Print buffers manage newlines and character encoding for the target printer. They are used as a swappable component: text or image-based output. - Text output (EscposPrintBuffer) is the fast default, and is recommended for most people, as the text output can be more directly manipulated by ESC/POS commands. - Image output (ImagePrintBuffer) is designed to accept more encodings than the physical printer supports, by rendering the text to small images on-the-fly. This takes a lot more CPU than sending text, but is necessary for some users. - If your use case fits outside these, then a further speed/flexibility trade-off can be made by printing directly from generated HTML or PDF.
