Is there any "filter" directive defined in tea4cups.conf ? This could
explain the problem if printing options are embedded in the file.

Otherwise, if you're talking about CUPS options, (lp -o ...), they
should be preserved and passed as-is from CUPS to Tea4CUPS to the real
backend. If they aren't maybe you've hit a bug.

Could you put "LogLevel debug2" and "MaxLogSize 0" in cupsd.conf then
restart CUPS, and put "debug: yes" in tea4cups.conf, then print something,
and send your CUPS' error_log as a gzipped attachment (all lines, not
limited to the Tea4CUPS ones) to me, privately.
