Knoppix 7.0 requires modification of Canon Printer Driver .deb packages

[johnmd]

Hi Everyone
The printer driver packages I downloaded from Canon for my Canon Pixma mp190 multifunction which have worked fine since Knoppix 6.0.1 -see post below

http://knoppix.net/forum/threads/27635-6-things-about-knoppix-6.0.1-i-wish-i-d-known-yesterday

no longer work in Knoppix 7.0 because it now uses the package libcups2 instead of libcupsys2. After some googling I found this post that seemed to offer a DIY solution

http://www.teachmejoomla.net/code/linux/canon-scanner-fixing-permission-denied-with-udev-rule.html

This post gives the general idea of what to do.

But in fact it doesn't work on debian/knoppix 7.0 because there is no <deb> command available and archive-manager/file-roller will only open an archive read only [even when run as root] - but what does work is to extract cnijfilter-common####.deb with the command


file-roller --extract-to=./cnijfilter-common cnijfilter-common_3.00-1_i386.deb

[answering yes to the question of whether to create the folder as it does not yet exist]


then go into created folder <cnijfilter-common> and open the file /Debian/control with gedit [as root] and change the entry under line 'requires' from


libcupsys2 to libcups2 - [inserting in the approprate version details for your libcups2 package]


save the changes and then put the .deb package back together again with


dpkg-deb --build cnijfilter-mp190 cnijfilter-mp190.deb


giving it a new name - [which doesn't have to obey all the complex debian package/version nameing rules if you are only doing it for your own immediate use]


then install your new package


dpkg -i cnijfilter-common.deb


and repeat the whole process with the cnijfilter-mp190#####.deb package and install that too


then go to preferences | printer configuration and modify the settings again to change the driver to the one you've just installed


The scangear-common####.deb and scangear-mp190####.deb packages will install fine just as they are, without playing around with them [on my ageing Compaq desktop, anyway].

I doubt if such a simple fix will work in many cases of dependency conflict but it does work in this case. I hope it will help other people too.


Best wishes, John

Hi Johnmd,
I use every day Canon MP190 with knoppix 6.7.1
I use the default driver of knoppix: choose Canon PIXMA MP180 with CUPS and Gutenprint
It works great

I have yet to try with knoppix 7 when will be available
Bye

Hi Blacksimon
Thank you. I'll remember that in future. I'm sure you are right. I've just got in a bit of a rut with installing the Canon Driver version. It's so long ago now that i started doing this, (maybe back to v6.0) that I'm not sure exactly, but I have a memory of colour printing not giving the true colours with the standard Gutenprint MP180 driver. But by now, maybe the Gutenprint Driver has changed too. It's certainly much easier to just use the Gutenprint one that comes already to use with Knoppix.
Best wishes, John
