System.print in Perspective

[PGriffith]

Victor's correct, there's no analogue for the system.print functionality that works in Perspective.

You're not alone in wanting it ([FEATURE] Print Perspective view to default printer. (or generate PDF of view functionality), Perspective Print Screen, Perspective Printing and Printer Configuration, and so on) but currently there's no standardized cross-browser way to actually do what anyone wants. Until that capability exists in browsers, our hands are basically tied. We don't want to introduce a feature that works in one browser (e.g. Chrome) but not in Firefox or Safari - that's just asking for a headache for support, training and every application developer's end users.

For now, I'd say to train your users to use the tools available in the browser, e.g:

Perspective Screenshot Capture

This would currently require a custom module - capturing screenshots from web browsers is a surprisingly complicated problem. Your best bet in the short term might be to try to train users to use built-in browser tools - new versions of Firefox, for instance, have a very powerful built in screenshotting tool. What’s the use case of these screenshots, out of curiosity?
