Laserjet M1217nfw

My old LaserJet M1217nfw has given years of valuable service as a printer and scanner. I've just bought a new HP laptop and the printer is no longer working correctly. It prints more slowly than it used to... and, more importantly, it prints the entire page of type in a very small character size - such that the entire page is just occupying the top left hand corner of the A4 sheet of paper (so the page occupies about a quarter of the page area that it should).  I'm running Windows 11 and have installed Microsoft 365 for the first time on any PC (this small print problem is apparent when printing Word docs etc... but also when printing emails from a non-Microsoft email platform. So I'm guessing this issue is probably not related to Microsoft 365).

A few days ago, I reinstalled the printer driver from the HP website - and the printer was able to print correctly. However, the next day it was back to printing in just the top left hand corner of the page (and shrinking the text to fit that small space). I have since tried to install the driver several times, but it makes no difference - the issue persists.

I've also tried setting the paper size and checking other settings for the printer.  All seem OK.

Also tried setting the printer up to just print when connected to USB (ie not using wireless).  However, during the driver set up process, the set up wizard is totally unaware that the printer is plugged into the USB on the PC... so the set up process won't proceed as it thinks I've not attached the printer

Is Windows 11 selecting some kind of default printer driver and overriding the installed HP driver?  (NOTE:  I've got other HP laptops running Windows 11 and they seem to be able to print OK.  However, none of those other laptops are currently running Windows 365)

Many thanks for your help.

Could my problem be as a result of the installed printer driver being 'Microsoft IPP class driver'?

Strange thing is yesterday - without me changing anything - the printer started to print at normal speed and it printed correctly (ie normal font size and filling the A4 page, not just the top left quarter).  But then, for no apparent reason, it went back to printing small text and printing the entire page on just the top left quarter of the A4 sheet of paper.

The change from incorrect printing... to correct printing... to incorrect printing again... appeared to be totally random.  But I don't think that's how computers work. Something must have happened to change its mode of operation.

Any ideas welcome.

Thanks.
