[sane-devel] On a clear day... You can see my scanner! (Edited from my business email)

[Matthew Duggan]

Hi Steven,

The N340P support in SANE has been stable for many versions of sane, so getting a newer version compiling won't make any difference.  I'd recommend just using the packaged Ubuntu version, as it will have all the dependencies you need already configured.

SANE doesn't include any drivers for parallel ports, that's left up to the Linux kernel module "parport" (and ppdev, and parport_pc).  If you can't get those drivers to recognise your parallel port, then there's nothing that SANE can do to access it.  I'm not familiar with the recommended way to set up the parallel port driver modules in Ubuntu, I'm sure some googling will help.  The old-fashioned way was to add it to /etc/modules or use "modprobe" from the command-line.

Once you get your parallel port is recognised by linux, then SANE should be able to work with the scanner.

Kind Regards,

Matthew Duggan
canon_pp maintainer.. I guess.

I have used several versions of Ubuntu over the last few years and must admit that since switching to Linux from windows writing code sometimes leaves me clueless. However, Linux is far too good to pass up and return to the nightmare of restrictions that windows offers in its licences. My problem is that only half of my computer wants to see my scanner. This is a CanoScan N340P making it a parallel port version. (Some how thinking in retrospect that USB would have been better at the time!) My version of Ubuntu is Hardy heron... at one time this year I was up to date with Jaunty Jackalope but ran into some serious bugs which is of course another story! Anyway, My version of Hardy has wine installed and just to make things a little more confusing my computer is dual boot with an old windows program that I use for the things wine won't run. Now, My version of wine is pretty good as it has Direct X, Microsoft .Net and a few other programs in it.

I installed the current version of Sane 1.0.19 from the Ubuntu repository along with the extras package for good measure, but no joy. Given that I have wine emulating XP and a whole host of goodies in there, I added the Canon software since I have been to the internet using wine before among other things. However it just thinks about it, then throws the error code "0x00070800" back at me telling me it couldn't find it. In frustration, I added the device manager to my system tools to see if I could find the problem. I noticed an unknown device listed, but try as I may can't find out what it is. It reports as a serial platform device 8250 but that is as far as it got. I decided to replace my version of Sane with a more up to date stable version and have another go with Linux. I downloaded Sane 1.0.20 and as of this afternoon spent most of it after reading both the install instructions and the readme, to install it. Alas I admit I am not good with computer code even though I have had some limited success in the past installing using the terminal! Adobe Reader, Real Player and a few others show that some times things do work the way they are intended. This afternoon however was not one of them... I copied the text below from the terminal which seems to tell me that something is missing from the tar. Try as I may I got no joy at all and a pair of tired sore eyes for my trouble.
