Hello and thanks. Whew, I had just downloaded the sourceforge package...

Done! (I had already read this page and others on your blog, and have
it permanently open in a browser tab. I am amazed by your work here,
thank you so much.)

~/Desktop/mp150-0.14.2-1u$ ./scan -x 10 -y 15 -w 51 -h 25 -1 -d 20 -W
pixmascan.pnm

[lots of stuff snipped, MP710 says on front panel "scan mode"]

[pixma-0.14.2] pixma_close(): Canon MultiPASS MP710

So now I look at the image. Amazing, there is something there, a bit
grainy, but it certainly does work! Tick off another victory for your
[and the oirignal author's] driver and linux! :-)

Now I need to check what quality I can get with the options. Some questions:

1. resolution: -r <number> in the options. What is the suggestion when
the scanner does 1200x2400dpi? Is it possible to specify x and y
resolutions, or must I choose the lowest of the two.  At the moment
the highest resolution I can scan at is apparently 300 (by adding -r
600 to the test as follows):

./scan -x 10 -y 15 -w 51 -h 25 -1 -d 20 -r 300 -W pixmascan_r300.pnm

If I choose 600 it runs for quite a long time giving screen output but
finally cancels with a hardware error. And for 1200 the cancellation
happens quite quickly after starting with screen output.

I hope that information is useful, since I do not know how well the
driver performs on other scanners and with other OSes.

Now I will try to integrate the driver into xsane, and also see how it
does with scanning larger areas up to A4.
Best regards,
