Printtool not seeing my printer on /dev/lp0, /dev/lp1 or /dev/lp2

           Hi, I've just started using Linux having used Unix in the past.
I've got a problem and I'm hoping that someone may be able to suggest a
solution.

     Having successfully installed Linux( Red Hat V6.0 Kernel 2.2.5-15 on a
Dell Dimension PIII 500Mhz ) and selected a printer driver I set up my
spoolers and ensured lpd was running. However while logged in as root trying
to redirect the output of a 'cat' command directly to the printer yielded no
output from the printer. Having checked with some FAQs and support sites I
note that the Epson Color 440 ( the printer I'm trying to use ) should be
completely compatible with Linux. I noticed an article which spoke about the
'stcolor' driver but this seemed more to do with the quality of the output
rather than the fact that there was no output at all. I tried running
printtool and it said that it could find no devices attached to /dev/lp0,
/dev/lp1 or /dev/lp2. According to Windows '98 the printer is installed on
the "ECP Printer Port" LPT1. My modem is installed on COM2( INT 9, Addr. 0 )
while COM1( INT 4, Addr. 3F8, UART NS 16550AN) does not have anything
attached. The printer works fine with Windows '98.

Any help you could give me would be greatly appreciated.

Thank You

James.

I had a similar problem with RedHat 6.1.  The fix was to put a line in
my
/etc/conf.modules file:

alias parport_lowlevel parport_pc

and then run:

modprobe lp

(That modprobe lp will be run at bootup, automatically).

Then I ran printtool, and it worked fine.  But it's strange that my
parallel port worked fine out-of-the-box with RH 6.0, which is what you
have...

 
 
 

1. dev/lp0 (or lp1 or lp2) not detected for printer

When I attempt to install a printer, I use the RedHat control-panel printer
control. It says it cannot detect any parallel ports  (/dev/lp0, /dev/lp1,
/dev/lp2) and there might be a hardware error. I'm puzzled because I have
been able to use the p-port successfully for a zip drive. (I do the printer
configuration without the ppa module loaded.) I must be missing something.
Any ideas?

Thanks,

2. NFS and system hangs

3. /dev/lp0 nor /dev/lp1 getting detected

4. how to let the machine display .plan?

5. What is the difference between /dev/sg0, /dev/scd0 /dev/hdd and /dev/cdrom ?

6. Gcc and libraries.

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

8. Remote printer jobs enqueuer?

9. Printing problem : ls > /dev/lp0 -- /dev/lp0 : No Such Device ?

10. /dev/dsp, /dev/audio, /dev/midi., /dev/sndsta

11. lp0, lp1 and lp2 cannot be found in printtool

12. /dev/lp0 not seen
