Postscript Font Troubles

dgreco3917

I am using BIRT 2.2 and the provided servlets to print a report directly on the server. The report in question has a barcode implemented as a font. I've managed to get the viewing servlet to output the PDF with the barcode showing up fine. However, the postscript generated by BIRT won't print on any postscript printer I've tried (Xerox Workcentre 5050, HP 9000). The Xerox prints out a Postscript error message (invalidfont), the HP dies completely, displaying a "Service Error" on the LCD. I can see the commands in the generated Postscript to embed the font and use it, but I don't know enough Postscript to say whether it is valid or not. I can view the file properly using Ghostscript/Ghostview on Windows. I also tried the BIRT 2.3 report designer and chose Preview as Postscript and printed that, same results, though the PS file does look different.

What else can I do here? Is there a bug in the Postscript emitter?
