Since the “upgrade” to 16, I can no longer print from my iPhone to my two HP printers. Is there anything I can do to fix this, short of leaving Apple and buying an Android phone? Can I revert back to the previous iOS?
iPhone 12 Pro, iOS 16
Rolling-back to an earlier version of iOS/iPadOS is not possible.
All System Updates are digitally signed by Apple - and can only be installed whilst the digital signatures remain valid. After release of a new iOS/iPadOS version, the immediately preceding version continues to be digitally signed by Apple - however, usually within a few days, Apple will revoke the digital certificate with which the earlier version is signed.
For AirPrint, see:
Apple AirPrint is a driverless connection protocol. A high proportion of modern printers intended for Home, SoHo and Business environments now support AirPrint. Check your printer model against this list:
About AirPrint - Apple Support
If your printer supports AirPrint - and is set-up correctly - should you continue to experience difficulties your WiFi Router may be unexpectedly failing to pass Apple Bonjour traffic on you local network - or your WiFi Router or Network Switch may be blocking this (or other) device discovery protocol(s).
This can occur for a number of reasons. Ensure that your wired and wireless network segments are part of the same IP-subnet, are not defined as separate VLANs - or that one or other are defined as “guest” networks, or placed in a DMZ. You may find that your router has a setting that limits/restricts broadcast and network discovery traffic; by example, if your Router has an IGMP Snooping setting, try toggling this or similar settings. Your Router WiFi settings may also have privacy settings that isolate WiFi clients from each other; if present, ensure these settings are disabled.
The Apple Bonjour protocol uses mDNS (Multicast DNS) UDP port 5353.
You may find that restart of your network components will resolve the problem. You’ll need to restart your network devices in the correct order. Assuming that you WiFi Router provides DNS services for your network, restart devices in this order - allowing time for devices to fully boot/restart prior to restarting other devices:
Restarting your iPad/iPhone, after restarting other devices in the correct sequence, is most simply achieved by a forced-restart of the device:
Force restart iPhone - Apple Support
Force restart iPad - Apple Support
If you continue to have difficulties, check to see if your iPad/iPhone is using the new WiFi Private Address feature. This feature is intended to provide additional privacy and security when using “public” (untrusted) WiFi networks.
Settings > WiFi > [Your WiFi Network / SSID] - tap the “i” icon - Private Address
The Private Address feature is largely unnecessary for your home WiFi network; if enabled, Private Addressing can interfere with anticipated operation of other devices, such as AirPrint/Airplay. In such circumstances, you may need to disable this feature - and can be enabled or disabled for each individual network.
Use private Wi-Fi addresses in iOS 14, iPadOS 14, and watchOS 7 - Apple Support

How were you printing to that year-old non-AirPrint printer previously? If it was through some manufacturer-supplied app, perhaps you need an updated version of that app.
You bypassed the question by endless rambling on about how great AirPrint is. For those of us who do not have an AirPrint printer and do not wish to buy one since their existing printer has several more years of life left----what about us? I purchased a new printer just a year ago and a very nice one too; now it's so much garbage... Thanks (for nothing) Apple.
How do I print to a non-airPrint printer?
