not a simple fix

there are so many variables involved with printing that it would be next to impossible to create an 'open' interface for other printing companies to use, simply because they would all have to operate in the same way/use same stock/offer services they may not currently offer

although a stupid bit of itegration to put it into acrobat, i think the service it offers is sound, although a simple dedicated client app would be more suited IMHO, just drag and drop the file to the app and fill out the forms, which reinforces the idea of sending to print, e.g. being printed off site rather than being churned out by the toner eating behemoth sat in the office corner
