Hi Malcolm,

FreeBSD 5.2
Printer HP Desktop 690c
===================

Thanks for your response.

I missed steps 2) and 3) mentioned above.  I performed further test as 
follows;

step-2
# lptcontrol -i -d /dev/lpt0
 
step-3
# lptcontrol -p -d /dev/lpt0
 
both without printout
 
rebooted PC because having got printer turned on. The later could not be 
detected with 'dmesg'
 
** how can I detect the printer to avoid 'reboot' ??????
 
After reboot
# dmesg
Probing for PnP devices on ppbus0:
ppbus0: <HEWLETT-PACKARD DESKJET 690C> MLC,PCL,PML
plip0: <PLIP network interface> on ppbus0
lpt0: <Printer> on ppbus0
lpt0: Interrupt-driven port
ppi0: <Parallel I/O> on ppbus0
 
# ls -l /dev/lpt0
crw------- 1 root wheel 16, 0 Mar 9 01:17 /dev/lpt0
 
Repeated step-2 and step-3 above
(also no printout)
 
# lptest > /dev/lpt0
 
One line printed on 1st paper as follow;
!"#$%&'()*
+,-./0123456789:;<=>?@ABCDEFGHIJK.....XYZ......abcdefghijk.......xyz....
 
It seemed OK but feed-in paper continued with 'no_paper' light on (I put only 
1 paper in the tray)
