On iOS emulator :I can select a printer from the UIPrinterPickerController dialog and retrieve the printer I can connect to that printer with UIPrinter.contactPrinter I can send multiple jobs to that printer silently (no dialog) with UIPrintInteractionController Same code or any similar code on macOS Catalyst :Absolutely nothing is working. I see nothing, no dialog, no errors in the log.

My printer a Samsung, seem to have totally lost the plot. It would not print anymore but only spit out ASCII type mambojambo. But there is no logic to it as the same file could come out wrong and on the next print fine. I would appreciate if apple would be a little bit more sensitive that not only their world exists but also other devices that need to connect and work.

Hello, With the new iPadOS updates in iPadOS15 we are finally able to print in landscape so my company is trying to migrate our POS systems to tablets as it makes our client experience more seamless. We have designed a coded template for a web pages receipt that allows us to print in a specific format that fits our letterhead. We currently the following code in order to format the printer to automatically print in landscape from Chrome with 0 margin. @Page {Margin:0px orientation:landscape} On iPadOS, the page does not automatically orientate to Landscape in the print which is not the biggest issue, but the Margin:0px is not read even with the Safari>Advanced>Experimental Features>@page CSS at-rule support toggled on. We have attempted to restart the iPad in case it needed a reset to take effect but it still does not seem to follow the at-rule. Is this an issue others are having, or is there a workaround to adjust printout margin?

I would like to use my iPad Pro and print documents and files remotely over the internet to my office. Considering the iPad not being on the same network, I have installed and configured a Rasberry pi with Cups and it is working nicely while being on the same network. I would like to know if there is any function that I can mix and match to achieve the goal. Since Google Cloud Printing is out of the game now, it is quite difficult to find an alternative.

Now that CUPS backends, filters and PPDs are deprecated, I'm trying to set up a print to file queue using ippeveprinter. But I can't get it to work. Anyone know anything about it? I've tried: ippeveprinter -D file:///Users/Shared/Print/Out -F application/pdf -c /usr/local/bin/pscommand.sh myprinter and then created a shell command that runs: cupsfilter $1 I've tried it without the -c flag as well. Sometimes I've produced .prn files, and occasionally .urf files (but without changing anything I've also got zero length files). But I just can't get a PDF into my destination folder.

We would like to have some visibility of Iphone printing. Is there a way to store or monitor the Airprint logs?

Hi. We are a printer manufacturer and support AirPrint in our products. Can you provide the schedule for the next AirPrint Certification?

Hello Devs ! We are trying to use cordova plugin in our ionic app : https://github.com/katzer/cordova-plugin-printer To print documents silently via an AirPrint enabled printer. It works on iOS 14 devices / simulators but we notice that there is an error while we try to print from iOS 15 simulators : https://github.com/katzer/cordova-plugin-printer/issues/281#issuecomment-949167538 Can we please know if this is something that can be handled from cordova plugin level or is this something that is changed / blocked at the iOS native level for any background actions ? Any suggestions / comments will be highly appreciated. Thanks ! Amol

I am printing a pdf from iOS app. When printing I want to eliminate printers default border and provide it my own margin. Each printer has its own margin and I have to overcome that with my margin.

I'm working on a medical enterprise application and was wondering if users can confidently print documents containing PHI via AirPrint without any major security risks. Obviously the local network they're operating on should be configured with the highest level of security. I couldn't find any technical details regarding the security of the AirPrint protocol and was hoping someone could provide some additional information on the AirPrint protocol.

Since I updated the OS, my HP PageWide printer is not printing PDFs and Word files - only lines and squares instead of the text. Tried renaming printer, reinstalling printer but no luck. Able to print mail etc.

Hi everbody, I have two issues for one of my client and i wanted to know if someone has the solution or any clue. They have 50+ iPads Pro 11 and they are using the Meraki System Manager to managed their iPads. They use Safari to access to a specific web page and they have to enroll the iPad to their software through this web page. In fact, when the iPad is enrolled through this web page, there is a token that is stored into the safari local storage. This token is used to keep the enrollment up. But if the safari history or settings are deleted by any way, the token is suppressed and they have to re-enrolled their iPad again. It seems that when we modify the Meraki profile and the new one is pushed into the iPads, safari settings/history are cleared and they always have to re-enrolled their iPad through the web page. Is there have any option to prevent this ? I have added a "Web Content Filter settings" but it seems that they can't use the iOS print button in this configuration. They are using a web clip in full screen. If they go to this website directly through Safari (not with the web clip), they can use this button and print. If i remove the "Web Content Filter", they are able to use this button to print through Safari or the web clip. Is it a normal way for the "Web Content Filter" to runs like this or not ? Is there any possibilities to prevent this ? If I have to remove the "Web Content Filter", is there any solutions to filter the websites ? Thanks for your help guys !

Hi, I'm having trouble printing a QRCode to the proper size. I pass it, as a UIImage, to a UIActivityViewController and it prints, but at the full width of the A4 page. I've been looking into all kinds of ways to try and shrink it down, but without success. Is there an image equivalent of UISimpleTextPrintFormatter or something along those lines that makes it simple? Do I need to use a UIViewPrintFormatter? Any help greatly appreciated.
