Printer Setup Repair is designed to rectify situations where the Printer Setup Utility will not open, printers cannot be added, CUPS fails to operate, and numerous other errors. Although Printer Setup Repair cannot fix every printing problem, it is capable of resolving most of the common ones. Printer Setup Repair can also be used to delete unwanted printer drivers, remove a build up of spool files, and recreate the /tmp symbolic link.
