Cannot look at contents of file in Print Queue with Sonoma Before Sonoma, after I selected print in a application, e.g., Word, I could double click on the document stored in the Print Queue and the pages would be displayed. With Sonoma, cannot see file contents?? One last thing pertaining to this Print Queue = I can't delete any of the accumulated "Completed" Jobs .. menu item to delete selected Jobs is dimmed??

I want to use the AirPrint API, which is a standard OS printing function, programmatically on an iOS application to print directly to a printer by specifying single-sided printing instead of double-sided printing for the first print after the OS is initialised. 〇Verification environment ・Device: iPad 9 generation ・OS：OS16.6 ・Printer model: EPSON PX-S730 / Brother MFC-J7300CDW / Canon G5030 / EPSON PX-M791FT ※All printers used for verification support AirPrint and are capable of duplex printing. 〇Issue The duplex printing option can be specified from the program using the AirPrint API property "duplex", However, when printing is executed from the program, the specified print option "duplex printing" is not reflected in the AirPrint API. 〇Verification results Installed the developed print verification app on the device in factory default state, and executed the print process from the app to the printer. (1st time) Set the property "duplex printing" = duplex or single-sided in the AirPrint API of iOS → In both cases, printing was performed on both sides. (2nd and subsequent times) Set the property "duplex printing" = duplex or single-sided in the AirPrint API of iOS → In both cases, printing is done on one side. 〇Source Code The print verification application we developed uses the UIPrintInteractionController class in Swift to specify the printing options for duplex printing. We believe we can specify this by setting "info.duplex = UIPrintInfo.Duplex.none" in the following source code and adding it to printInfo. func buttonClick(_ sender: Any) { let printController = UIPrintInteractionController.shared let printInfo = UIPrintInfo(dictionary: nil) printInfo.jobName = "PrintJob from PrintTestApp" // color printInfo.outputType = UIPrintInfo.OutputType.general // duplex mode for the print printInfo.duplex = UIPrintInfo.Duplex.none // set the single side option printController.printInfo = printInfo // PDF printing in project folder printController.printingItem = Bundle.main.url(forResource: "sample", withExtension: "pdf")! // printer settings let printer = UIPrinter(url: URL(string: "ipps://XXXXXXX/ipp/print")!) // direct printing printController.print(to: printer, completionHandler: { controller, completed, error in guard error == nil else { return } }) }

I'm using UIPrintInteractionController(AirPrint) to print documents in my swift application. I was able to print the documents using my application, but all of them are printing in one-sided. Now i want to add a double-sided printing as an option to my application. After some research i found that it can be implement by adding info.duplex = UIPrintInfo.Duplex.longEdge to printInfo. I tried it using the below code. private var printController = UIPrintInteractionController.shared let info = UIPrintInfo.printInfo() info.duplex = UIPrintInfo.Duplex.longEdge <<<<<< info.jobName = "XXXPrint" info.orientation = .portrait printController.printInfo = info printController.print(to: printer, completionHandler: { [self] controller, completed, error in if(error != nil){ print("successfully") }else{ print("Printing error: \(error.localizedDescription)") } } But whether i set it in the code and run my application it is printing the pages by one-sided. So if some one can guide me to double-sided printing workable solution highly appreciated!!
