I'm having the same sort of problem. /dev/lp0 doesn't exist. I've
tried compiling parallel port support into the kernel and using
I've edited my conf.modules with the following lines:
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7
When I run dmesg | grep par I get:
parport0: PC-style at 0x378, irq 7 [SPP,PS2,EPP]
parport0: no IEEE-1284 device present.
When I try cat >> /dev/lp0, it returns a no such device error.
If I boot to DOS, I can use dir >lpt1 and a directory will print so it
looks like the port is working. What am I missing in Linux?
I'm running SUSE 6.2 with kernel 2.2.12 (2.2.10 had same problem) on
an Abit BP6 motherboard.
When I type in lpq it says:
Warning: queue is not active (no server present).
When I type in lpc start all, I get:
lpc: connect: Connection refused
couldn't start daemon
Any ideas out there? It look like Linux isn't find lpt1 on boot up
and thus not mapping /dev/lp0. Printing worked for me about a month
ago and then all of a sudden stopped. I've been struggling with this
problem for a long time and haven't been able to get anywhere. Any
gurus out there have an answer? Please send me e-mail or post here.
