I think the first thing which needs to be done is verifiy that the
printer is on /dev/lp1, as i said before normaly speaking we know
that such a device would be on /dev/lp0, may i suggest the use of
cat /proc/ioports.
An example of /dev/lp0 =
0378-037f : parport0
0778-077a : parport0
The parport0 first shows 0378 which is correct, the second now i dont
know why it appiers, but my printer is on /dev/lp0.
Of course cat ioports needs to be done after loading of the modules.
Now i forgot to answer things in my last message, one was about how
to start kerneld automaticly, normaly speaking it should be started
at bootime, at least its my understanding that Redhat starts it
automaticly, now if it does not start then use 'linuxconf' to start
it automaticly, thier is no need to put it into rc.local as that is
way to late to start it, it needs to be started at the start of the
boot process.
Another was parport_probe, that module should get loaded as soon as
you issue any command to print, or you do modprobe lp, but it is not
needed for the printer, it will dissapier automaticly as it is not
needed, that could happen before you get chance to do lsmod, or it
could take five minutes, it just depends on where the scheduler is in
its cycle, thats the reason you did not see it.
Now i see what the file pbm2ppa is, i did not know i was so dense ;-)
It would be beter to add the path of pbm2ppa as follows.
#!/bin/sh
pbm="/usr/sbin/pbm2ppa"
cat $1 | gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- |
$pbm - - > /dev/lp1
Once again do we know the printer is on /dev/lp1 or lp0 ??
And i am presuming pbm2ppa is in /usr/sbin/
Not having pbm2ppa i cant say how it works or say what the options
are, what does look fishy is the -s option OutputFile, is it meant to
be substituted with a real file name, i'm sorry i can help there and
also sorry if i am confusing the issue even more.

Thats true.
