/*
 * This example shows Arabic image-based output on the EPOS TEP 220m.
 *
 * Because escpos-php is not yet able to render Arabic correctly
 * on thermal line printers, small images are generated and sent
 * instead. This is a bit slower, and only limited formatting
 * is currently available in this mode.
 * 
 * Requirements are:
 *  - imagick extension (For the ImagePrintBuffer, which does not
 *      support gd at the time of writing)
 *  - ArPHP 4.0 (release date: Jan 8, 2016), available from SourceForge, for
 *      handling the layout for this example.
