The 'duplex' area does not work in any way.
I just want to print double-sided..
The printer sees the last printed setting every time. I want to rewrite this information. please help me.
let printInfo = UIPrintInfo(dictionary: nil)
printInfo.duplex = .shortEdge
let printController = UIPrintInteractionController.shared
printController.printInfo = printInfo
printController.showsNumberCopies = true
printController.printingItem = guide_url
printController.present(animated: ture, completionHandler: nil)
