Hello Everyone,

My printer, it is a Laser engraver, which can accept PCL raster command and HPGL vector command.

1.Because that, I had implemented a raster driver which serves bitmap image file only. But for other hybrid files, like .cdr or .ai, which include bitmap and vector data, I also want to implement a driver to filtering PostScript file to parsing raster and vector data. Is it possible?

2.I had successfully let the bitmap image file to output to my printer. And the filter path I added in PPD file is:
*cupsFilter: "application/vnd.cups-raster 0 rastertoMyprinter"

If I want to add the parsing PostScript driver to PPD file and let it and rastertoMyprinter driver exist at the same. Is below filter path correct?
*cupsFilter: "application/vnd.cups-postscript 0 posttoMyprinter"

3.Any sample is good for me to achieve parsing PostScript file and get raster and vector data?
(At least, I can separate this two kind of data from PostScript.)

Regards,
-
