I have been able to get my Pixma MP600R to work with xsane over the wlan at various times before, but after upgrading to the latest ubuntu recently I can't get it to work anymore.
I've pulled the latest git sources for sane-backend and built and installed it: $ scanimage -V scanimage (sane-backends) 1.0.24git; backend version 1.0.24 The scanner is usually detected fine (although usually at the second attempt): $ scanimage -L device `pixma:MP600R_printer' is a CANON Canon PIXMA MP600R multi-function peripheral However any actual scanning always fails, apparently the scanner reports 0 bytes available at some point, and then there's no progress from there on. Any clues? $ SANE_DEBUG_PIXMA=12 scanimage -T [sanei_debug] Setting debug level of pixma to 12. [pixma] pixma is compiled without pthread support.
