When using a non C locale such as fr_FR.ISO8859-1, the CUPS messages
returned by lpq are translated. However, the parser in ParseJobs.C can only
handle messages in English. As a result, dtprintinfo exits immediately with
an error message. To fix that problem we force a LANG=C environment when calling
lpq so that messages will be in English and will be processed correctly by dtprintinfo
parser.
Use /usr/local/bin/lpq from CUPS for FreeBSD
for now; this prevents immediate dtprintinfo
crash.
In the future we should handle both built-in
/usr/bin/lpq as well as CUPS /usr/local/bin/lpq
output in separate functions.
Code to support CUPS should probably shared between
other operating systems.
