Hi Malcolm,

Yes.  There are many lines there similar to printer self-testing

Only one line then the page eject.

Where can I config/add 'CR-LF'

No it continued to run until I removed all papers from the printer tray.

/etc/printcap
HPDJ690C|cdj670;r=300x300;q=medium;c=full;p=a4;m=auto:\
    :lp=/dev/lpt0:\
    :if=/usr/local/etc/apsfilter/basedir/bin/apsfilter:\
    :sd=/var/spool/lpd/HPDJ690C:\
    :lf=/var/spool/lpd/HPDJ690C/log:\
    :af=/var/spool/lpd/HPDJ690C/acct:\
    :mx#0:\
    :sh:

Following line added to /etc/rc.conf
lpd_enable="YES"

Kindly advise how to make it.   TIA
