[WinPrnDev] Re: Creating a Printer Driver

Jeff
After rereading your email its clear to me that either I have to learn how to 
write me own RedMon port to work with my own GhostScript program to produce a 
PDF of any jobs printed to it (convert to PDF on Client Side)
OR 
Print to postscript and write my own Port monitor to upload the PostScript (The 
spool file i believe ) File up to the server and do the conversion there. And 
if you say that redmon and ghostscript dont work on newer versions of microsoft 
windows I have to admit this seems like the more beneficial route of action.
Or I can work with a third party software that already prints to PDF and I have 
to work with writing my own port monitor, having the PDF already ready just 
seems like the tidier and more efficient option because it lessens the overhead 
on the server.

I would love to hear your thoughts on this everyone.
RegardsSam
