Configuring Canon IR-ADV printer in Manjaro

Staring a new job I needed a new OS and decided to go with Manjaro so as not to have to try to remember how to install Arch again.
Everything is mostly great, but I installed the Canon CQUE driver software and it seemed to see the printer next door but when I tried to use it I would get error codes or nothing at all.
I figured out I needed to use the UFR II drivers instead (whatever that is) which I discovered by looking for a driver in Windows (which worked). So in Manjaro I removed the cque driver and used

yay -S cndrvcups-lb

to install the different drivers (which don't use PCL/PS/whatever) I then reinstalled the printer using the new driver and everything is good!

rename command in Arch

I couldn't figure out why my rename command wasn't working in Arch, and it slowly dawned on me that the rename command in Arch doesn't support regular expressions... making it almost completely useless.
After some searching I found this blog entry that confirmed my suspicions and pointed me to an AUR package that basically implements rename with regular expressions.

$ packer -S rename

$ renamexm -s/\ /_/g *

Replace spaces with underscores in all files.

Arch bluetooth connections fixed?

I have been having issues with bluetooth connections since I switched to Arch. I ran "journalctl" and saw an entry "Unable to connect to SEP" which led me to http://en.gentoo-wiki.com/wiki/Bluetooth_headset#Troubleshooting

After adding

  [General]
  Enable=Socket

to /etc/bluetooth/audio.conf my bluetooth speaker connected right away. Hope it stays fixed.

EDIT: This worked as I said, but a day or two later I was having the issue again and eventually found a message indicating a socket error (I don't remember exactly what it was). I undid this modification and haven't had any trouble since, so... who knows.
