Airprint support - Possible ?

[Neurox]

AirPrint (or/and ePrint) support would be really useful with iPhone/iPad in GLBasic developping.

Gernot ? 

[Moebius]

With a *!*GOOGLE SEARCH*!* code comes up for printing an image.  I can't test it, but the attached file compiles fine.  Because of attachment restrictions, you should rename it to a ".m"...
Not sure if you wanted something more than images, but considering the GLBasic is a graphics program, it's probably more suited to printing images that you render.
Possible GLB code, again not tested because I'd need to upgrade the device and sort out Airprint...

Code: (glbasic) [Select]

IMPORT "C" int __stdcall GLBAirPrint(const char* imagePath)

FUNCTION PrintImage: Image%, Filename$ = "Print.png"

LOCAL Documents$ = PLATFORMINFO$("Documents")
SAVESPRITE Documents$ + "\\" + Filename$, Image
GLBAirPrint(Documents$ + "\\" + Filename$)

ENDFUNCTION

Thanks for source code but...
I realized that the AirPrint doesn't work with ipod touch second generation: (
I'll wait to try the new iPod coming next week.

Hi,
after 3 days full of tests the result is negative 
I've tested the function with iPhone 4 with iOS 4.3.5 and iPod fourth gen
but the printer not receive anything and not print anything

[Moebius]

The original code was an objective C class, and I have no doubt I messed something up when deleting stuff from it 
Unfortunately I can't help here...

Its working from other applications? if not you need a bonjour compatible router

[Neurox]

I'm using a HP B110 printer, AirPrint compatible.

[trucidare]

try it with another application first then with glbasic and tell me the difference

[Neurox]

I've made the test.
First of all I printed a html page from safari and then I printed from my program.
Unfortunately, the printer prints only the html page. 
After printing my app didn't blocked but accept no more commands, as if MOUSESTATE function doesn't return any value.   

[trucidare]

Add a single NSLog(@"Error!"); line if the image is not present and the canPrint else so we could see if the app isnt ready to print

[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.

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  )

[trucidare]

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