No double-sided print option on iPad for certain docs
I have iPad (18.5), Chrome (134.0.6998.33), and a new wireless HP ENVY Inspire 7255e printer. I am always able to double-side print 2 or more consecutive Chrome webpages via my iPad. But it doesn't give me the double-sided print option for certain other files, or from certain other apps. Two examples are: (1) when I try to double-side print two or more photos selected in Apple Photos, Gallery, and Camera; and, (2) when I try to double-side print two or more files embedded in (not attached to) a Gmail message. Doesn't seem to matter if I use AirPrint or "Print with HP Smart". BTW, it seems to me I might have been able to double-side print most of the time prior to my new HP printer's installation a month ago?! AI Overview in Google Search is great, but it is giving me contradictory solutions this time - depending how I ask the question! Please advise if there is a global working solution that would always provide a double-sided print option regardless of the type or source of file(s) I need to print? Thanks in advance.
