Signal Descriptions
Media Out (Label Out)
Normally high. Low during a Label Out condition.
Error (Service Required)
Normally high. Goes low whenever the printer is stopped for a fault condition
that requires the user to perform an action to start again. This can be head
open, or any operation fault condition, etc.
End Print
Logic programmable via printer menu.
•
Mode 1. The default. Normally high. Low only when a label is being
moved forward.
•
Mode 2. Normally low; high only when a label is being moved forward.
•
Mode 3. Normally high; low for 50 milliseconds when a label has been
printed and positioned. Always high during continuous printing modes.
•
Mode 4. Normally low; high for 50 milliseconds when a label has been
printed and positioned. Always low during continuous printing modes.
•
Mode 5. Normally high. When the label has been printed completely, a
low going, 50 millisecond pulse is sent. (This mode shows the end of a
label print cycle, even in batch mode where labels are continuously being
printed.)
•
Mode 6. Identical to Mode 5, except normally low with a high going 50
millisecond pulse.
•
Mode 7. Normally high. At the beginning of a label being printed, the
output is set low. When the label is completed, the signal goes high. If
another label has started printing, the high signal stays high for 50
milliseconds. (This mode shows start and end of a label print cycle, even
in batch mode where labels are continuously printed.)
•
Mode 8. Identical to Mode 7, except normally low with high going signal.
NOTE: End Print applies only to printed labels. Output remains in normal
Data Ready/Off Line
Programmable via printer menu.
•
Ready Mode. The default. Low when sufficient data has been received to
begin printing the next label. High whenever printing is stopped after the
current label due to any condition causing the printer to pause or in the
absence of a label format.
•
Off Line Mode. Low whenever the printer is offline. High whenever the
printer is able to receive command streams and print labels.
Power On
Low when valid power is applied to printer, i.e., the main CPU is operating.
During power off, this should be in a high impedance state so an external
device can pull up to a voltage.
