Print Server Progress Report

Hi all,

anybody interested?

Done:
- abort printing if printer is removed in Printers Prefs
- abort printing when print_server quits
- avoid resource conflicts (=transport add-ons) printing to multiple printers
- print_server detects added or removed printer

Todo:
- restart canceled job
- abort printing if printer add-on fails
- allow Preview print jobs be printed asynchronous
- extension to R5: allow selection of printer per application, similar to Dano
