So, I've got a problem I've been unable to solve. In our offices we have 3 Macs set, and several Windows machines. We have enabled account track on our Konica Minolta bizhub c360 printer/copier. All Windows machines can print fine. It's a network printer on a Windows based server so no problem there. I have the correct drivers from the Konica Minolta website in case of this iMac, 3.0.8_3.1.0 it's running Mac OSX 10.5.8. I have set up account track when trying to pring via the Output Method drop down menu via Word for Mac. We have user authentication disabled. I can login to the printer's interface via it's IP address and print a PDF file, or XPS file directly that way. When I try to print any document, keychain pops up asking me for a username and password to print to the printer. It should not require a username, only a password for account track purposes. I cannot leave the username blank. I have tried every combination (password in both fields, account the name is registered under, the number of the account, network login, etc) I can think of to let it pass authentication, but it never does. We have the copier via a local company on contract and the service technician couldn't figure it out. I've searched the internet and have had no luck thus far. Any help regarding this issue would be appreciated. Thanks.
