Printer paper size mismatch

[Bar26]

Having a problem with printing which may have been caused by a Windows 11 update as it worked fine till April 26 - I don't print often!  When I tried again I got some sort of Windows message suggesting my Deskjet 3630 did not have the right drivers and only offered OneNote printing.  Reintalled HPSmart and updated all drivers, and uninstalled/reinstalled printer,  and printer was recognised.  However, I still can't print as I now get a 'paper mismatch' error every time.  In Windows Settings>Bluetooth and devices>devices>printers and scaners>(selecting my printer - Deskjet 3630)>Printer Properties, the only available paper size shown is 'letter' and I can find no way of changing this to A4 which is what I use or seeing any wider choice.  When I print from Word, on the document print properties I can select A4, but this still results in a Paper Mismatch error.  Have tried reinstalling, and hard reinstalling printer which were suggested in a reply to a similar problem without any success.  Would be grateful for any help  (not particularly competent with technology so as simple and comprehensive as possible would be appreciated).
