I hope 2.06 works as well. I never received any license keys, only a serial number, and I'd have to buy the new version outright to get them. That's an added incentive to make it work! The information about installing the printer with the client app and the distinction between PrinterInit and PdfPrinterInit is clear as mud at this point. But, that's where trial and error comes in!

I've looked at dozens of other PDF products and all seem to range between $1000 and $1500 for a version without a user interface even though they provide varying degrees of functionality.

Thanks again for your encouragement.
