Hi,

Thanks to Hans, the printing works now. But is terrible slow:

printing a 2.9 MByte Postscript file (containing a bit map, because it
was concerted from a PDF file) gives:

$ ls -l fra.ps
-rw-r--r--  1 guru  wheel  2951274 19 jun 17:44 fra.ps

$ date ; cat fra.ps > /dev/unlpt0 ; date ; cat fra.ps > /dev/ulpt0 ; date
Sat Jun 21 11:43:12 CEST 2014
Sat Jun 21 11:58:48 CEST 2014
Sat Jun 21 12:14:51 CEST 2014

i.e. takes around 15 minutes, regardeless of the used device, 3.2K per
second.

Just for the records
