Thanks.Recent printers have a standalone WIFI.
Also, your phone can be it’s own router if it supports a mobile hot spot and the printer should be able to connect to that.
According the the USB spec a slave device can not power the bus. Power must be at the host end only. If your printer has OTG capabilities then it will act as a host and will be allowed to power devices connected to it. Normally (actually probably never) a printer has no use for the OTG capability and therefore will only work in slave mode... as in it needs to be connected to a computer.Hi. I believe USB-B jacks do not provide 5V for a RF unit to work powered by it. Once I hook it to 5V internal rail in a printer to do some experiment.

I have 6 like this. Never seen it for USB-B
Wi-fi direct is a standard and is supported by many printers that have a native WiFi interface. The odd thing is, so far as I can tell, there is no WIFi/USB print server offering it. It seems a no-brainer, but I can’t find one.It's my understanding that the Wi-fi Direct service is designed to offer peer-to-peer wifi connection without a supporting network.
My HP printers offer it in the setup menu.
Then you are asking for the wrong thing. Why would WIFI be used to connect to a USB interface on the printer? What you need is an OTG adapter for the phone. I use one to connect my phone to a MIDI synth. It provides USB host capability to the phone.Thanks.
Well, the intention is to add to an older printer the feature of printing direct from a cell phone, not to buy a modern new printer.
No more complications please, no routers, no hotspots, no access points, no bridges, no quick modes, adhocs, peer to peer, blueteeth and what else is out there... It is sickening. Just a plain 'walkie-talkie' link for data !
If he want’s wireless, then that is only half the solution. He’ll also need a wireless USB extender.Then you are asking for the wrong thing.
