Converts a DataView, Uint8Array, or number array to a hexadecimal string with byte separator.

Converts a Uint8Array of length 2 to a 16-bit signed integer (big endian).

Converts a Uint8Array of length 2 to a 16-bit signed integer (big endian).

Count non-zero bits in the byte array.

For split mode:

Data splitted to the three chunks (last chunk sizes can be lesser, base chunk size is printhead size / 8 / 3) and non-zero bit count calculated from each chunk.

If data size is more than printheadPixels / 8, only total mode can be used.

For total mode:

Return total number of pixel in little-endian format: [0, LL, HH]

For auto mode:

By default split mode used. If it is not available, total mode used.

Converts a DataView object to an array of numbers.

Converts a DataView object to a Uint8Array

Find check array has subarray at index

Converts a hexadecimal string to a Uint8Array buffer.

Checks if the browser supports Bluetooth functionality.

Checks if the browser supports the Web Serial API for serial communication.

Converts a given number to its hexadecimal representation.

Asynchronously pauses the execution for the specified amount of time.

Converts a 16-bit unsigned integer to an array of two bytes (big endian).

Converts a 32-bit unsigned integer to an array of two bytes (big endian).

Compares two Uint8Arrays to check if they are equal.

Converts a Uint8Array to a string using TextDecoder.
