Hi James,

Correct if I can intercept the data from the computer then have it go to two places 1) USB Printer 2) Generic Com Port Printer.  Is this possible?

This would be perfect.

Thank you, USB Newbi

[to FIFO/capture the USB data and sent to it. Then pass the data to the actual USB Espon printer and out to the USB to serial converter shield or have it send the data out as generic text?]

Hi PaulS,

If the Windows computer default printer is set to print to a USB Espon printer... Could the Audrino board be connected to the USB to  FIFO/capture the USB data and sent to it.  Then pass the data to the actual USB Espon printer and out to the USB to serial converter shield or have it send the data out as generic text?

No admin access to Windows CPU.

Sometimes our clients don't have access or won't give it to us.  So the only way we could capture data would be from the data coming from the default usb printer.

Again, thank you for your help. 

Hi All, I am very new to microcontrollers and arduino's products so please bare with me.  Being that this has to do with USB and how it communicates with the host I am not sure this will work in the first place. 

Situation:
Have computer with USB Epson printer.  No admin access to Windows CPU.

Problem:
Need to take the USB cable from Window's CPU and have not only print to the Epson printer but also convert the same data and spit is out to Serial (com port).

 
I would like to know if this is possible and if so how?

Thanks! KG
