[winswitch] Unable to print from the GTK2 client

[Eric Grammatico]

hi there,

I tried to setup xpra with printing feature. Unfortunately, I met an error with the GTK2 client. The xpra server is running with CUPS, and the xpra client and the xapp (libreoffice) are running on remote hosts.

The printers are shared as awaited, and visible from xapp host. No error, no message from the Xapp when printing, but xpra server and xpra client raise errors in their respective logs.

the error stack from xpra server:
parsed printer options: {'sha1': 'c3576dac636aa5936be2265728db719be87b74c9', 'printer': 'Xerox_Phaser_3250', 'options': {'time-at-processing': '1476885259', 'time-at-creation': '1476885259', 'job-originating-host-name': '172.19.0.3', 'PageSize': 'A4', 'job-uuid': 'urn:uuid:8969ba04-18ed-3bf4-5b5f-6d4619a262de'}, 'copies': '1', 'title': 'Untitled1'}
