-Environment iPad：10th、iOS：17.6.1、Printer：EPSON PX-S730 -Question Is this phenomenon due to iOS specifications? Restarting the iPad solves the problem, but I don't think it's best practice to restart it every time you reproduce it. Please let me know if you have a good solution. -Problem I am developing a print preview screen using AirPrint's print method. If you submit a print job using AirPrint on an iPad while the printer is turned off and then cancel it, the print center remains on the app switcher. After that, when I turned on the printer, I was no longer able to print using AirPrint on my iPad. When using AirPrint's API "print" and when printing by launching AirPrint from Safari, we have confirmed the same behavior in both cases. -How to reproduce Turn off the printer Print from iPad to printer using AirPrint Launch the print center from the app switcher, cancel the print job, and set the number of print jobs to 0. When you start the app switcher, the Print Center app remains. In step 4, turn on the printer and print from the iPad to the printer using AirPrint. When you start Print Center from the app switcher, the print job status becomes "Waiting" and the print job is not executed. -Expected result When there are no print jobs on the print center, the print center is closed on the app switcher. You can print from your iPad to the printer using AirPrint, and then print from the printer. -Actual results When there are no print jobs on the print center, the print center remains on the app switcher without being closed. In the above situation, when printing from the iPad to the printer using AirPrint, the printer does not print. When I start the print center, the print job status is "Waiting" and is queued. -Code printInfo.jobName = "Print Job" printController.printInfo = printInfo let pdfURL = Bundle.main.url(forResource: "sample", withExtension: "pdf")! printController.printingItem = pdfURL let printer = UIPrinter(url: printerUrl) printController.print(to: printer, completionHandler: { [self] printController, completed, error in if(error != nil){ print("error"). }else if completed{ print("completed") //this scenario handles completion response }else{ print("cancel") } }) -Link of API used Apple Developer-AirPrint-print -Similar inquiries Apple Developer Forum - Print Center on my iPhone shows a pending document to print and I can't get rid of it

Environment iPad：10th iOS：18.1 Printer：EPSON PX-S730 Problem In iOS18.1, When printing with AirPrint, PrintCenter is no longer displayed on AppSwitcher. In iOS17, PrintCenter was displayed on AppSwitcher. Question Is this a specification change? I would like to know if there is a way to check PrintCenter on AppSwitcher in the same way as iOS17. Ref No information after iOS18.1 update. https://support.apple.com/ja-jp/109349 There is no mention of AirPrint updates in the AppleDeveloper release notes. https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18-release-notes https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18_1-release-notes
