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.

Instead of lp0 try to use lp1. It should work. I had the same problem when
I first installed linux too. I guess dos LPT1 is lp1 under linux. But
don't ask me what lp0 then :-)

hope that helps..

lp0 is the parallel port on a monochrome graphics adapter, lp1 and
lp2 are the first 'normal' parallel ports.

well, are you sure your kernel is set up to support parallel printers?
to be safe (and to have some fun) grab the kernel sources off of
sunsite.unc.edu or tsx-11.mit.edu
and make your own kernel.
you can add options you need, and dump those you don't... it'll be better
for you, and faster, probably.
btw, if you think you might need more than 2 serial ports, add the line

#define CONFIG_AUTO_IRQ

to the beginning of /usr/src/linux/drivers/char/serial.c

it'll let you use non-standard IRQs for serial ports.
i think it should be default, and will always add it for friends' machines.

in the printing.HOWTO it says...

2.13 Printer device names
=========================

On an XT bus system `LPT1:' becomes `/dev/lp0' (major=6, minor=0),
on an AT `LPT1:' becomes `/dev/lp1' (major=6, minor=1). To be more
precise:

Name Major Minor I/O address
lp0 6 0 0x3bc
lp1 6 1 0x378
lp2 6 2 0x278

get it, read it. It will help with most of the problems I've seen.

If you try everything in there, and it still doesn't work look for
message at startup looking something like...
lp_init: lp1 exists, using polling driver

If you don't see it parallel printer support is probably not in your
kernel, and your going to have to recompile it.
