Could not wait. Installed fontconfig etc from incoming. Same error message as before, when trying to print the test page.
Installed cups (all plus dependencies etc) from wheezy. No problem to install with the above fontconfig present. Trying to print: some paper feed and message "Connected to printer", after abt 10 sec the paper is ejected and message "Rendering completed". Log says job is done. Only problem is that the paper is blank. Well, actually there are some faint colored dots, from left: a short horisontal line, three lines in 0, 120 and 240 degrees orientation to each other, and then a strange pattern.
Installed cups etc from sid and also newer version of fontconfig etc and printer-driver-c2esp ver 24.2. Same as above wheezy.
Seems I might have a very long wait?
