Printer recognition in yast failed in 12.1

th260 · November 21, 2011, 9:58am

Yast is not able to recognize my Minolta Page Pro 8e connected to LPT1, although the system information shows the correct printer information.

How can I install the printer without yast?

Thanx
Tom

For parallel printers, make sure the ‘lp’ module is loaded. This is no longer done by default. If you need to make it permanent, navigate to

YaST >> System >> /etc/sysconfig Editor >> System >> Kernel >> MODULES_LOADED_ON_BOOT and add the lp driver.

I have done this and rebooted, but no change in behaviour in YAST.

Then try configuring manually. Start your browser, and configure via the CUPS web interface

http://localhost:631/admin

Select ‘Add Printer’, enter username ‘root’, and your root password when prompted. You will get a screen to select your local printer connection, then continue. Follow the prompts given until the configuration is complete.

Then try printing a test page via ‘Printers’ menu. Select the printer (should be listed) >> ‘Maintenance’>> ‘Print Test Page’

When I first use “modprobe lp” as root and start the Yast Printer recognition, everything works perfect.
But after a reboot the lp module seem not to be loaded automatically, although my /etc/sysconfig/kernel includes: MODULES_LOADED_ON_BOOT=“lp”.

How can I manage, that the module is loaded on boot?

I can’t think why that doesn’t work. It might be worth checking that its not blacklisted for some reason (in /etc/modprobe.d/50-blacklist.conf).

Alternatively, you could get it loaded in /etc/init.d/after.local, by adding

modprobe lp

th260 · November 23, 2011, 7:09pm

1.) it is not blacklisted in /etc/modprobe.de/50-blacklist.conf
2.) Adding modprobe lp to /etc/init.d/after.local is also not working!

Maybe it comes too early in the boot process or it is not running?

Thanx
Tom

If you’re using systemd, maybe its not used - I don’t know. Anyway, I guess you can add it to ~/.config/autostart or /home/dean/.kde4/Autostart/ instead (but it only be available to that user account)

Autostart

I use a fresh installation of 12.1, so I think the uses systemd. Anyhow this issue seems to be a bug

Try booting with systemV - boot menu, F5. If this works → bugzilla.

If I boot with system-V the module is loaded as expected. The bug is already listed in bugzilla (https://bugzilla.novell.com/show_bug.cgi?id=732041#c0)

Hello,

I ran into more or less the same problem with HP LaserJet 5MP, which works until now. Today I added module “lp” to MODULES_LOADED_ON_BOOT, and my userid to group “lp” (under User & Groups). Also restarted in System V. I struggled for a while reconfiguring the printer via YAST-Printer, because the test page prints out but regular printing does not work despite these changes.

Finally, I succeeded in both printing modes after these steps, without any change in “lp” settings above:

Delete existing printer and set up another via the command line:


#hp-setup

Switch the permission order or sequence from “deny, allow” to “allow, deny” in /etc/cups/cupsd.conf


#kdesu kwrite /etc/cups/cupsd.conf

Save this file, then restart cups:


#   /etc/init.d/cups restart

deano_ferrari · November 26, 2011, 4:35am

There are a few policies listed there typically. Which one(s) did you need to alter? (Maybe post the entire cupsd.conf).

Thanks. That may be of help to others who come searching.

You are quite welcome, deano.
