Subject: [PATCH] Add remote print queue support
|
|
|
|
Cups servers which announce themselves on avahi will be shown in
|
|
the printer dialog. This adds a delay the first time the print dialog
|
|
is opened in order to search for print queues . If you don't have any
|
|
network printer queue and you find the delay too annoying, it can be
|
|
disabled by setting the QT_DISABLE_PRINTER_DISCOVERY environment variable
|
|
to 1
|
|
|
|
