"Alphatronics Virtual Port Monitor" is an excellent add-on that can replace print to file functionality. It is independent from the nature of the printout, so both Postscript and PCL out put is supported.

Regarding NT service. With Alphatronics you do not need to create NT service (although I see scenarios where service can be used) and can utilize Alphatronics ability to launch executables for post-processing of the output. We use it for compression and encryption of captured documents before archiving together with information about document owner, client computer name and other environment variables specific to the user that originated the printout. You can also redirect captured document to a physical printer opening interesting possibilities such as "proximity" printing.

Another interesting aspect of using Alphatronics Port Monitor is ability to create high throughput virtual printers that can utilize drivers that are safe for Terminal Services and offloading all printing from TS/Citrix box to external print server running Alphatronics - we achieved throughput of about 2,000 pages per minute processing PCL output through standard HP drivers.

No, it's much simpler than that. I have a printer setup on the machine,
using the MS Publisher Imagesetter driver. This outputs nice clean
Postscript. The printer is set to print to a named file instead of a
standard port. When the named file turns up, my software grabs it and does
its' stuff.

That way, anything that is printable within Windows can be captured.

Anyway, I've found a nice application called Alphatronics Virtual Port
Monitor that comes close enough to doing what I want. I'm just working on an
NT service to fill in the functionality gaps now.

I do this from a similar application to what you've wrote, to create
printable files (office documents).

Presumably at the moment do you use COM to automate an adobe application
to create the PS file?
