gtkprintoperation: job names must not exceed 255 chars

Browse Source 
According to http://datatracker.ietf.org/doc/rfc2911/, The 'name'
attribute syntax is essentially the same as 'text', including the
REQUIRED support of UTF-8 except that the sequence of characters
is limited so that its encoded form MUST NOT exceed 255 (MAX) octets.

CUPS will not print jobs with names exceeding 255 characters.
