Designating the default printer

[Len Zettel]

This is my /etc/printcap file.

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

# Printer name is Laserjet followed by some aliases.
# Header pages suppressed with :sh:
# spooling directory (sd) is /var/spool/lpd/Laserjet
# the line printer device is lpt0
# the input filter (if) is if-simple

-------------------------------------------------------------
If I do lpr -PLaserjet foo
file foo is neatly printed out.

Following Unix Power Tools 43.04, p 790, entering 
PRINTER=Laserjet ; export PRINTER
from a console lets me do 
lpr foo
file foo is printed as above.

Question: What do I put where to specify Laserjet as
the default printer as part of the boot sequence?

thanks
