I've used Canon MP810 with CUPS and "IJ Printer Driver" for Linux (supplied by Canon) on FreeBSD. Canon doesn't supply the printer driver for MP810, but I've been able to use the printer with the driver for MP610. These printer specs are very similar. I don't use the printer from FreeBSD so many time, but printing an web page from firefox and the "Print Test Page" from http://localhost:631/ are fine. That color print has no defferences between the Windows's one. So you will be able to use Canon iP4500 (and MP610/MP520/iP3500) with the procedure below . 1. Installng necessary ports 1.1. For the PS to Canon IJ filter print/cups emulators/linux_base-fc4 graphics/linux-jpeg graphics/linux-png graphics/linux-tiff archivers/rpm2cpio 1.2. For compiling the Canon CUPS filter devel/autotools devel/gmake shells/bash 2. Read /usr/ports/print/cups-base/pkg-message, and set some necessary settings. 3. Set the following lines to /etc/rc.conf: linux_enable="YES" cupsd_enable="YES" 4. Download the IJ Printer Driver Ver.2.80 for Linux The following two archives are required: IJ Printer Driver Ver. 2.80 for Linux (rpm Package for iP4500 series) cnijfilter-ip4500series-2.80-1.i386.rpm IJ Printer Driver Ver. 2.80 for Linux (Source file) cnijfilter-common-2.80-1.tar.gz These archives are available at the following sites: Canon Australia - Drivers http://www.canon.com.au/drivers/ Canon Singapore - Support & Download Search http://support-asia.canon-asia.com/ Canon in Japan - "Software Download - Other OSes" (in Japanese) http://cweb.canon.jp/drv-upd/bj/other.html#linux 5. Installing the binary package for iP4500, and a printing test 5.1. Install $ mkdir ip4500 # working directory $ cd ip4500 $ rpm2cpio /PATH/TO/cnijfilter-ip4500series-2.80-1.i386.rpm | cpio -ivd $ su Password: # cp -Ri ./usr /compat/linux/ # /compat/linux/sbin/ldconfig -r /compat/linux 5.2. Printing test (ASCII text) It uses a2ps (ports/print/a2ps-a4). $ su Password: # a2ps -B --borders=no ascii-text.txt | \ gs -q -r600 -dSAFER -dNOPAUSE -dBATCH -sDEVICE=ppmraw -sOutputFile=- - | \ /compat/linux/usr/local/bin/cifip4500 --imageres 600 --media plain > \ /dev/ulpt0 6. Compiling the Canon CUPS filter, and a printing test 6.1. Compile Extract the common source archive, and apply a patch: http://homepage2.nifty.com/dumb_show/unix/cnijfilter-common-2.80-freebsd.diff The patch file is not my original. I got a patch for "Canon Inkjet Print Filter Ver.2.60 for Linux" from http://tabochan.f2g.net/pixus.html (currently the site is down) and modified it for 2.70 and 2.80. Then compile and install the necessary (not all) program. $ mkdir common # working directory $ cd common $ tar zxvf /PATH/TO/cnijfilter-common-2.80-1.tar.gz $ patch < /PATH/TO/cnijfilter-common-2.80-freebsd.diff $ cd cnijfilter-common-2.80/libs $ ./autogen.sh $ gmake $ cd ../pstocanonij $ ./autogen.sh $ gmake $ cd ../ $ su Password: # cp -i pstocanonij/filter/pstocanonij /usr/local/libexec/cups/filter/ # cp -i ppd/*.ppd /usr/local/share/cups/model/ 6.2. Printing test Register the printer. $ su Password: # /usr/local/etc/rc.d/cupsd restart # lpadmin -p PIXUSIP4500 -m canonip4500.ppd -v usb:/dev/ulpt0 -E Finally visit http://localhost:631/ with an web browser, and click "Printers" -> "Print Test Page".
