I would avoid printing using the USB interface at all. Save the .GCD file on the included SD card and print from that. In the end it’s way less hassle and avoids several failure modes. I have never had a print fail while using an SD card as the source. I have had a few fail when using a laptop, mostly due to communication glitches, windows updating, or any other random cause that I was never able to figure out.
The only thing i use the usb interface for now is updating firmware.
Using this method, you could conceivably print on a unlimited number of printers from just one computer. I’m also pretty sure this is how Lulzbot prints all the parts for their production parts.
