(Apologies to Olaf - I mistakenly sent a personal reply, and not a forum

After struggling with this a bit, I came across this:

Thankfully (as Thierry pointed out), the Canon D750 quite providentially
reiles on Apple's AirPrint.  Also, running something like 'avahi-browse
--all' will indeed discover the scanner.

When I run 'python scan.py "file.jpg" 500', the scanner is indeed detected,
and everything looks like it's about to work - but I get this error:

urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED]
certificate verify failed (_ssl.c:727)>

Also, when I try to work around this by issuing


and run the script again, I get


Content-Length: 0
Connection: close

Service Unavailable

Also, I tried installing 1.0.28, but I have no clue how to proceed from
there so as to detect and use the scanner. I'm kinda learning all this
little by little :)

Any pointers along either path will be appreciated. Thank you. Regards,

- Brandon
