7) Notes on resetting the printer through the interface

2.1.3 Reception of status from the printer through the bidirectional parallel interface
In the bidirectional parallel interface specifications, the printer status transmission is available by using
the both-way communication facility in the Nibble/Byte Modes in accordance with the 1284.
In this case, different from in the RS-232 serial interface specifications, the real-time interruptions from
the printer to the host are disabled and thus precautions must be taken to the followings.
1) Allowable capacity of the printer internal buffer is 100 bytes (except ASB status). The status signals
exceeding this capacity will be discarded. To prevent possible loss of status, the host shall be ready
for data acception (Reverse Mode).
2) When ASB is used, the host is preferably in the wait state for data acception (Reverse Idle Mode).
When this state is not available, the host shall enter the Reverse Mode to always monitor the
presence of data.
3) When ASB is used, preference shall be given to the ASB status for transmission over the other status
signals. Any accumulated ASB status signals left for transmission from the last to the newest ASB
status transmission shall be transmitted together at a time as one ASB status showing the presence of
change, followed by the latest ASB status.
