Airprint support - Possible ?

Feature request > Network

<< < (3/4) > >>

Neurox:
I put in all the points the NSLog(), I discovered that the print is sent to the printer without problems (even if it doesn't print anything) and exit the function but it seems that GLBasic isn't able to control of the screen.

Moebius:
I deleted anything pertaining to 'self' in the class, including the delegate, and if I understand correctly the action should never be recognised as 'complete'. The code is screwed up - find a better example on the internet.

trucidare:
the print controller is a shared thing and could be used outside from classes. but apple uses delegates in all shared things so i need the full code to make it workable

Moebius:
Apple page: http://developer.apple.com/library/ios/#documentation/2DDrawing/Conceptual/DrawingPrintingiOS/Printing/Printing.html
print image code taken from: http://www.iphonedevsdk.com/forum/iphone-sdk-development/67176-airprint-tutorial-simple-print-file-30-lines-code.html
Good Luck! (I don't even understand delegates :giveup:)

trucidare:
very untested and not checked for syntax - please try someone - put them into .mm file
