Jan-Benedikt, thank you for suggestions. I tried your proposal $ stty -F /dev/ttyS1 raw speed 9600 -crtscts cs8 -parenb -cstopb but, unfortunately, without success. But now I know where to dig deeper into the material. I shall read the stty info and I shall fiddle around with the stty settings. Btw. my printer is an old HP-laserjet4P. I don't know, if it accepts plain ASCII, but trying to print a file piped through GHOSTSCRIPT doesn't work either.
