Setting Data Error and Data Buffer Options
This function allows you to select the handling of data reception errors and to
select the size of the data buffer.
Caution: The DIP switches are set at the factory to predetermined settings and
should generally not be changed. If you must change the settings do so carefully
to avoid changing other functions. Run the print test to see what the current
settings for these options are. See “Print Test” later in this chapter.
1. Open the front cover and note what the current DIP switch settings are.
2. Set the DIP switches to the settings in the table you want for data reception
errors and the data buffer.

Ignoring/Using the Carriage Return
This function allows the printer to ignore or use the Carriage Return (Hex 0D)
command depending on the application. Some applications expect the command
to be ignored while others use the command as a print command.
