Thank you for the hint. In current Debian (unstable/experimental) and Ubuntu cpdftocps is replaced by a new pdftops filter (part of the cups-filters package, maintained upstream by me) which takes over both the role of the old pdftops filter and of the cpdftocps filter. It is written in C and by configuration settings or print job options one can make it use either Ghostscript or Poppler. Currently, Ghostscript is the default and so the problem described here should not occur. In the future I intend continuing Ghostscript for desktop and server use but switching to Poppler for mobile devices. In this case the problem could reappear and I would need to add the equivalent of "grep -v 'Policies 1 dict dup begin .PageSize 3 def end def'" to the pdftops filter. Now I have tested with the current Poppler on Ubuntu Raring and found out that instead of Policies 1 dict dup begin .PageSize 3 def end def I get /Policies 1 dict dup begin /PageSize 6 def end def and I am in doubt of whether I have to remove this now to get compatible with Brother printers. So I want to ask you to do some testing: 1. On Ubuntu Raring (you can boot it with a live CD) or Debian Experimental try a. Set up your printer and print normally. Does it work? b. Make sure your print queue uses your Brother printer in PostScript mode. Correct the queue's configuration if needed and re-test. c. Print a job with the command line lp -d <printer> -o pdftops-renderer=pdftops <file> Does it still work correctly? 2. In your normal environment do the following: pdftops <PDF file> This produces a PS file containing the line /Policies 1 dict dup begin .PageSize 3 def end def Replace the line by /Policies 1 dict dup begin /PageSize 6 def end def with a text editor. Replace all occurences of the line. Then print the file unfiltered: lp -o raw <PS file> Does it come out correctly?
