I solved the problem with CUPS:

in CUPS you habe to install (http://localhost:631/admin) a printer with driver 
"raw". Name the printer "lp". This driver must be the default printer and the 
first in the row. You will get a file /etc/printcap.cups. Copy this file to 
/etc/printcap. 

In DOSemu you wright:

$_printer = "lp"
$_printer_timeout = (1) # the higher the number, the longer you will wait for 
the output.

If this doesn't work, your CUPS print filter cames in the way. Here the advice

  Hi!
  It seems that print filter corrupts your output.
  Try attached patch for global.conf (it adds '-l' option
  to print command) and run dosemu like this:
  dosemu -F global.conf
