Ok. I found this command:
wadesmart at wadesmart:~$ lpinfo -v
network socket
network beh
network bluetooth
direct hpfax
direct hp:/par/HP_LaserJet_4050_Series?device=/dev/parport0
network http
network ipp
network lpd
direct parallel:/dev/lp0
direct canon:/dev/lp0
direct epson:/dev/lp0
direct scsi
serial serial:/dev/ttyS0?baud=115200
network smb

so I tried the command you gave with /dev/parport0 instead of lp0.
Nothing. I tried it after doing sudo -i and received Invalid argument.

So I tried lp0 again after sudo -i and not I dont have anything echoing
to the screen but, I also do not have any printer activity.

Well, I am seeing life!!
Opps, too soon.
Im seeing, "Data Received"  and "Processing Job" but nothing is happening.
Just for kicks I did a Factory Reset of Settings on the printer (since
it was given to me) and as soon as I hit the button for echo "^L"
....etc I see "Processing Job" but still no action.
