Re: Parallel Printer Port Problem

[JParker@coinstar.com]

G'Day !

Well at least the laptop now sees the printer ... that is probably the hard part.  I think you now have to read the Printing-HOWTO very carefully, and make sure your permissions are correct (always bite me in the past  ;-)

Are you able to print anythng on the printer (ASCII text perhaps) ?  Can you print as root ?  My HP Deskjet did the same thing for awhile, turned out it was problems with the /etc/printcap file.

Good luck.

cheers,

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.

Any ideas...please?
