How to remove a printer from the list in the print dialog?
When I go to print something, a dialog showing a list of printer options shows up. One of the printers is from an old office. Firefox spends 20s or so trying to query this printer over the network, and hangs in the meantime. I would like to remove this printer from the list, but have been unable to figure out how to do so. Manually removing all references to the printer from the ~/.mozilla configuration files while firefox isn't running has not helped.
