Printer stopped working suddenly?


Following recurring error from 'error log', what does this mean and what should I do? Thanks

Code:
E [23/Dec/2008:12:01:52 -0600] Unable to set ACLs on root certificate "/var/run/cups/certs/0" - Operation not supported

You have searched for this? A few answers I saw straight off

Try setfacl -m o:rwx /var/run/cups/certs/0

or
vi /etc/selinux/config

SELINUX=disabled

If it's not stopping you printing, I would be slow to worry.

My HP Toolbox no longer recognizes that an HP Printer is installed - yet the printer, scanner, copier all function just perfectly. I have no idea why, and as long as the printer works, I'm not inclineed to investigate it too closely. I'm just a bit lazy at times.

My Canon i550 printer is just a printer and stopped printing.
I don't have a '/etc/selinux/config' file to edit.

Thanks will bookmark your referrals. Can you recommend linux friendly printers? I am looking around linux compatible list and such but there is nothing like personal experienced referrals from people using same linux os. Thanks

A little history here:

Cups can be a bitch when there's not a postscript printer at the other end.
I had this with a cannon bjc - unbelievable problems.

I have an old epson stylus(C70) and I'm fine. I'd actually go for ink cartridge usage. Lexmark, for example have not a good reputation there.

Do i remove old printer references before installing new one?

Am looking at HP and epson models i find listed in open printing db but for now I have an old MFC210 Brother that I am going to try to install.

Question is do I remove the old Canon i550 references first and how do I do that? I know how to remove it from cups html, just not from slackware12, my desktop by the way is xfce. Thanks

USB Printer Settup Questions

Decided to setup MFC210 Brother that was just sitting there, it is a usb printer.
1. Do I uncomment usb printer support or usb hub support to get usb working?
Question arises from USB Support header in /etc/rc.d/rc.modules I think it said that if i uncomment usb hub support then usb devices would automatically be probed for during startup? Did I understand that correctly?
2. Or is it usb parallel support that I had to uncomment?
3. For previous canon parallel printer I had to set my bios to 'parallel port to ECP or EPP', do I have to change my bios now to something else?
4. lpr driver and cups wrapper are .rpm binary pkgs. can I use src2pk to install them without having to convert .rpm?

Thanks this is my first time using any usb device with slackware.

I don't know where you are commenting/uncommenting therefore I won't comment

your printer should appear on /dev/usb/lp0
Connect it, leave it to do it's wake-up routine. Run 'dmesg |tail'. You should get a line or three about it at the bottom. If so, usb is picking it up. Provide feedback on this point

Add and remove your printer through http://localhost:631 with cups running
Provide feedback

you might be left looking for a ppd (=driver) from

business kid, I uncommented USB Support in "/etc/rc.d/rc.modules".
Ran dmesg |tail and there was no /dev/usb/lp0... I i have to install drivers as mentioned in previous post.
Question was did I have to clear out old printer references. Thanks

If this is your first adventure into usb, let me clarify something:

To see it in dmesg|tail or even lsusb (If installed) you need the usb kernel modules for your motherboard installed only. You can check that with lsmod |grep hcd, which should usually show
ehci_hcd
One of uhci_hcd or ohci_hcd

To print a page, you need to set up with drivers in cups, and the kernel modules mentioned above.
