Question:
- Epson TM-88 Dipswitch Settings
- Epson TM-88 Printer Configuration
- Epson TM-88 Calibration
- How do I see my Epson TM-88 printer settings
Environment:
- Epson TM-88 Printer
Answer:
The Epson TM-88 has physical dip switches that control some of the printers settings. Some of these dip switch settings are used for serial communication to the meters. These communication settings need to match the printer communication settings that are set on the meter (Handshaking, Parity Check, Parity Selection, Baud Rate).
*Note: Sometimes the default printer settings do not match the meter's default settings Or the printer communication settings may have been changed on your meter.
The dip switches are located on the bottom of the printer under a service cover.
These dip switches can be difficult to see what position they are in. You can print a Configuration Ticket to see exactly what position the dip switches are on.
