So... I reinstalled Arch yesterday, and have tripped up on a CUPS problem. Funny thing is, I had Arch installed before, but after the CUPS 1.4 upgrade and didn't have this problem back then.
Anyway, I was trying to install by USB Printer (Brother HL 1440) via the web interface. Basically, Administration -> Find New Printers. It says, "No printers found."
Being an experienced trouble-shooter, I looked at the CUPS wiki and various forum threads to try to solve the problems. Despite my thorough compliance with all instructions, CUPS still doesn't find my printer.
Firstly, I have these packages installed along with their dependencies (obviously):
* cups
* gutenprint
* foomatic-db-engine
* foomatic-filters
* foomatic-db-nonfree
Secondly, I have blacklisted usblp and made sure it isn't loaded:
$ lsmod | grep usblp
$Thirdly, I have the correct permissions set for the usb dev via the appropriate udev rule, as suggested in the cups wiki:
$ lsusb

crw-rw---- 1 root lp 189, 643 2009-11-07 12:02 /dev/bus/usb/006/004
$I have tried restarting cups daemon, checked that it is in my DAEMONS list in rc.conf, and rebooted my computer. My username is also in the lp group.
I've also checked the /var/log/cups/error.log file, and found nothing particularly extraordinary except this line:
Unable to set ACLs on root certificate "/var/run/cups/certs/0" - Operation not supportedI'm not sure if that line is really relevant.
Could anyone please suggest some solutions to this?
------------------------------
EDIT:
I've just realised that the web interface shows my CUPS version as 1.3.11!!!!! My system is fully up to date (I've done pacman -Syy and -Syu). Shouldn't the CUPS version be 1.4.1?

OK, got it figured.
It looks like CUPS 1.3 is on my system, not 1.4. I can't understand why this is, since 1.4 was released several weeks ago and as I mentioned earlier, my system is fully up-to-date.
I'm using the usblp module for the time being. When or if CUPS is updated 1.4, I'll just have to remember to unload it.
What a strange problem.
