Question

The program I’m writing runs under OS X 10.5 Leopard. My target has its Base SDK and Deployment Target both set to Mac OS X 10.5. When I initiate printing, my print dialog doesn’t show the Page Attributes option in which the user can select page size and orientation.

Other programs running under Leopard do show this option:

Here’s the code that initiates printing:

-(void)print {
    NSPrintInfo *printInfo = [NSPrintInfo sharedPrintInfo];
    TemperaturePressurePrintView *printView = [[TemperaturePressurePrintView alloc] initWithFrequencies:frequencies];
    if (printView) {
        [[NSPrintOperation printOperationWithView:printView printInfo:printInfo] runOperation];
        [printView release];
    }
}

What do I need to do to get Page Attributes to show up in my print dialog?

This was a tough thing to search for because the results were mostly about using the print panel, not programming one. I finally found a clue on Cocoabuilder where it mentions NSPrintPanelOptions and NSPrintPanel‘s -setOptions: method.

This code accomplishes what I need:

-(void)print {
    NSPrintInfo *printInfo = [NSPrintInfo sharedPrintInfo];
    TemperaturePressurePrintView *printView = [[TemperaturePressurePrintView alloc] initWithFrequencies:frequencies];
    if (printView) {
        NSPrintOperation *op = [NSPrintOperation printOperationWithView:printView printInfo:printInfo];
        [[op printPanel] setOptions:[[op printPanel] options] | NSPrintPanelShowsPageSetupAccessory];
        [op runOperation];
        [printView release];
    }
}
