Add ViewerPrefs PrintScaling=none to pdf created by pcl6?

Hello,

I use a slightly modified pcl6.exe to create PDF output from WordPerfect 
for DOS, and I wonder if it's possible to "bake in" the setting that 
tells the viewer to print without scaling, specifically:

[ {Catalog} << /ViewerPreferences << /PrintScaling /None >> >> /PUT
pdfmark

I see from the source code of pcl6 that you don't support the 
ViewerPreferences, but I wonder if anyone can suggest a way to modify 
the code so that that setting could be added to the output.

I know I'm asking a lot, and will be grateful for any help.
