+ * 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.
