I don't think printer sever can work with a phone because there is no driver for your printer.

tq vivian....
but with the wifi printer, I can detect that printer...
so I bought tl-wps510u to make my printer become wifi printer...
and it work with my pc but it can't with my phone...
is there any sw or driver to install to my phone?

Actually, before we use printer to print, we need to install printer driver on PC and make sure it is working properly with PC first.
Maybe you phone can detect it, but you need to confirm that there is printer driver and your phone can print without WPS510U.

Hi,
I am able to connect my Android phone with printer thru WPS510U.
All you need just install android mobile printing for a specify brand ( for my Samsung printer, I installed samsung mobile print app.) After that add device manualy in mobile print app. Input the ip as you configure to the WPS510U. Data type : RAW. It's work very well with my Samsung ML-2160.

I've connect this device in this mode:
Configured printer server for access Infrastructure mode access to Android AP in tethering mode

First step : Read the guide FAQ ID: 242 - How to configure the TL-WPS510U working on Infrastructure mode through its web page

1) On Android device enable tethering without a password - SSID : AndroidAP
2a) connect a notebook (ip 192.168.0.11) with (adhoc mode) printer server and set this ip (192.168.43.200/255.255.255.0 tethering class) reboot
2c) connect a notebook (ip 192.168.43.201) with (adhoc mode) printer server and configure infrastructure mode to SSID AndroidAP reboot
2d) connect a notebook (DHCP) to AndroidAP and connect to print server (192.168.43.200) and change TCP/IP to DHCP mode reboot
3) Now with PrintShare App from Google Play found it!

Roc'n roll!
