 |
|
I just installed Gentoo with parallel support compiled into the kernel. I was trying to configure cups and Gentoo will not see /dev/lp0. Here is the dmesg after boot which shows my parallel port was detected
| Code: |
devfs: v1.12c (20020818) Richard Gooch (rgooch@atnf.csiro.au)
devfs: boot_options: 0x1
Installing knfsd (copyright (C) 1996 okir@monad.swb.de).
parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE]
parport0: irq 7 detected
parport0: Printer, HEWLETT-PACKARD DESKJET 950C
|
Now I noticed it sees the port as parport0. Is there a way to alias it to /dev/lp0. That is the device that all the KDE printer programs need including cups. Or is there something I am doing wrong?
Thanks |

In my dmesg, in addition to two parport lines like you have there is a line:
| Code: | | lp0: using parport0 (polling). |
Do you have one of those?
Also, is /dev/lp0 totally absent on your computer or can it just not read the device correctly? /dev/lp0 should be a symlink to /dev/printers/0.
do an "ls -l /dev/lp0" to see if it is the correct link.
If the device files do not exist on your box, you can see if this fixes it:
| Code: | su
cd /dev
./MAKEDEV lp |
This should make the correct device files and links.
Alternatively you can try:
| Code: | | ln -s /dev/printers/0 /dev/lp0 |
which should create the symbolic link you need. I'm not sure, but there might be more to it than that though.
Once the device files are setup, you can configure cups by running as root and doing "lynx 127.0.0.1:631" or whatever browser you want instead of lynx.
then test it all with "lpr sometext.txt"
Hope that helps.

Nope all it says is whats in the above dmesg. When I try to configure the printer in cups kde. It shows the printer, but on the url to the device it shows /dev/unknown-parrallel0 or something like that. If I try to change it it doesn't work. If I leave it cups works fine but nothing goes to my printer. I was noticing that some things work better as modules. I was thinking of recompiling as modules. If I do what are the module names I have to load in order to get lp0. Also, I tried what you said. It added an lp0 to my /dev directory, but still the same problem. Also upon looking at my /dev directory, I don't have a /dev/printers/0 device listed.
Also, I noticed in my menuconfig when making my kernel under parralel support there is no printer option. Is that accurate?
Thanks for the help so far, any more help would be greatly appreciated. One of the things I love about gentoo is the user comunity!
Thanks |

This may help, under 'character devices' in the kernel config, try enabeling 'Parallel printer support' I have it as a module, and when that is done the module is called 'lp' load that and you should produce a lp0 entry in /dev.
Let me know if you need anymore help.
