Platform-independent printing

I am working on a project that requires printing to work across platforms of a fairly complex form with fields that get filled out. I currently have an iPad version of it, which prints beautifully and works well. I am however worried as this works by designing the form in IB, then filling it with a UIViewController and then printing it. However, the app will have to get a web version in the very near future and it is incredibely important that whatever the device I use to print the form, it must look the same. This seems like an impossible task so I was wondering,

Do you know of a way how I can print a complex form that was originally designed in IB from web (and possible Win or Mac apps) so that it always looks the same on paper?

Thanks
