Very Computer

Hello I really need to have some resumes printed, so here I am:

as mentioned above, Linux can't detect my /dev/lp0 nor /dev/lp1. It worked
fine before the RH5.2 to RH6 upgrading.

I thought it was because of my soundcard and the isa PnP tools, as my Linux
Box is an isa one (i486). I tried so many things, de-slotted the soundcard,
updated to kernel 2.2.5-22 and to the last -RedHat- 'dev' package, but it
doesn't works. Here's some details:

- after the RH5.2 to RH6 upgrade, my '/dev/lp' symbolic link desappeared. I
re-created it.
- of course, PrintTool doesn't find any /dev/lpx with a printer attached
- 'cat test.file >/dev/lp1' returns a not found device message, even an 'ls
/dev/lp?' shows the three /dev/lpx
- the parallel port (/dev/lp1) never appears in /proc/ioports nor in
/proc/interrupts:

Here is my /proc/ioports: (the parallel port, /dev/lp1, should be at 0378)
0000-001f : dma1
0020-003f : pic1
0040-005f : timer
0060-006f : keyboard
0070-007f : rtc
0080-008f : dma page reg
00a0-00bf : pic2
00c0-00df : dma2
00f0-00ff : fpu
0170-0177 : ide1
01f0-01f7 : ide0
0220-022f : soundblaster
02f8-02ff : serial(auto)
0300-031f : NE2000
0330-0333 : MPU-401 UART
0376-0376 : ide1
03c0-03df : vga+
03f6-03f6 : ide0
03f8-03ff : serial(auto)
0620-0623 : sound driver (AWE32)
0a20-0a23 : sound driver (AWE32)
0e20-0e23 : sound driver (AWE32)

and my /proc/interrupts (/dev/lp1's irq should be irq7):
           CPU0
  0:     146854          XT-PIC  timer
  1:        724          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  4:        103          XT-PIC  serial
  5:          1          XT-PIC  soundblaster
  8:          2          XT-PIC  rtc
 11:        755          XT-PIC  NE2000
 13:          0          XT-PIC  fpu
 14:      56615          XT-PIC  ide0
 15:          5          XT-PIC  ide1
NMI:          0

and finally, my /etc/printcap:

##PRINTTOOL3## LOCAL uniprint NAxNA a4 {} U_EpsonStylusColor stc500p {}
lp:\
 :sd=/var/spool/lpd/lp:\
 :mx#0:\
 :sh:\
 :lp=/dev/lp1:\
 :if=/var/spool/lpd/lp/filter:

It's not a hardware problem. When Linux initialize the printer during
boot process, it seems ok!

As I need to print my resumes it really annoys me, makes me crazy!
Any ideas please?

This may be *too* obvious, but have you compiled parallel port
support into the kernel? If you made it a module, are you probing/loading
the module?

I had a similar problem.

Try putting this line in /etc/conf.modules

alias parport_lowlevel parport_pc

I then used printool.

#PRINTTOOL3## LOCAL bjc600 360x360 a4 {} BJC600 8 {}
CanonBJC:\
        :sd=/var/spool/lpd/lp:\
        :mx#0:\
        :sh:\
        :lp=/dev/par0:\
        :if=/var/spool/lpd/lp/filter:
##PRINTTOOL3## LOCAL bjc600 360x360 a4 {} BJC600 8 {}
lp:\
        :sd=/var/spool/lpd/lp0:\
        :mx#0:\
        :sh:\
        :lp=/dev/lp0:\
        :if=/var/spool/lpd/lp0/filter:

This enabled me to print from root only, but may get you going. I would
be interest in any improvements to this. I am not logged in as root most
of the time.

That's it!!!!!!!! thank you Brian!

And as mentioned in the /usr/src/linux/xxxxx/parport.txt, I included exactly
these lines in my /etc/conf/modules :

alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7

It works for me, even I'm not root.
Some owner problems?
