Setting Data Error and Data Buffer options
This function allows you to select the handling of data reception errors (RS-232C only) and
to select the size of the data buffer (RS-232C and Parallel only).
Caution: The DIP switches are pre-set at the factory and should generally not be changed.
If you must change them, do so carefully to avoid changing other functions. Run the print
test to see the current settings for this function. See "Testing The Printer" in chapter 2.
