/*
 * This is an example of printing chinese text. This is a bit different to other character encodings, because
 * the printer accepts a 2-byte character encoding (GBK), and formatting is handled differently while in this mode.
 *
 * At the time of writing, this is implemented separately as a textChinese() function, until chinese text
 * can be properly detected and printed alongside other encodings.
