question about my epson artisan 730 printer (connecting another printer to epsons usb port)

Hi I have a networked printer, the epson artisan 730,

I have a thermal printer for shipping labels that I often use, so I was wondering if it is posable to connect the thermal printer to the epson USB, to give the thermal printer wireless capabilities as well?


and under the tech specs it says it has the following connectivity specs:

Wireless 802.11 b/g/n
Ethernet – 10/100,
Hi-speed UsB, PictBridge™
EPson Connect Email Print
AirPrint enabled
Google Cloud Print ready

Then I go to "my computer" and it shows two netoworked drives, one is the built in card reader, the other says ""usb storage on epson".

So I dont know is thats what the usb storage is for or not. I  tried to find the answer on epsons site (provided below) but could not find anything. Here is the link to the printer however:
