Damaged or incorrect I/O cable.
Several problems can cause data loss or communication problems on the printer. Data
loss can result in printing errors or missing field data.
Your printer is a serial ASCII device. It communicates with the host through an ASCII
serial communication I/O port. Hardware handshaking involves the use of a hardware
wire. Software handshaking involves a two-way datalink between the devices. The two
devices communicate with each other without losing data through the use of
handshaking. The printer sends both forms of handshaking simultaneously when the
printer's input buffer is full. Any loss of data can cause printing errors.

Solution
Switch to approved media or clean the printhead and
platen roller as described in Chapter 3, "Maintaining
the Printer."
Edit the format to ensure that the text fits on the
label.
Properly position the label mark sensor. For help, see
"Adjusting the Label Mark Sensor" in Chapter 5.
Solution
Make sure the printer's serial port settings match those
of the host. Print a software test configuration label as
described in Chapter 1 to check the serial port
settings.
Check the connections at both ends or replace the
cable. See Appendix C for cable information.
