<p><font size="+1"><font face="Times New Roman">Dear Sir/Madam:</font></font></p>
<p><font size="+1"><font face="Times New Roman"> My system is
Ubuntu 18.04.2 with a new Canon Pixma TS6220, which replaces
an HP Photosmart 6520.<br>
All of the following comments refer to my new Canon
printer. Xsane with my recently retired HP works perfectly
(except, I think the Canon images are the better).<br>
</font></font></p>
<p><font size="+1"><font face="Times New Roman">1) I am able to move
the dashed lines to frame the print to be scanned, but the
output always contains the images of what ever is on the
platen on a "full size" white background.<br>
2) I have selected “inches” as the unit of measurement, but
the preview window has “px” in the upper left corner, and the
dimensions in the windows at the bottom of the main menu are
in pixels. These dimensions do not change as I adjust the
frame of the photo to be scanned and always read 2480*3507*24
(24.9MB).<br>
3) There are no length markings along the side or top of the
preview window.<br>
4) In Advanced Options, the UOM displays “px”. The sliders
change as I adjust the frame, but for a 4” x 6” photo in the
upper left corner, the lower right corner is shown to be
.00235x, .00154y.<br>
5) For all resolutions > 75 ppi, the scanned image of the
photos is very dark/saturated – beyond my ability to correct.<br>
6) Max scan resolution in the main menu is only 300, whereas
it is 1200 with the HP scanner.<br>

<p><font size="+1"><font face="Times New Roman"> This printer is
WiFi equipped, but I am using it with a usb cable as my pc and
printer are on the 2nd floor of our house while the router and
my wife’s pc are on the 1st floor. I am willing to help out in
the testing of your Pixma backend if I can be of any
assistance.<br>
<br>
Kind regards,<br>
