UIPrintInteractionController, turn off Double-sided option?

Solution

var duplex: UIPrintInfoDuplex

As per official documentation:-

If a printer is capable of duplex printing, a switch in the printing options allows users to toggle between single-side and double-sided printing. See the description of the UIPrintInfoDuplex constants for more information.

enum UIPrintInfoDuplex : Int {
    case None
    case LongEdge
    case ShortEdge
}

none: No double-sided (duplex) printing; single-sided printing only.

UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.duplex = UIPrintInfoDuplexLongEdge;
printController.printInfo = printInfo//printController is instance of UIPrintInteractionController

Problem

When using UIPrintInteractionController, it is easy to turn off the 'page range' and 'number of copies' options ``` UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController]; pic.delegate = self; pic.printInfo = pif; pic.printFormatter = formatter; pic.showsPageRange = NO; pic.showsNumberOfCopies = NO; ``` Is there a way to TURN OFF the Double-sided option? Conversely, has anyone actually confirmed with Apple, that it is impossible to turn off the double sided option? If so thanks.
