[ CC Rolf ] Hi,
I tried to contact the maintainer of the Ubuntu PPA which offers support for Canon Pixma series in [2]. I got my email back - domain seems not to exist or temporarily not available. So, I fell over sane-devel mailing-list and read some threads (Rolf seems to be active user what concerns Canon supported devices). There exist a Linux 64bit driver from Canon (see [1]) - unsure if this supports only the printer part. I am highly interested in getting the scanner run under Ubuntu/bionic and/or Debian/testing AMD64. Last, I fell over sane-backends and the debian Git repository. My questions: Can you give a status and maybe a brief intro on how to install and test SANE backend drivers for a Canon Pixma TR8550? Also point me to recent development in Git if salsa.d.o has not the latest stuff. If you need further informations please let me know. I am glad if I can help. Thanks.
