printing the screen, yet again

[Michael G. Hart]

ok, I got the post from John Yates, a summary of the ways to get
a screen image into other formats.

So, I took a snapshot of the screen.  Ran tops on it, to get the
file snap.ps.

I can't get this file to print.  Our Irises spool their printing
to a Mac running A/UX, which then prints it to a LaserWriterII NTX.
snap.rgb is 157405 bytes, snap.ps is 1878266.  Is this norm?

I looked at the snap.ps file; it looks like PS to me:-(

Has anyone done this exact thing?  I.E. the following 
	1. snap the screen
	2. run it through tops :  tops snap.rgb snap.ps
	3. either :
			lp snap.ps    (knowing that the printer is a network
					       Apple LaserWriter)
	or
			cat snap.ps | lp

	4. gotten a printout?

How about taking the snap.ps over to the mac, and pasting it into
a document??
