S4M printer communicating via the RS232 Serial Interface
Serial communications requires that all data settings are matched between the host and the printer.
A NULL Modem Cable must be used between a PC and the printer DB9 interface. Read More>>

An RS232 communications interface is included with the printer and allows for serial communications between the host and printer. All parameters must match to work properly including the Host Handshake setting.

1. Connect the Serial Cable to the printer and host (connection to a PC Com port requires a NULL MODEM)
2. Create a test file label format using the programming language your printer supports (V58 is ZPL, E50 is EPL)
3. Send the file to the printer using a send function of your application or utility.
The printer should respond to the test format.
If the printer does not respond
- Verify the data is getting to the printer
- You are sending a complete label format using the compatible printer language
- Verify the Host and Printer are configured for the same Baud, Data Bits, Stop Bits, and Parity. Print a configuration label to check the printer settings Read More>>
