Connecting printer to new router

[debbedy377]

I have a HP Deskjet 3636 printer and this week had a new router.  My printer appears to be constantly off line and when I have looked it up it says I need to connect it to my new router.  It tells me to press the wifi button on the printer and the WPS button on the router my router however only has three buttons - power, internet, wifi, voice.   No WPS button.  Can anyone help before I go out at weekend and spend £60 on a new printer

@debbedy377 every Sky hub has a wps button but on the upright models they are easy to miss they are on the narrow right hand edge..

This did not work. ??

I guess my printer is too old for new router so have shelled out £80 for a new one. Arriving tomorrow.
