TM-T88V Printer set-up guide

Remove the printer from the packaging and shipping protection. Ensure that you have all of the accessories and components you need to set-up the unit. Generally this will include a power supply, a data communication cable, and a roll of thermal paper.

Power Supply
All Epson printers that Beagle Hardware sells require a 24 Volt power supply (Epson models PS-170, PS-180). Please make sure you are not using an older 33V power supply that has the same pin pattern but won't work with any of our printers. Check for correct power supply here.

Printer Cable
Unless you've ordered a printer kit, the printer cable is not included with new or refurbished printers. With the exception of serial interfaces, all printers use standard (parallel, USB or Ethernet) printer cables available from an electronics store. Serial printers most commonly use a null modem type cable but may require a custom serial adapter. Consult your POS vendor for more information.

Install the correct type of paper into the printer.  Paper must be thermal and the correct width. To check if you have the right paper installed, check here.

Configuration Switches
Printers have DIP switches to set communications parameters and certain specific functions on the printer. These switches are located on the bottom of the unit behind a small removable metal cover held on by a single screw. If you are replacing a printer or have another in the same environment, it is best to match the settings on that unit to ensure the new printer is able to communicate correctly. For a listing of specific DIP Switch settings by model, please visit our main support page.

There is a multitude of Point-of-Sale software and configuration settings. For questions regarding the configuration of a software installation or the function of other POS hardware components, you should contact the manufacturer or your POS system directly. If you are changing a printer in an existing POS set-up the best approach is to make sure the DIP settings on the old and new printers match exactly (if they are the same model and series).

Initial Test
Turn on the printer. If the unit is hooked up correctly and ready to test, there will be no error lights showing.The lights should light solid and not flash. If lights are flashing check to see if the printer is setup correctly (ie. paper is installed, data cable connected, etc.). Run the self-test on the printer; turn printer off and power back on while holding down the Feed button. This test will print the settings of the unit and a series of test characters. If this self-test prints correctly, the problem is external to the printer. For instructions for specific printers, check here.

If you are having trouble getting the unit to print correctly, there are a number of different things you can try to isolate or solve the problem:

  • Reboot the computer/terminal and cycle the power on the printer. This step ensures that all of the software and settings are loaded correctly.
  • If you have another printer of the same model, swap that unit in and try to print. This will determine if the communications cable and computer/terminal are functioning correctly and if the problem is with that specific printer unit.
  • If you have a data cable of the same type (null-modem serial, parallel, USB, Ethernet), swap out the cable and attempt to print again. Data cables can fail rarely, and this step will determine if the cable is the issue.
  • If you are connecting to a Windows PC, you can go into the Control Panel / System / Hardware / Device Manager / Ports and determine if the port is functioning and the port number matches with the setup of your software.
  • Try our TM series troubleshooter for more detailed troubleshooting.
