Pull Printing being that you print to a nebulous print queue in the sky and then authenticate to any printer and it Pulls your print job to it. Similar to this STR at all?

There have been some moves to cloud-based solutions, but there are serious legal issues involved with that approach...

Basically a printer/service can tell the client that it is a paid printing service (printer-charge-info-uri, printer-charge-info) using the existing IPP definitions introduced in the recent IPP JPS3 spec. We've added some additional attributes, job-state-reasons keywords, and status codes to that spec (these will show up in the CUPS IPP documentation soon, and I plan on proposing them as extensions for paid printing to the PWG) to allow the client to know when the user needs to visit the printer-charge-info-uri web page to "buy" more printing, and the platform UI can use the information provided to do the appropriate user notifications...
