Once, the printer on the print server is broken. After repairing, then connect it, other machines can no longer connect to the printer, prompt "The printer is incorrect". If you can't take a while, you can restart the "Print Spooler" service. Later, I thought that something that may be the ID of the original printer in the registry did not refresh, and it is estimated that the restart machine can also solve the problem. I haven't tried it. Who will try it, tell me the results.
