` here code

-(void)printphotowithimage:(uiimage *)image {      nsdata *mydata = uiimagejpegrepresentation(image, 1.f);     uiprintinteractioncontroller *pic = [uiprintinteractioncontroller sharedprintcontroller];      if (pic && [uiprintinteractioncontroller canprintdata:mydata]) {          pic.delegate = self;         uiprintinfo *pinfo = [uiprintinfo printinfo];         pinfo.outputtype = uiprintinfooutputphoto;         pinfo.jobname = @"my photo";         pinfo.duplex = uiprintinfoduplexlongedge;          pic.printinfo = pinfo;         pic.showspagerange = yes;         pic.printingitem = mydata;          pic.printformatter = format;         [format release];          void(^completionhandler)(uiprintinteractioncontroller *, bool, nserror *) = ^(uiprintinteractioncontroller *print, bool completed, nserror *error) {              [self resignfirstresponder];              if (!completed && error) {                 nslog(@"--- print error! ---");             }         };          [pic presentfromrect:cgrectmake((self.view.bounds.size.width - 64) + 27, (self.view.bounds.size.height - 16) + 55, 0, 0) inview:self.view animated:yes completionhandler:completionhandler];     } }  - (uiprintpaper *)printinteractioncontroller:(uiprintinteractioncontroller *)printinteractioncontroller choosepaper:(nsarray *)paperlist {     cgsize pagesize = cgsizemake(6 * 72, 4 * 72);     return [uiprintpaper bestpaperforpagesize:pagesize withpapersfromarray:paperlist]; } 

just code. should use uiprintpagerenderer property give draw area?

`

first should set

 /*  printphotopagerenderer *pagerenderer = [[printphotopagerenderer alloc]init];     pagerenderer.imagetoprint =image;     pic.printpagerenderer = pagerenderer; */  - (void)printimage { // obtain shared uiprintinteractioncontroller uiprintinteractioncontroller *controller = [uiprintinteractioncontroller     sharedprintcontroller]; controller.delegate = self; if(!controller){     nslog(@"couldn't shared uiprintinteractioncontroller!");     return; }  // 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]; uiimage *image = ((uiimageview *)self.view).image; [controller setdelegate:self];   printinfo.outputtype = uiprintinfooutputphoto;  if(!controller.printingitem && image.size.width > image.size.height)     printinfo.orientation = uiprintinfoorientationlandscape;  // use printinfo print job. controller.printinfo = printinfo;  //  since code below relies on printingitem being 0 if hasn't //  been set, code sets nil. controller.printingitem = nil;   #if direct_submission // use url of image asset. if(self.imageurl && [uiprintinteractioncontroller canprinturl:self.imageurl])     controller.printingitem = self.imageurl; #endif  // if aren't doing direct submission of image or reason don't // have alasset or url our image, we'll draw instead. if(!controller.printingitem){     // create instance of our printphotopagerenderer class use     // printpagerenderer print job.     printphotopagerenderer *pagerenderer = [[printphotopagerenderer alloc]init];     // printphotopagerenderer subclass needs image draw. if taking     // path use original image , not fullscreenimage obtained     // alassetrepresentation.     //pagerenderer.imagetoprint = ((uiimageview *)self.view).image;     pagerenderer.imagetoprint =image;     controller.printpagerenderer = pagerenderer; }  // method use presenting printing ui depends on type of // ui idiom executing. once invoke 1 of these methods // present printing ui, our application's direct involvement in printing // complete. our delegate methods (if any) , page renderer methods (if any) // invoked uikit. if (ui_user_interface_idiom() == uiuserinterfaceidiompad) {     //[controller presentfrombarbuttonitem:self.printbutton animated:yes     completionhandler:completionhandler];  // ipad      [controller presentfromrect:cgrectmake(0, 0, 50, 50) inview:_btnprint animated:yes     completionhandler:completionhandler]; }else     [controller presentanimated:yes completionhandler:completionhandler];  // iphone  } 

and should set printphotopagerenderer
