>Release:        FreeBSD 2.1.0-Development i386
>Environment:

	Observed with HP Deskjet 540 printer.  Using printer on LPT1
(/dev/lpt0).

>Description:

	When I dump anything (tried both cat and lpr) to the printer device 
the following things occur:
#1) Printer immediately loads up the paper as it normally would to begin
printing.
#2) Pauses without printing a single character for roughly 3-5 minutes.
#3) Prints a line or two.  Pauses for a long amount of time.  An average
pause seems to be around 10-15 minutes.  I have a feeling it pauses longer
with longer files.  Then prints another line or two.  Continues looping in
this fashion.

	I'm sure this isn't a problem with my printer.  This exact printer
has worked previously under NetBSD, Linux, and DOS.  Seems to me this might
be some kind of buffer problem in the kernel code.  I've tried printing both
raw text and PCL formatted files and both had the same problem described
above.

>How-To-Repeat:

	Using a HP Deskjet 540 printer (or possibly others too):	
cat <favorite file here> > /dev/lpt0
