[comp.lang.postscript] Help with Postscript operator

vss@mathcs.emory.edu (V.S.Sunderam) (09/29/89)

I have a document with the operator (function?) 
BeginDviLaserDoc 
in prolog - and cant find a definition for it.
Has anyone come across this before?

I would appreciate receiving a definition or suggestions for a workaround.

Thanks in advance
