iPhone Xs IOS 13.3.1 airprint only prints 4x6

thank you for taking the time to reply. I don’t believe the printer is the problem. The printer will print documents just fine from my desktop computer and it does so wirelessly. It’s only when I try to print documents from my iPhone that I’m limited to 4 x 6 size paper.

Thank you for the link. I’ve read this before but I decided to reconnect to my WLAN and reset the printer to my network. This did not solve the issue. Both my wife and I have been able to print to this printer for the years since we bought it. But just recently both our iPhones (both Xs) stopped allowing us to change the paper size to full size 8.5x11. We can only print 4x6.

I thought I would let everyone know that my problem found a solution. And it’s very curious as to how it happened. I went to the local Apple store and talked to one of the staff. They were puzzled by the situation and suggested that I allow Apple technical support to contact me by phone this evening. I just got off the phone with their technical support. While I was on the phone after explaining my problem, waiting for them to find a solution, I decided to pull up a document and try printing so I could explain what exactly I tried, step-by-step. Lo and behold my iPhone allowed me the option of choosing “letter” size this time. Of course the option to choose “letter” was the missing option all along. I asked the technician on the phone if they had done anything that might’ve caused my phone to start working properly. They said ‘no’, they had not done anything. We were both puzzled but enjoyed a good laugh at how peculiar it was that the solution materialized. I had them wait on the phone while I went upstairs and had my wife check her phone as well. Believe it or not, her phone, too, was now working properly and allowed her to also choose “letter” size. We were all baffled. I’m glad my phone is communicating properly with my printer now, but a little annoyed that none of us know what caused the solution. I just wanted to pass that along. If anyone else has a similar problem maybe all they need to do is have Apple technical support called them. (I suspect the mere fact that they connected to my phone was enough to reestablish the proper defaults that may have been corrupted in my air print communicating.) Thanks again for the suggestions.

Apologies for not including the printer info. The printer is a Canon PIXMA MG7520. It’s currently set up to print 4 x 6 in tray number one and letter size in tray number two. There are no options to change the tray order.

Thanks for Taking time to reply. I’ll continue my research. Take care.
