• Device B signals it is ready by pulling up the Ready signal. This must remain high
for at least 50 ms. When the Ready signal is pulled down while the printer is
printing, the printer will pause and behave exactly the same way as if the user
presses the Pause button on the control panel. The printer remains in Pause
mode until the Ready signal is pulled up again for at least 50ms.
• The printer prints and pulls down the signal when printing is completed.
• No printing occurs whenever the Printer Error signal is pulled low.
