Dip Switch Reset for Star Micronics TSP100 LAN Printer

Step 1.
Turn off your printer and unplug the power cable.

Step 2.
Leave the printer still connected to your router. Your router should not be powered off.


Step 3.
Turn your printer over and locate the small dip switch panel on the underside of the printer.

Step 4.
Using a Philips head screwdriver, remove the single screw. The panel sometimes is screwed on very tightly by the factory and can take some effort to unscrew. It is very important you have the correct sized screwdriver to prevent damaging the screw head when applying pressure.



Step 5.
Assuming the printer is oriented with the back of the printer (the side with the power, cash drawer, and Ethernet ports) in the '12 o’clock' position, your printer dip switches will be all set to the left side.

Step 6.
Using a pen tip, set the dip switches to the opposite side (i.e. the right side).

Step 7.
Screw the dip switch panel back on.

Step 8.
Turn the printer back to its upright position.

Step 9.
Make sure the power switch is still off and plug in printer into the wall socket. Make sure the powered router is still connected.



Step 10.
Put your finger on the Feed button and click the power switch on. Do not release the Feed button until your printer starts to make a sound. Release the Feed button when your printer starts to make a sound. It will print 2 papers.

Verify the second paper indicates a DHCP IP address, like '10.0.1.2'.

Step 1.
Turn off your printer and unplug the power cable again.

Step 2.
Turn your printer over and reopen the small dip switch panel.

Step 3.
Set the dip switches back to their original position (meaning, the opposite of what they are currently).

Step 4.
Screw the dip switch panel back on.

Step 5.
Power on your printer.
