Postscript Printer Question

[Bruce Pourciau]

This is a LaTeX rather than LyX question. Concerning the quality of  
the output -- specifically for printing LaTeX and eps files, but also  
more generally -- what would be the difference between printer A and  
printer B, if A is described as having "standard postscript support,"  
while B, under "printer fonts," says "26 scalable fonts" but there's  
nothing about postscript support. We will be getting a new printer  
for the department of mathematics, and we'll need good reasons if we  
ask for the more expensive printer A.

Any help would be appreciated.
