You need to set up a simple filter program, designated 
via the  :if=/some/path/shellscript  option of
printcap which sends an escape sequence to the deskjet, changing
the way it thinks about CR's and LF's. The one I cobbled together convinces 
the deskjet to look like a simple ascii printer.

echo "^[&k2G"

Look at the docs that come with the lpr daemon source and
also the lpr man pages.  The exit line above is vital.  Also look at
the deskjet's printer escapes - you should find that the 
ESC & k 2 G sequence convinces the deskjet to change its interpretation
of LF's and CR's.   If you really want great things from the deskjet, 
you might want to install ghostscript.  Some earlier posts to this list
covered this.

Good luck,
