hi there,
am using canon pixma mg2270 multi function printer. using the official canon driver for linux mg2200 series v3.80.
could scan/print under linux without problem
however for scanning the file size is much much larger compared with using under windows.
e.g. scanning a color document
under windows - default settings 300 dpi, a4 size, color, file size is ~1mb.
under linux - adjust to similar settings, 300 dpi, a4 size, color, file size is ~6mb.
and the linux scan output quality is just similar with windows scan, if not worse.
anyone having a clue? any settings to adjust? thanks.

If the file is .png, the size should be about the same, if the
compression ratio is the same on both sides. If the file is .jpg, the
difference can be even larger.
Even if you are scanning to PDF, the images are (or may be?) compressed
using jpg, so the size variance can be large as well.
It is very difficult to do a meaningful comparison.

The Canon scanner driver (backend) and scangearmp (frontend) are proprietary, so unlikely to be openSUSE-specific really. You need to take any issues up with Canon yourself. (Most other brands utilize standard sane libraries and therefore can work with other Linux scanning applications such as simple-scan, kooka, or xsane). Have you optimized the settings in ‘Advanced Mode’? You didn’t mention which file format you are saving the image as?
According to this blog, it should be possible to scan via the gimp application (which has far more options to process the and compress the scanned image).
You can launch the app from the terminal by typing scangearmp and it is also available within Gimp by selecting File, Create,** Scan Gear MP…**
