ios - Printing photo from URL using UIPrintInteractionController clips parts of my photo -

-

i'm trying photo printed through uiprintinteractioncontroller. should print 4x6, , does, clips parts of photo (not of it, half inch on both directions). i'm printing directly url, , final pixel size of image 600 x 900 px.

does apple have specific pixel size expects images print 4x6 perfectly? know it? doing wrong?

code: 

nsurl *imageurl = [nsurl urlwithstring:urlofimage]; nsdata *data = [nsdata datawithcontentsofurl:imageurl]; uiimage *imagetoprint = [[uiimage alloc] initwithdata:data];  uiprintinteractioncontroller *controller = [uiprintinteractioncontroller sharedprintcontroller];  if(!controller){     nslog(@"couldn't shared uiprintinteractioncontroller!");     return; }      controller.delegate = self;  // need completion handler block printing. uiprintinteractioncompletionhandler completionhandler = ^(uiprintinteractioncontroller *printcontroller, bool completed, nserror *error) {     if(completed && error)         nslog(@"failed! due error in domain %@ error code %u", error.domain, error.code);  };  // obtain printinfo can set our printing defaults. uiprintinfo *printinfo = [uiprintinfo printinfo];  // application prints photos. uikit pick paper size , print // quality appropriate content type. printinfo.outputtype = uiprintinfooutputphoto; // path image may or may not name our print job // that's we've got. printinfo.jobname = [[imageurl path] lastpathcomponent];  if(!controller.printingitem && imagetoprint.size.width > imagetoprint.size.height)     printinfo.orientation = uiprintinfoorientationlandscape;  controller.printinfo = printinfo;  controller.printingitem = nil;  if(imageurl && [uiprintinteractioncontroller canprinturl:imageurl])     controller.printingitem = imageurl;   if(!controller.printingitem)  {      printphotopagerenderer *pagerenderer = [[printphotopagerenderer alloc]init];      // printphotopagerenderer subclass needs image draw. if taking      // path use original image , not fullscreenimage obtained      // alassetrepresentation.      pagerenderer.imagetoprint = imagetoprint;      controller.printpagerenderer = pagerenderer;  }  [controller presentanimated:yes completionhandler:completionhandler];

the printphotorenderer taken directly apple's printphoto code.

any tips or ideas appreciated!
