Jim,

It sounds like you're describing the difference between the Amyuni single-user license and the developer license. Both allow for the programmatic creation of a PDF printer driver that can be used from within your application. The single-user license also allows for the creation of a permanent PDF printer driver which can be used from any Windows application. The developer license permits royalty-free distribution but is relatively expensive for the developer and does not provide any functionality to the end-user outside of your application. If you can convince your clients to buy a single-user license for each desktop then you would not need the developer license, so this is cheaper for you but not necessarily for your client (depending on how you price your app). There is also a site license which may be cheaper than x number of single-user licenses beyond a certain number of machines.

>I've been previously confused about the name and capabilities of the Amyuni products, too. For the purposes of clarity, I'll call them the Cheap One and the Not So Cheap One. A reply in a CompuServe forum that I read a while back seems to indicate that the Cheap one does indeed allow you to create PDFs, working as a printer driver the way that the PDFWriter does, but it also offers enough direct program access to allow you to print under program control, thus beating Adobe on both price and capabilities as a low end solution. The difference is that it's just a single-user license. This would leave the option open, though, for your clients to pony up the minor cost of the Cheap One to add PDF capability that your program could take advantage of.
