I'm using the ppd file bundled with cups (/usr/local/share/cups/model/gutenprint/5.1/en_GB/stp-bjc-PIXMA-iP4500.5.1.ppd.gz). > See > http://www.linuxprinting.org/show_printer.cgi?recnum=Canon-PIXMA_IP43 >00_OR_PIXMA_IP4500 > > I'm not sure if just installing the ppd file works.

I couldn't find anywhere to download just the ppd file file so I downloaded cnijfilter-ip4500series_2.80-1_i386.deb from Canon's site and extracted the ppd file from that with tar. That failed with the message "Unable to execute /usr/local/libexec/cups/filter/pstocanonij: No such file or directory". Then I edited the cupsfilter line in the ppd file and replaced pstocanonij with rastertogutenprint.5.1 but that just resulted in "Gutenprint Fatal error: Corrupted NickName attribute in PPD file". The link you quoted implied that the IP4300 driver might also work for the IP4500 so I tried to configure it as an IP4300 but it only spat out a blank page when I tried a test print. Interestingly the CUPS test page (/usr/local/share/cups/data/testprint.ps) only produces the psychedelic rings in the colour wheel if I print it from the local CUPS web page or from KGhostView, if I open it with the gimp and print from there I get the correct colour pattern but with very muddy colours. -- Mike Clarke
