Would it be possible to allow the:
Mail.app
Calendar.app
MobileText.app

To be able to print?

I assume that it would be an issue of printer drivers:

http://www.apple.com/downloads/macos...erdrivers.html
http://www.apple.com/downloads/macos...erdrivers.html

If anyone has any ideas on how this might be possible. Maybe even an additional program to do so.. I would Ideally like to be able to include it in these programs..

As this is a great PDA I think everyone would benefit from being able to print right off the phone.

Again any help here would be great.

Well in terms of mail.app and calendar.app, unless you could decompile, add the print button that sends the job to a print spooler, and then prints (I guess via network), then recompile the software, then the only way I could imagine this being possible would be to utilize the databases that they use, by having a 3rd party app read the database, allow you to select the stuff you want to print then send it to the printer via a print spooler. And I think MobileText is open-source, so you could add a print button to send it to a print spooler and then print via network. To get the spooler to work, you would need to use specific drivers for the printer you are trying to print to, which could complicate things a bit, because unless you do custom driver installs, you would need to include a lot of drivers.
