Printing Errors or Lights & Stuck Print Jobs

this printer has always had issues retaining a permanent online presence via wireless.  however, it now needs resetting every day.  It appears offline no matter which device tries connecting be it a Windows PC or Windows 10 or 7.  Mobile devices with the HP app installed all have the same connection issue where the printer appears off-line.  The print & scan doctor is useless in this regard as it just keeps telling me the printer is no turned on.  Well it is and the router and printer are both telling me the device has a valid ip and is connected.   In addition scanning will sometimes work when this off line print error occurs.

To get rid of the error only the printer needs to be restarted, but the solution is only temporary, lasting about one day.

A direct ethernet connection to the router is not an option due to the locations of the two devices, but I could temporarily reloacte the printer for testing if necessary.

I've tried all the various suggested solutions on the HP forums for what appears to be a common problem.  None have solved the issue. 

Restaring the printer gets it back online, but it's only temporary.  the device is still within warranty so if this is a fault I'd like to know so I can submit a claim with the retailer.

For info my modem/router is TP-Link TD-W8980 just in case there is any documented incompatibility issues between this printer and this router.  I've had the router for about 2 years without issue.  I've had the printer for 10 months.
