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 Michael
