Dear @dlwlrma00

The purpose of this library is just provide some helpful functions to generate binary data for TSC Printer.

The implementation in XPrinter.js is just for demo purpose and I'm not ensure that it will work for all variety TSC devices.

Look like you already fix this error in forked branch. Can you make a PR so I can merge it to my repo so a newcomers may get benefit from it?
