Speed
Specifies the pulse width of the ACKNLG signal when receiving
data in the Compatibility mode or Nibble mode. When Fast is
selected, the pulse width is about 1 µs. When Normal is selected,
the pulse width is about 10 µs.
Bi-D
Allows you to specify the bidirectional communication mode.
When you select Off, bidirectional communication is disabled.
Buffer Size
Determines the amount of memory to be used for receiving data
and printing data. If Maximum is selected, more memory is
allocated for receiving data. If Minimum is selected, more memory
is allocated for printing data.
Note:
To activate Buffer Size settings, you must turn off the printer for
more than five seconds then turn it back on. Or, you can perform a
Reset All operation, as explained in "Reset Menu" on page 193.
Resetting the printer erases all print jobs. Make sure the Ready
light is not flashing when you reset the printer.
