printcap help please

["Steve Brown" <steve@he.net>]

Starting with the slink base system, I installed packages lprng, 
magicfilter, gs. Then did  magicfilterconfig --force

I ended up with the following in /etc/printcap

lp|hpdj|HP Deskjet540:\
	:lp=/dev/lp0:sd=/var/spool/lpd/hpdj:\
	:sh:pw#80:pl#66:px#1440:mx#0:\
	:if=/etc/magicfilter/dj500-filter:\
	:af=/var/log/lp-acct:lf=/var/log/lp-errs:

I know /dev/lp0 is correct because I've gotten 
output there for example with   ls >  /dev/lp0.
But when I try lpq or lpr I get 

no printcap for printer 'lp'

and the lpr attempt also says "transfer to 
lp@localhost failed"

What's wrong with the file?

thanks,

Steve
