Printer, HEWLETT-PACKARD DESKJET 950C
Jan 4 07:36:21 localhost kernel: lp0: using parport0 (interrupt-driven).
I've re-installed magicfilter, but that didn't help either.
