Interesting.  IF scangearmp2 needs SANE, then why can it work without 
SANE being installed?

I just checked for it. It was not installed.  I installed SANE and it 
scangearmp2 did not work any different.  Still, LO "media scan" option 
does not work either.

Actually, I have scangearmp2 as a launcher on my desktop. Since it shows 
a GUI window when called, it is not fully command line with all of the 
options as parts of the command.  I wish the "2" version had all the 
options that the original one had.  At least it saves JPG instead of 
just PNG.


"use with Linux" is something I do search for.
I do so by looking for printers that have Linux drivers coming from the 
manufacturer, and not a third party.  For Canon, all 4 of the printers 
had drivers for DEB based Linux. Usually, I have to go to the Canon UK 
site for the drivers.  This last one, TS9020, was the first one that had 
Linux drivers in the USA site. I found out how much the problem was when 
I had an Epson Workflow[?] printer.  I could print OK, except for 
duplexing.  It would not scan at all till I installed Ubuntu 12.04.  I 
started out with 9.10 on that desktop.

The only printer brand that I get the drivers from a "3rd party" is HP. 
They are the easiest to get the drivers, etc.. It seems that their Open 
Source driver system will "make" a driver for the specific OS and model 
you have.

The first 3 Canon PIXMA models I had used used scangearmp.  This new one 
required "scangearmp2" the newer version -  Scan Gear MP 3.40. The old 
and new one are not compatible, backwards or forward.

So, "linux-hostile" is not as true as people think.  Sure, till now, 
Canon's support system tells you that they do not support Linux. This 
was for the USA support system.  If you went to the UK support site, you 
can find the Linux drivers there.  Sure, when I bought a Pixma MG6220, I 
had to get the MG6240 driver - since it was called MG6200 driver. So I 
could buy the Canon printer and get the drivers for Linux.

Also, I make sure I can get third party ink.  I cannot afford the Canon 
OEM pricing.  When I had the MG6220, I could get 6+ full sets of ink for 
the same price I would get for 1 OEM set.  This new TS9220 set costs 
more, but the printer has not been out as long as the others.  It is 
getting lower in costs though. I can use a lot of ink each month, if I 
am doing a lot of "work".  So, ink costs are very important for someone 
on a fixed [mostly] income.
