/*
 * Example of calling ImageMagick 'convert' to manipulate an image prior to printing.
 * 
 * Written as an example to remind you to do four things-
 * - escape your command-line arguments with escapeshellarg
 * - close the printer
 * - delete any temp files
 * - detect and handle external command failure
 *
 * Note that image operations are slow. You can and should serialise an EscposImage
 * object into some sort of cache if you will re-use the output.
