I'm using a UIMarkupTextPrintFormatter to print some HTML from my app. It works great if I let the print formatter print to the entire page.
But I want to limit the formatter to printing on one half of the page - and to accomplish this I set the contentInsets property once I know the paper size (I set contentInsets when the UIPrintInteractinControllerDelegate method - (UIPrintPaper *)printInteractionController: (UIPrintInteractionController *)pic choosePaper:(NSArray *)paperList is called.)
This works too - the print is correctly limited to the area of the page defined with the contentInsets.
But the number of printed pages is wrong. The number of pages I get is as if the print job had been using the default contentInsets (0,0,0,0).
How can I get it to print the correct number of pages? And why does the pageCount property on the UIMarkupTextPrintFormatter always return 0?
Here's the print job setup code:
UIPrintInteractionController* pic = [UIPrintInteractionController sharedPrintController];
pic.delegate = self;
UIPrintInfo* pi = [UIPrintInfo printInfo];
pi.orientation = UIPrintInfoOrientationLandscape;
pi.outputType = UIPrintInfoOutputGrayscale;
pi.duplex = UIPrintInfoDuplexNone;
pic.printInfo = pi;
UIMarkupTextPrintFormatter* mtpf = [[UIMarkupTextPrintFormatter alloc] initWithMarkupText: myHTML ];
pic.printFormatter = mtpf;
[pic presentAnimated: YES completionHandler:^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error)
{
}];
and, the delegate method:
- (UIPrintPaper *)printInteractionController: (UIPrintInteractionController *)pic choosePaper:(NSArray *)paperList
{
// we want letter paper
UIPrintPaper* printPaper = [UIPrintPaper bestPaperForPageSize: CGSizeMake( 612 , 792) withPapersFromArray: paperList];
UIMarkupTextPrintFormatter* mtpf = (UIMarkupTextPrintFormatter*)pic.printFormatter;
CGFloat padding = ( printPaper.paperSize.height - printPaper.printableRect.size.height ) / 2.0;
mtpf.contentInsets = UIEdgeInsetsMake( 0, 0, 0, (printPaper.printableRect.size.height / 2.0) + padding );
// always 0 ???
NSLog( @"pageCount: %d", mtpf.pageCount );
return printPaper;
}
