Hello, I have a multifunction HP ePrint wireless router connected by telephone .
In the router quick guide explains how to link the router with peripherals through what they call WPS ( guess that why they call it as router , but I do not know 100% , it may be generic).
Then , on the same printer settings you must have something setup for this purpose so that :
Check that your modem available that WPS option (mine is old, so it is very likely that you have also have)
If you do not have the printer manual , look it up on the manufacturer's website that you can download in secure PDF .
If you say you do not have wifi in the printer, for then imagine that you can not do the link between devices. For screenshots I've seen of the Multifunction , I see no icon associated with the wireless antenna . If they bring the top models that you have.
To print texts going great . I have not tried with images, may delay something , viz. Anyway, I hope you serve the response.
