The input buffer in this example has the length of 6 characters because the largest sum
of wildcards and offset is 6.
Beside the input buffer there is also a display buffer. The content of the display buffer is
what you see in the print preview of the main window of the JET2neo printer.
There are three rules regarding the input and the display buffer:
1. The input buffer has to be completely filled before its content is transferred to the
display buffer.
2. The print-out always reflects the content of the display buffer (what you see is
what you get printed).
3. The input buffer is emptied as soon as its content is transferred to the display
buffer.
The current display buffer will be printed with each PrintGo signal received unless you
have selected the <Check Double Prints> option.
With the <Check Double Prints> option activated you will receive an error message
when a PrintGo signal occurs before a new character string was received. So it is
granted that each character string is only printed once.
