Parallel port scanner in Fedora 16?

[robin108]

Guys, I'm running F16 and trying to connect my Canoscan FB 320p parallel port scanner, but it's not detected.
sane-find-scanner doesn't detect parallel port scanners. I installed xsane and simple-scan, but they don't see the scanner.
I've never used the scanner in Linux before, but I no longer have Windows on the PC, so I need to get it working now. Can anyone help please?

You can instruct sane-find-scanner to probe the parallel port. Did you try that?

sane-find-scanner -p

And the scanner will most likely need to be turned on when you run that command.

Okay, I tried sane-find-scanner -p as suggested. The only change to the output is that it now says "# No Mustek parallel port scanners found." I ran the command as a regular user and also as root, with no luck.

OK. I suppose I should have read the sane-find-scanner man page a little more closely:

sane-find-scanner won't find most parallel port scanners, or scanners connected to proprietary ports. Some parallel
port scanners may be detected by sane-find-scanner -p. At the time of writing this will only detect Mustek parallel
port scanners.

Shows the device (CanoScan FP320P) has some newly added basic support in sane-backends-1.0.22.
and F15 (presumably F16) have this latest set of backends.

If you've installled the package then a
man 5 sane-canon_pp
describes the FP320p interface and configuration.


So you need F15 or F16 (or else this newer sane backends).
You need the sane-backend package.
You need to manually edit the /etc/sane.d/canon_pp.conf file according the the man page above.
I *think* it says that the 620P settings also apply to the 320P.
So the canon_pp.conf file should (I think) contain
FB620P
init_mode FB620P parport0
These lines are in the config file but commented out - so uncomment them.
