No parallel printer with udev

Am I right in thinking this is an outstanding area where udev development is concerned?

regards

My parallel printer works fine with udev. I had no problems installing it (lexmark optra R+).

It needs to be configured in two different places in the kernel config.
Device Drivers > Parallel Port Support and
Device Drivers > Character Devices > Parallel Printer Support

same deal here:

ps ax shows the whole filter shebang being fired off, then hpijs just sits and
waits for the device to become active.

cups manage printers still *lists* parallel as an option, but assigns it
/dev/unknown-parallel0 as a device name

/dev/lp0, /dev/lp1, /dev/lp2 exist, as well as /dev/par0, /dev/par1, /dev/par2,
but none of these work as printer devices (killing cupsd each time, reconfigure
printer in cups, hand-edit printer.conf, restart cupsd)

lsmod shows (coldplug) parport_pc & parport loaded.

kernel 2.6.9-r9 + ali3nx bootstrap

ok. after looking around dogpile a bit, i set all the above-mentioned config
lines to 'compiled-in', as opposed to 'modules'.

this causes lp0 to load at boot time, bypassing the udev coldplug, giving
me a /dev/lp0 that's only usable via lpr, so far.

am currently trying to get eg gs to recognize the port, as a postscript device.

this is 2.6.9-r9 dev-sources w/ 2.6 headers and nptl.

cheers

Thanks for the info headgap

I'll try that and hope to get /dev/lp0 back.

Only way I can print at the moment is to move a copy of lp0, which I made with 'mknod lp0 c 6 0', into /dev then it all springs to life and prints whats stuck waiting in the jobs queue.

yes, well i've been able to kludge postscript support using the time-honoured

ln -sf ljetplus lp0 # some convenient gs-supported device name
gs -sDEVICE=ljetplus -sOutputFile=\|lpr <some ps or pdf file>

where ps ax then shows gs having spawned lpr, and shortly the output
appears

mozilla no such luck :(

cheers

nb: but one shouldn't have to go through hoops like this...

Happy to report that /dev/lp0 comes up as you indicated and my parallel printer is working again... yes! :-D

Tho' I thought udev should make a folder called /dev/printers

thanks
