Cups for large number of printers

However, there are things that don't scale well. E.g. browsing servers from MacOS X can take quite some time when there are 500 printers. Also, GUI's are not generally adapted to such a large number of printers as there is no way to specify sort order e.g. putting favorite printers on top of the list or group selections.

More of this stuff Bse ?
