Symptom
When adding a printer in Print Center, you select "Use default queue on server". If this is selected for certain printers, you cannot print to them.
Solution
1. Open Print Center (/Applications/Utilities/).
2. Select the printer's queue.
3. Choose Printer > Delete Printer.
4. Click Add.
5. Select the connection type IP Printing.
6. Enter the printer's IP address or DNS name.
7. Instead of selecting "Use default queue name on server", enter a known good queue for the printer. Refer to your printer's owner's manual for the list of proper IP or LPR queue names.
Note: Most IP printers do not require that a default IP/LPR queue name be specified. However, with printers that have no default queue name specified in firmware, you must correctly specify the queue name to print over IP.
