Comment 5 for bug 302158

Part 1, what led up to the issue:
*****
Brother HL-2140 printer was detected/automatically added

For any print job, printer would repeatedly print blank pages. (eg, 1 job, 1 page, results in continuous blank pages being printed)

I read that it was likely fix to change the "Make and Model" driver from "Brother HL-2140 Foomatic/Postscript [en] (recommended)" (yeah right, "recommended") to "Brother HL-2140 Foomatic/hl1250 [en]"

Instead of trying to see if that worked, I also read about a Brother lpr and cups packages, so opted to go that path.

At this point, I had NOT encountered this original old bug when I changed the DPI and economy toner settings.

Part 2, using Brother packages
*****
Deleted printer and turned off the printer

Prerequisites: http://support.brother.com/g/s/id/linux/en/before.html?c=us&lang=en&prod=hl2140_all&redirect=on
Packages: http://support.brother.com/g/b/downloadlist.aspx?c=us&lang=en&prod=hl2140_all&os=128

After performing the prerequisites and installing, I turned printer on and "2" printers were automatically created. One was the original (usb://Brother/HL-2140%20series?serial=<sanitized>) which was "Set as Default", the other was (usb:/dev/usb/lp0).

Knowing the original printer was flawed, I TRIED to "Set as Default" the lp0 printer leaving it as "Set as the system-wide default printer"
THIS prompted for the password. It still would set it as the default, but since I'm the only user, I don't know if it was truly "system-wide".

Changing the default printer back did NOT prompt for any password. Going back again to lp0 DID NOT at some point with multiple tries. Then changing the "Job Options" prompted again.

I think among the multiple tries, I had added myself to the "lpadmin" group (only sudo and myself were the other groups), and that would work.
