Description of problem:
Cannot get Lexmark printer Optra E312 working with Red Hat Linux 7.1, 
using parallel port and Acer Travelmate 600TER computer.

How reproducible:
Always

Steps to Reproduce:
1.Boot
2.Printer device not found
3.Verify with dmesg that following line appears :
lp: driver loaded but no devices found
	

Actual Results:  Nothing. Cannot print to the printer in any fashion, 
Postscript, text only printer driver, absolutely nothing works at all. The 
system cannot see the printer device. Period.

Expected Results:  The printer device should of course be recognized. 
Please note that this computer is setup as dual boot and the exact same 
system works perfectly well with Windows 98 and LPT1.

Additional info:

Lexmark has refused to help me with this problem, because they have not 
written a driver for redhat 7.1 yet. Their download package for v7.0 does 
not work, nor do the drivers shipped with the printer. They will not say 
when they have a driver release planned to resolve this issue.
