The image cannot be printed completely

[fecherwu]

Hello, according to your method, I tried to write and print, but when I wrote the background, there was a branch when printing. How can I solve the problem of incomplete printing caused by the branch?

Try this :)

device.open(function() => {
  const noLineSpacingCommand = Buffer.from([0x1b, 0x33, 0x00]);
  device.write(noLineSpacingCommand);
  printer.raster(image);
