  • Page 193 Chapter 1: General Description Timing chart The parallel interface transfers data in one direction only: from computer to printer. The data path is 8 bits wide. The printer and the computer synchronize data transfer with the interface signals, -STROBE, -ACKNLG, and BUSY. When the computer is ready to send a byte of data to the printer, it puts the byte of data on the data lines (DATA 1 through DATA 8).
