Hello Sanjoy; thank you for your detailed report. Time has moved on and I am using cups 1.7.5-11 and cups-filters 1.0.61-5 to repeat your tests.

You are sending PostScript to a PostScript printer and for some time now the only filter which should be used is pstops. An explanation for this behaviour is at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=712237 > I made a print-to-file queue with: > > lpadmin -p test -E -v file:/tmp/printout -P /etc/cups/ppd/lj400.ppd > > and printed to it with > > lp -d test -o PageSize=Letter -o scaling=50 > /usr/share/hplip/data/ps/testpage.ps.gz > > I've attached /tmp/printout and lj400.ppd. > > You can see (with gv, after taking out the jcl wrapper) that the ps part > of the file is full sized (not shrunk). > > I see the same problem with a HP PSC 2700 and with a CUPS PDF print > queue.

I too observe no scaling. pstops is an upstream cups file so it would be reasonable to assume the comments in "Image Options" at http://localhost:631/help/options.html apply. fitplot is fit-to-page nowadays. /usr/sbin/cupsfilter -m appliaction/vnd.cups-postscript -p lj400.ppd -o fit-to-page -o PageSize=A4 testpage.ps.gz > out.ps gives me out.ps which I can send to my PS printer with "-o raw". It prints perfectly. Since Wheezy pdftopdf has changed and fit-to-page and scaling are not handled by that filter in quite the same way now. But pdftopdf is not invoked with lj400.ppd. I did not test with the HP PSC 2700 because I could not find it. Regards, Brian. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
