added some options and enhancements to the print output:

-ps: added formatting hints for ghostscript, so pdf conversion will be much better
-ps: print a thin line at the top and bottom of each page
-ps/text: add an option to start a new page for every packet (formfeed)

+%
+% Ghostscript http://ghostscript.com/ can convert postscript to pdf files.
+%
+% To convert this postscript file to pdf, type (for US letter format):
+% ps2pdf filename.ps
+%
+% or (for A4 format):
+% ps2pdf -sPAPERSIZE=a4 filename.ps
+%
+% ... and of course replace filename.ps by your current filename.
+%
+% The pdfmark's below will help converting to a pdf file, and have no
+% effect when printing the postscript directly.
+% 
+
+%   This line is necessary if the file should be printable, and not just used
+%   for distilling into PDF:
+%
+/pdfmark where {pop} {userdict /pdfmark /cleartomark load put} ifelse
+%
+%   This tells PDF viewers to display bookmarks when the document is opened:
