I am using OpenWRT 14.07, with CUPS 1.5.4. When I try to add a printer, the UI leads me through the entire workflow, until I get to the end. At the end of the workflow, after I have found the printer, added descriptions, specified drivers, etc. I click on "Add Printer".
At this point the CUPS admin UI sends me a Basic Auth request asking for a username and pasword in the"CUPS" realm :
A username and password are being requested by http://192.168.0.1:631. The site says: "CUPS"
I can not get the admin site to accept any username/password combination. I had seen this before on different screens and entered "root"/"password" and the UI had accepted it there. I've played around with the setting since then, and now the only time I get prompted for a username and password is when I click on "Add Printer".
I tried to add the printer manually by directly editing the "printers.conf" (against advice and out of desperation). Now the printer appears, but jobs just disappear. (I assume that the advice was cogent and some queue setup step did not occur) The "manual printer behavior may be a different question, but the applicable observation here is that "Modify Printer" now has the same password behavior.
I am new to CUPS (at this level) and OpenWRT, but I have been using linux for 15-20 years, both personally and professionally in both PC and embedded environments.
Any help is appreciated. My configurations are attached. I've been mangling them to try to get around this issue for a while.
