That's simple !
All you need to do is send the following sequence to your printer
at the beginning of each print job: "\033&k2G".
It works with all Laserjet Printers since at least the Laserjet 1+
and with all other HP-PCL printers (ie. Deskjet, newer Paintjet) ...
We do this with the following output filter (install mode 0755):
-- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --
#!/bin/sh
########################################################################
# Output Filter for HP PCL Printer
#
# reset plotter, select LF->CRLF mode
INIT="\033E\033&k2G\c"
# reset plotter
UNINIT="\033E\c"
echo -e $INIT
cat
echo -e $UNINIT
# signal success
exit 0
-- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --- 8< --
This filter gets invoked by adding the following 'printcap' entries:
:if=/vol/local/lib/lpdfilters/HP-PCL:\
:sh:\
:tr=:
This allows sending an unmodified data stream to the printer (ie. no
LF->CRLF substitution in the output filter, which would corrupt binary
data (graphics) and fonts).

No, definitely not ...
