On the 1460 printers (Version 3.0 and higher), status byte #3,
bit 3 is "on" as soon as a label is printed and is placed on the
Tamp Pad. The bit is "off" as soon as the Tamp Arm applies
the label. This bit is "on" when the Tamp Arm returns to the
home position and another label is placed onto the Tamp Pad.
The bit is "off" if no label is placed onto the Tamp Pad.
The following graphics can be used as a quick reference for
the Status of Byte #2 and Byte #3. Byte #1 is the
non-printable user-defined ENQ character.
