would definitely be 2 things that come to mind

1 check and recheck that your router (eg its box or manual) would show if it has this feature which is shared printing usually via the USB port on the wifi router - but dont just take for granted that just bcos your wifi router has usb ports it neans that it has printing features

2 also to do with the wifi router assuming that you have checked and confirmed point 1
then you will need to separately install a program on your laptop or desktop to enable wifi router usb port\
recognision for printting eg take this router as an eg



not only you need to START the service on your wifi router after plugging in the usb cable to your printer

but you will also need to read that manual that came in your wifi router box or online as shown

then download an initializstion program to handshake a protocol for the usb shared wifi printing to start

of course these are all very general and only an example but yours will be more or less this way too\\

\\ so do your due diligence and with this we wish you luck
