Danny,
A few thoughts...
+“This model that I used in my office. worked there but I had a professional set it up (not me!).”+
So it may have been setup as a network printer vs. your present direct USB connection. Might be an old preference file on your computer. Don't worry about that for now...
Afício is the product name for the South America market as shown on the cover of the manual. See

Of the three choices try Aficio 1515MF
As Matt surmised, you may be missing the PPD file or your computer has it but does not recognize it. Try launching Disk Utility (in the Utilities folder), select your disk in the left pane, click on the First Aid tab and then click on the Repair Disk Permissions button. Afterwards, try printing.
If the problem persists, try downloading and installing the PPD and Printer Utility for Mac (updated version on 4/9/2009) from Lanier (

Reboot computer, repair disk permissions, launch Printer Setup Utility, delete the previous printers, Add printer and then try printing.
One more thing, are you really using OS 10.4.1? If yes, update to 10.4.

Hope this helps.
