Hi!
cupsfilters 1.0.7 include a fix for Brother printers to workaround a
bug in the Postscript interpreter:
- pdftops: Additional workaround for a bug in the PostsSript interpreters
of Brother printers, calling Ghostscript with special command line
options (LP: #955553).
Unfortunately, this fix relies on a patch in Ghostscript which is not
applied in Debian. Please, apply it.
Thanks.
