Table 2-9 Conditions for canceling receive buffer BUSY state
Conditions to cancel receive buffer BUSY
state
BUSY state canceled when 26 bytes or
more remain in receive buffer
Note:
With the TM-T88III, the DIP SW2-5 setting is enabled only when DIP SW1-2 is set to OFF and the
receive buffer is set to 4KB.
With the TM-T88II, be sure to set DIP SW2-5 to OFF before use. Otherwise, the printer may no longer
function correctly.
When the TM-T88II is used or when TM-T88III is used with DIP SW1-2 set to ON, the BUSY state is
canceled when "26 bytes remaining in receive buffer" are reached regardless of the setting of DIP SW2-5.
Do not change the settings of DIP SW2-2 and SW2-6. Otherwise, the printer may no longer function
correctly.
