Signal descriptions
-STROBE
When the printer receives a low -STROBE pulse of width greater than 0.5~~ from the
computer, it reads the data from the interface and makes the BUSY line high.
DATA
These signals are the 8 bits of parallel data from the computer. A high level indicates a
logical 1; a low level, a logical 0. The printer reads the DATA lines when a -STROBE
pulse is received.
-ACKNLG
The ACKNLG pulse tells the computer that the printer has read the data from the
previous -STROBE pulse. An -ACKNLG pulse is also generated when the printer is
powered on, or at the completion of printer initialization by an -1NIT signal requested
from the computer.
