I have used a label printer on serial port with comlpt library, and now, I have to use a Zebra USB label printer. I used to send commands by COM/LPT.
How can I send a string through USB port to a printer (for example: "^XA ^FT96,431 ^CI0 ^A0B,54,93^FDEcopulp^FS ^XZ") using your library?

Hello

Please take a look at USBIODemo demo. It allows to select pipe and make write and read operations.

Hello

I'm sorry, but I do not have good news for you.
Because we can not reproduce problem on our side.
We need real device for catch error.
Your device provides interrupt pipe, but all our test devices provide bulk pipes.

Can you describe more your device, possible we can design it here if it is not too difficult.
Possible you can ship device to us and we will try resolve problem.

I ordered a batch of USB devices before, but before that, I didn't know anything about this.
