Printer all of sudden not recognized

[Aaron]

When i first got my new computer with windows Vista I plugged my printer in
a Bam! we are printing. Now , 2 months later when I go to print nothing
happens and when I check "find printer" it says " the active directory domain
services are currently unavailable." I have tried reinstalling, rebooting,
setting up a new usb port to no avail. What the heck has happened?

Also, this is just a stand alone computer ,not a network.
