Star Thermal Printer

Fork of Klemenn1337/node-thermal-printer with more features for Star thermal printers. For added features see Added Features Section

Installation

npm install star-thermal-printer

Linux specific

Linux requires build-essentials

sudo apt-get install build-essential

Browser specifics

When using inside a browser, the network interface will not work as browsers do not allow opening TCP sockets.
You still need to instruct the compiler to ignore node dependencies. For webpack, it can be done like this:

new webpack.IgnorePlugin({
  resourceRegExp: /^fs$|^net$/,
}),
