Pixma/CANON TS3451 , FYI
This is only to inform you that:
sane pixma (for CANON) TS3451 Wired USB Works (all the way to 600dpi/color(rgb))
sane escl Wireless WIFI Works only if forced to http(port 80) in /etc/sane.d/escl.conf ,
otherwise xsane (etc) chooses https (which returns error about an 'invalid argument'.
Thank you .
