PPDs and PostScript
CallPPD (procedure)
Calls a section of the PostScript Printer Description (PPD) file and executes it on the printer. Use this to set printer options such
as the input tray or duplexing options. The tokens and subtokens you use as arguments with this function must be defined in

file for the token-subtoken combination and then prompts the printer to execute the corresponding code.
Syntax
callppd( token, subtoken )
Arguments
token
This is the string to search for in the PPD file (for example, Duplex).

endif()
