To print from your iPhone to an HP printer, ensure both devices are connected to the same Wi-Fi network. Open the document or photo you want to print, tap the share icon (square with an arrow), and select “Print.” Choose your HP printer from the list. Adjust any print settings, then tap “Print” in the top right corner. Ensure your printer is turned on and has paper and ink. https://123hp-setup-com.us/blog/how-do-i-install-hp-print-service-plugin-for-iphone/
