I've added a network printer. Both the host and guest are Ubuntu.
The printer added fine, but the system asks for authentication when I try to print. I typed the host's (the account that installed the printer) username/password, didn't work. I typed the guest's username/password, it didn't work either.
What username and password do I enter?
How did you share the printer? There are two methods, one is via samba (windows) and the other is via ipp/cups (unix). As far as I know, cups doesn't require authentication by default unless you've set it up that way. Samba on the other hand does by default.
I would recommend using cups sharing, ipp works in windows clients as well as any other client and is well supported in Ubuntu. You simply go to your
System > Administration > Printing
and selectServer > Settings
.You can then visit the ip address of your server in any web browser at port 631 to check you get a connection and access to the printer:
If you do this, your other machine should see this shared printer automatically. Configuration should then be automatic and you should not have any passwords to deal with.
