cups usb printer, udev permissions, wiki

Hi,

I just had a problem with my usb printer not being recognized by cups. Probably this was due to a kernel update or something similar (can't say for sure). The problem was easily resolved by having udev set device permissions to group lp.
/etc/udev/rules.d/23-usb-printer.rules:

# Kyocera Mita FS-1020D
ATTR{idVendor}=="0482", ATTR{idProduct}=="000e", MODE:="0664", GROUP:="lp"

After re-plugging the printer CUPS detected it as expected.

This problem is already described here:
https://bbs.archlinux.org/viewtopic.php?id=82489

However, there is no mentioning of this in
https://wiki.archlinux.org/index.php/Cups#USB_printers

Shouldn't this be added to the wiki?

It took me a while to come up with the solution above. Google searches like
https://www.google.de/search?q=linux+cu … sb+printer
give misleading results, e.g. blacklisting usblp.
So, it seems like many other people could have a hard time finding a solution to this problem, which I presume to be pretty common.

Is the solution (to add a udev rule) the right thing to do [tm]? What are other distributions doing?

If this is general, please edit the wiki with the steps.  After all, the wiki is user supported and maintained.

No this is not general.
The latest udev has the rules in the correct order for recognising printers.
I personaly have only 1 rule in /etc/udev/rules.d wich has to do with a bluetooth adapter.
I don't know where you got that rule from but in the current systemd(udev) there is no rule : 23-usb-printer.rules
My printer is correctly detected and my scanner works. (Brother MFC210C)
My advice would be to remove that rule from /etc/udev/rules, and check that you have the latest systemd.
