/dev/lp0 does not exist in RH 6.1

/dev/lp0 does not exist in RH 6.1

Post by Jorge Collaz » Sun, 31 Dec 1899 09:00:00



I just installed RH 6.1 and the printer does not work.  Printool does
not detect either /dev/lp0 , lp1, or lp2.  When I try to cat to /dev/lp0
the device does not exist.

The port is at 0378 irq 7 and works perfectly in DOS, Win98, and
Caldera.

How can I make the device?

Hi,

this is a solution: add to the /etc/conf.modules the following line:

alias parport_lowlevel parport_pc

This will work...

Good luck

Huub

Sounds as if you dont have support in the kernel, check out
/usr/src/linux/Documentation/modules.txt and parport.txt...

I believe printer support as a module should be all set up. You need
to get the printer module working - I think this will create the
device file for you, but I'm not sure.

Try adding this to modules.conf:

alias           /dev/printers   lp
alias           /dev/lp*        lp
alias parport_lowlevel parport_pc

Then do some modprobes (modprobe each alias, I think?) or reboot.

I still had to add the printer via printtool after doing this, it took
a few tries but eventually it worked fine. The lpq command is very
useful here.

If memory serves, I got some good information on this topic from the
printing HOWTO at www.picante.com (note that this is not an official
LDP HOWTO, so you won't find it at any of the LDP mirror sites).

1. ls > /dev/lp0 fails--but /dev/lp0 exists

I'm new to Linux.  I just loaded the Slackware distribution onto Swan 386SX,
386DX/25 and 486DX.  I have the same problem on all of them:

ls > /dev/lp0 gives:    
    bash: /dev/lp0: no such device.

ls -al /dev/lp0 gives:  
   crw-rw----  1  root  lp   6,  0  Nov 30 14:30  /dev/lp0

Nothing prints.  

All these machines print fine on lpt1: under DOS.  I've read the
print HOWTO and "Linux Installation and Getting Started."   On the 386SX,
uname -a gives:  
    Linux alinux 1.0 #9 Tue Mar 15 18:27:34 CST 1994  i386

I'd appreciate any help you can give.
