Great work on this project, it's been perfect for me!
I've been working with it a fair bit and have developed a few changes that help in use.
This change adds a helper Method to the PyUSBBackend which Detaches the Device from the Kernel and Reconnects - giving PyUSB Exclusive Access to the Printer.
I have found that this is required to fix: usb.core.USBError: [Errno 16] Resource busy.
Not sure if you're accepting PRs but happy to contribute the changes I've made which help with useability of the Library.
