Cups is always asking for password when printing on a certain printer
30,645
Since you say it's only one printer which is showing this behaviour, the error is likely to be in /etc/cups/printers.conf
.
Check the authorization entry for the printer which is asking for passwords.

When I send print to a network printer (HP Laserjet 2200d), CUPS asks for username/password. It doesn't happen with other printers and I'm sure its a CUPS issue, because it's asking the password even if I'm not connected to the network.
Here is my
/etc/cups/cupsd.conf
:# # # Sample configuration file for the CUPS scheduler. See "man cupsd.conf" for a # complete description of this file. # # Log general information in error_log - change "warn" to "debug" # for troubleshooting...

StarNamer almost 12 yearsSince you say it's only one printer which is showing this behaviour, can you post
/etc/cups/printers.conf
since the error is likely to be in a parameter for just that printer. -
jasmines almost 12 yearsYou won! I've changed the authorization line in that file and all went ok! If you want, you can answer and I'll approve.
