trouble printing

[Brian John]

Hello, I am having trouble printing from my HP Deskjet 710C printer.  It 
is hooked up via parallel port and I can print fine with it from 
Windows.  However, I can't get it to work in FreeBSD.  I followed the 
instructions here:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/printing-intro-setup.html

Everything seems to be fine.  But when I try to test the printer using a 
command similar to this:

# cat file > /dev/lptN

or this:

lptest > /dev/lpt0

nothing happens.  Does anyone have a clue what I might have done wrong?

Thanks for the help
