Problem Description

Every time I print an 11x17 sheet to my new "Pro C720-C720S Fiery" printer through the Bentley Postscript Printer Driver I get an 8.5x11 sheet of paper.

Reason

This particular device does not understand the "Page Size Tabloid1" entry in the delivered .pro file

Steps to Resolve

Create a copy of the delivered "hpttabl1.plt" and name it "fiery11x17.pro".  Edit the new file "fiery11x17.pro" and look at the line that reads:
%%BeginFeature: *PageSize Tabloid1
change it to read:
%%BeginFeature: *PageSize Tabloid
notice that all we have done is remove the number 1 at the end of the line.
We now modify the pscript.pltcfg.
Select the Base Properties tab, expand the "Advanced" property. Locate the entry "Prolog File Name".  Here enter the name of .pro file created above "fiery11x17.pro" (double quotes not needed).  Path to the file, need not be included if in same directory as the Printer Driver Configuration file.
Reload Printer Driver Configuration file.  Prints should automatically come out on the 11x17 sheet of paper.
