abs@cs.sun.ac.za.

Yes!

   Probably the CR definition of the laserjet isn't setup correctly.
I use an input filter script to set all the correct parameters on the ljet.

here is my /etc/printcap file:
------------------------------ /etc/printcap ----------------------------

#	@(#)printcap	5.3 (Berkeley) 6/30/90

lp|local line printer:\
	:lp=/dev/lpt1:sd=/var/spool/lpd:lf=/var/log/lpd-errs:sh:\
	:if=/usr/local/filters/if_ljet3:\
	:vf=/usr/local/filters/vf_lett3:\
	:df=/usr/local/filters/df_ljet3:
------------------------------------------------------------------------
And this is my homebrew if= input filter script:
( be shure you have the execve magic number patch installed, otherwise
  #!/bin/sh will not work!)
-------------------------- /usr/local/filters/if_ljet3 -----------------

#!/bin/sh
printf "\033E\033&k2G"
cat -
printf "\033E"
--------------------------------------------------------------------------
And here an filter that attempts to print two pages side by side. (use lpr -d)
------------------------- /usr/local/filters/df_ljet3 --------------------

#!/bin/sh
# Page layout variables
LINES=76
TOPMARGIN=5
LEFTMARGIN=0
VMI=5
GUTTER=7
# internal variables: DO NOT CHANGE
width=`expr 162 + 2 \* $GUTTER`
# Reset the printer
printf "\033E"
# set line termination to cr->cr; lf->cr+lf; ff->cr+ff
printf "\033&k2G"
# select landscape orientation
printf "\033&l1O"
# setup the page: vmi, enable perf skip
printf "\033&l${VMI}c1L"
# Top margin TOPMARGIN lines
printf "\033&l${TOPMARGIN}E"
# Text Length $LINES lines
printf "\033&l${LINES}F"
# left margin of LEFTMARGIN chars
printf "\033&a${LEFTMARGIN}L"
# select 16.6 pitch font
printf "\033(s16.6H"
cat - | sed "//d" | pr -2 -n:${GUTTER} -w${width} -e -f -l${LINES}  -v -
printf "\033E"
---------------------------------------------------------------------------

Hope this helps,
