Paxar TC6032EM - Manual (Page 13)

Using Batteries 2-5
♦ The battery should be charged immediately for either long-term storage
or after the battery has been exhausted from a printing session.
Frequent charging will actually prolong battery life and has no negative
effects such as memory issues.
♦ The printer uses battery power even when the printer is not printing.
Remove the printer’s battery and place on a charger when the printer is
not in use.
Many factors affect your battery’s performance, including the quantity of
labels printed, intervals of batches printed, percentage of black per label,
and power management.
