I saw this problem recently too. Printing through mousepad brings up the xfprint4 dialog (the same as calling "xfprint4" from command line) but then get error "client-error-bad-request".
A workaround is to then call xfprint4 directly from CLI. But this produces a more serious bug: the original text file that is printed gets deleted. In my case, I am printing through cups to cups-pdf. -- mousepad doesn´t print https://launchpad.net/bugs/41271 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
