Not sure what documentation you are reading, but my documentn
doesn't say anything about sending output to a file at all.
It says that output is sent to the printer in vector (as opposed
to bitmap) form. Of course, you might be able to re-direct the
output to a PostScript file if your Dialog_PrinterSetup will
allow it. (My Lexmark printer setup allows all kinds of things,
including redirection to a Postscript file, but encapsulated
PostScript is not among them.)
And, in addition, my documentation says to use the VECTOR
keyword as a keyword to the DRAW method:
Printer = OBJ_NEW ('IDLgrPrinter')
ok = Dialog_PrinterSetup(Printer)
IF OK THEN Printer -> Draw, Scene, vector=1
When I do this I find I get significantly faster rendering
to the printer. :-)
