Description Yasila 2020-08-16 15:25:22 UTC 
Converted color pdf to pcl using cljet5c and the converted pcl file size gone 10x larger then the actual size.  kindly let me know if need to add any more parameters to reduce the file size. 

moreover it took about 6 mins to convert 300 pages.

Acual pdf size : 13 MB
Converted Pcl size: 108 MB


script used :
-------------

gswin32c.exe -dCompressMode=3 -sDEVICE=cljet5c   -dBATCH -dPDFFitPage -dDEVICEWIDTHPOINTS=612 -dDEVICEHEIGHTPOINTS=792 -dNOPAUSE  -r300 -sPAPERSIZE=a4 -dPARANOIDSAFER  -sOutputFile="" ""

I don't see anything particularly wrong with Ghostscript performance.
108 M / 300 = 370 K per page

The number of pixels on a Letter-size page at 300 dpi is
8.5*11*300*300 = 8.4 M

The fact that the raster form is larger than the vector format is expected.

The used time, 6 * 60 / 300 = 1.2 seconds per page is also quite reasonable.

Little more can be done without a sample file.

This bug is closed because no sample file was submitted.
Yasila, you can still submit a sample file and reopen this bug report.
