This is way cool! A few years ago I thought it would be nice to be able to convert documents on the Create Adobe PDF Online (http://createpdf.adobe.com/) web service from your desktop directly. The Internet Printing Protocol (IPP) has been around for a few years and I was just told that the fine folks on createpdf.adobe.com have released it to the world.
Using IPP, you can create a printer instance on your Windows system that points to the online service. No need to have conversion software on your desktop and no need to upload the file to the web service through a browser.
I just went through the installation steps detailed on the createpdf web site and below you’ll see a screenshot of what I saw when I printed a sample page.
The top half shows the printers on my system and the bottom half shows the list of jobs for the “Create Adobe PDF Online” printer. About 30 secs later I received an email with a PDF attachment for the print job.
Great work guys!
[Edited 2005-08-20 per comments below - looks like MacOS can't do IPP over an SSL connection, that's why it does not work on the Mac at the moment - thanks Amit!]
