Interface SpecificationsNote:

All interface conditions are based on TTL level. Both the rise and fall of each signal must be less than 0.2 microseconds.

Data transfer must be carried out by observing the ACKNLG or BUSY signal. (Data transfer to this printer can be carried out only after the receipt of the ACKNLG signal or when the level of the BUSY signal is LOW. The relationship between BUSY and ACKNLG can be changed using SelecType. See Chapter 4.

The column heading “Direction” refers to the direction of signal flow as viewed from the printer.

“Return” denotes the twisted-pair return to be connected at signal ground level. For the interface wiring, be sure to use a twisted-pair cable for each signal and to complete the connection on the return side. These cables should be shielded and connected to the chassis of the host computer and the printer. .

Interface timingThe figure below shows the timing for the parallel interface.

0.5µs min. 0.5µs min.

Varies depending on the Selec Type setting. 0µs typ, 5µs typ, 10µs typ, or ACKNLG Signal is not changed.
