Inverted logic:
signal is active
when low.
In Host Busy when Advanced Status is On.
15-17 N/A LOGIC GROUND Logic Ground
18 N/A VCC 300 mA of 5 V +/ - 5%

In Driven by the host.
19–30 19–35 GND Return These pins are grounded signals used as twisted pairs with the
data and control signals. GND is often called a logic ground, and a
fusible link isolates it from chassis ground to offset any large
ground shifts when the printer and computer are on different
circuits.
31 14 INIT*
signal is active
when low
In The rising edge of a negative pulse on this line causes the printer
to initialize. The printer synchronizes this function with the
received data. On the falling edge of INIT*, the printer drives the
BUSY interface signal active. On the rising edge of INIT*, the
printer:
• Prints all received data
• Displays RESET
• Initializes
• Deactivates the BUSY signal
To disable INIT* processing, set
Honor Init to Off from the printer
operator panel or through MarkVision Professional. Refer to your
printer user documentation for more information.
32 4 ERROR*
Inverted logic:
signal is active
when low
Out This signal indicates a printer error condition. The signal level
becomes low when the printer is:
• In paper exception status
• Not ready because of an operator panel command to stop
• Not ready because of a software command to stop
• Not ready because of a software command for manual feed
This signal is activated approximately 5 seconds after one of the
above conditions sets BUSY.
33–35 N/A LOGIC GROUND Not used.
