Security warning

[Piwackett]

I own an HP Officejet Pro 6968 All-in-one printer.  I recently purchased a new Imac and in adding my printer to my computer I was having some issues with it recognizing my computer.  I reset the pirnter to factory default settings and started over. It seems to work ok now, but I did get a Security Warning stating "The printer "HP OfficeJet Pro 6960 (517676) " appears to be a different printer than the previously used printer with the same name or the connection may not be trustworthy. If this is expected, tap "Continue"  I've also always thought it kind of odd (ever since I purchased the printer a number of years ago) that the model number that shows on my computer is not the same as the model number actually on the printer. Sorry for the lengthy description, but I just want to make sure I covered all the bases.  But my question is...is there a fix for this Security Warning, or should I be concerned about it?  TIA

I have just had a security message trying to print from phone saying it appears to be different from the previously used printer with the same name or the connection may not  be trustworthy. Has anyone else
