Matthew Many thanks for your advice.
I have taken heed of your advice and completed those changes to the canon_pp.conf file and all works sweetly. Tell me though Matthew - is option 2 an option, as such, or can the = changes be made in conjunction with Till's suggestion plus your amendment = (option 1)?

I have then installed/upgraded (Sane Backends 1.0.12-5mdk) - also used the version on the Distro's CDs - and = then Xsane and also tried it the other way around. But each time I get the message 'No Device found' when using 'Normal User' - yet when I use = 'Super User' - bang... in comes Xsane and I am also then able to use Gimp. ... Hi, There are two options to fix this: 1. You can set up saned as Till suggested (this may also yield speed=20 improvements) however, by default the canon_pp backend saves data in=20 the home directory of the user running the program, and saned runs as=20 root, so you may wish to consider changing this line from canon_pp.conf: - calibrate ~/.sane/canon_pp-calibration-pp0 parport0 - to something like this: - calibrate /var/sane/canon_pp-calibration - Leave off the port name too, because there's a bug with the way the = canon_pp backend handles port names from saned. 2. The canon_pp backend uses the correct kernel methods to access the parallel port, however you still need to give your non-super-user = account access. To do this, check the permissions on=20 /dev/parport0 with "ls -l /dev/parport0". On a Debian system it=20 will be something like: - crw-rw---- 1 root lp 99, 0 Jun 15 2002 /dev/parport0 - The letters at the front means that it's a character device, readable = and writable by the owner user, and readable and writable by the owner = group. In this case the owner user is "root" (aka superuser) and owner=20 group is "lp". I assume Mandrake is similar in this respect.. To give your regular user access to this port, you can add yourself to = the "lp" group by typing this at the root (superuser) prompt: - adduser my_normal_username lp - Then if you log out and back in, you will be part of the lp group and = should be able to access the parallel port.
