Ref- https://support.apple.com/en-in/guide/deployment/dep3b4cf515/web When we deploy an Payload with identifier "com.apple.airprint" , It will add the deployed printer configurations to printers list in mac. Which additionally needs the mac user to add it from Settings -> Printers -> Add Printer -> (Deployed Printer Configuration will be listed here) Select the printer -> Click Add . Screenshot where user need to add it manually after profile association is attached below. Now the Printer is available to be used ,when an share option in any document is clicked. Why this flow requires multiple to and fro. Can it be able to deploy the printer straight to Printers available List instead of manually adding from the above screenshot

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

-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

We are hoping to port our app which requires printing to visionOS. Can I check if visionOS supports AirPrint/printing? If anyone has already done it, anything we should watch out for?

Hi, In Windows and Linux, it's possible to ask a printer to print content programmatically in Black & White. This may be referred to as "Monochrome", "Grayscale", "B&W", depending on the device driver. For feature parity with other operating systems, I'd like to do the same -- programmatically -- in macOS using Objective-C or Swift. Is this possible? If not, what's the best, formal way to request this useful OS feature to Apple so that it may be added in a future release? More context about this request: https://github.com/openjdk/jdk/pull/18195

After updating to the lates OS many of the standard page sizes have disappeared from the HP Officejet Pro 7740 setting such as the full bleed 8.5 x 11 and full bleed 11 x 17... is this up to  to correct or HP?

For printing from worker thread to a UIPrinter(whose url i have saved ) i am doing this and able to print : func PrintPdfDocument (pDocument:Data) { // Create a print interaction controller let printController = UIPrintInteractionController.shared // Set the printing options let printInfo = UIPrintInfo(dictionary:nil) printInfo.jobName = "Print Job " printController.printInfo = printInfo printController.showsPageRange = true // Set the PDF document to be printed printController.printingItems = pDocument printController.print(to: defaulttprinter, completionHandler: { (controller, completed, error) in if completed { print("Printing successful!") } else { if let error = error { print("Printing failed with error: \(error.localizedDescription)") } else { print("Printing was canceled.") } } }) } When i call PrintPdfDocument (pDocument:Data) function , more than once with diffrent data shown below : DispatchQueue.global().async { PrintPdfDocument (pDocument:data1) } DispatchQueue.global().async { PrintPdfDocument (pDocument:data2) } DispatchQueue.global().async { PrintPdfDocument (pDocument:data3) } Printer is printing only one document(data1) . For other call is not executing printController.print (to....) function inside PrintPdfDocument.

I'm working with cupsfilter command to convert files from PDF to PS. We had been previously working with cupsfilter on Linux, but we had to migrate to macOS and some of the command line arguments are not compatible. In particular, we can't control autorotation and scaling on macOS. They seem to be "on" by default, but there are some cases where we need to turn them "off" so page doesn't rotate or scale to fit automatically. On Linux, those options are controlled with -o nopdfAutorotate and -o nofit-to-page. Any ideas how to control rotation and scaling on macOS? Thank you very much in advance.

I want to use CUPS in iOS for printing and it is mentioned at many places that we can use cups for printing in ios .But when i import library cups/cups.h ,xcode is giving error "cups/cups.h not found". code i am using in a objective c file : import &amp;lt;cups/cups.h&amp;gt; cups_dest_t *dest; int num_options; cups_option_t *options; int job_id; /* Print a single file */ job_id = cupsPrintFile(dest-&amp;gt;name, "/usr/share/cups/data/testprint.ps", "Test Print", num_options, options); Do i need to intall some driver or any library to make it work ? or is it the case that CUPS is not available for iOS?

After updating to Mac OS Sonoma, we have encountered compatibility issues with our iPad-designed application, specifically with the AirPrint functionality, when it is run on MacOS. The AirPrint feature stopped working properly through UIPrintInteractionController.shared. We have noticed that when we compile the application using Catalyst, the AirPrint functionality is restored and works as expected. However, this solution is not viable for us due to the restrictions associated with the frameworks we are utilizing. We are seeking alternative solutions, and any help or guidance would be highly appreciated to resolve this issue and ensure a seamless and uninterrupted user experience in our application. STEPS TO REPRODUCE Create an app for ipad with just a button and this code var str = "TEST" let printInfo = UIPrintInfo(dictionary:nil) printInfo.outputType = .general printInfo.jobName = "Report" printInfo.orientation = .portrait let printController = UIPrintInteractionController.shared printController.printInfo = printInfo printController.showsNumberOfCopies = false printController.showsPageRange = false printController.showsNumberOfCopies = false let formatter = UIMarkupTextPrintFormatter(markupText: str) formatter.contentInsets = UIEdgeInsets(top: 72, left: 72, bottom: 72, right: 72) printController.printFormatter = formatter printController.present(animated: true, completionHandler: nil) 2.Run it on a MacOS with Sonoma, there is no error on console or anything but it don't work. -If you run it with Catalyst it just works when adding the Printing permission of App Sandbox in Signing & Capabilities.

Starting iOS 16 seeing some crashes related to pdf printing in the crash reporter. It looks like the issue is not so frequent. Also, I'm unable to reproduce the crash.
