[comp.lang.postscript] the file operator

russell@cerberus.bhpese.oz.au (Russell Sparkes) (04/10/91)

Basically, how does the file operator work, does it only work on devices
internal to the printer, or can it go back along the io channel to
the OS that sent the code to the printer? 

All help is hugely appreciated

Please reply by email.
