Postscript uses vector rather than the bitmap representation used in PCL
wherever possible - also many Postscript printers can accept jpegs directly.

Vector representation is rather like a Drawfile (eg Corel Draw) and bitmap
like a Sprite or BMP and jpegs are smaller than simple bitmaps. Hence
Postscript print job files are almost always smaller than PCL.

An exception might be with PCL 6 which has vector capability but as far ss
I know is not used by RISCOS.

Interesting, but not significant nonetheless since I have ample space
for spooling. Tell me, how can I see the size of a PCL print file on
Linux? Is there any way to stop the print file from being sent to the
printer and kept for further use?

Not too many people run RISKOS...
