Need some assistance...
I have just purchased an HP Laserjet IIIP for use with my IBM compatible
(supposedly) PC/AT.  The problem is, try as I may, I cannot get a "screen
print" (by pressing shift-printscreen).  
	Actually, I do get a text screen print, but following the print pages
and pages of "escape" sequences are printed, with no apparent end (I turn
the printer off to stop it).  When I try to print screen with graphics on the
screen I get a page of excape characters, followed by another set of pages
and pages of escape characters.  I have remembered the GRAPHICS command,
prior to attempting to print screen.
	Some background info'.  My PC is actually an ITT XTRA Professional
Series (AT compatible), 10 MHz 286 (I think), with 1.4MB memory and a 40 MB
hard disk.  Prior to purchasing the HP laser jet IIIp I had an IBM proprinter
which did printscreens perfectly well.
	If anyone out there has any ideas, please reply directly to me, as I
am only an occasional NETNEWS reader.  Thanks.
