reflected in the Status Sheet and EJL read-back, the actual change takes effect after a warm boot or after the power is
turned on again.
Parallel I/F
Allows you to activate or deactivate the parallel interface.
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 68.
❏ Resetting the printer erases all print jobs. Make sure the Ready light is not flashing when you reset the
printer.
