TM Virtual Port Driver

The TM Virtual Port Driver Utility is available from Epson websiteepson.com (technical resources).

Features of the Virtual Port driver include:

  • Application Friendly - You can use a TM printer with a USB or Ethernet interface TM printer without altering existingapplications
    that specify the serial / parallel port using ESC/POS commands. Even in an environment ofY-connection/pass-through connection, replacement with a USBinterfaceprinter can be performed without altering the existingapplication. When pass-through connection isused, the connection pattern will be changed to Y-connection.See 'Change from Pass-Through Connectionto Y-Connection. - USB' .

  • Simple Replacements- If a TM printer malfunctions and isreplaced by an identical or compatible model, the communications
    module automatically detects and reconfigures settings, sodrivers and applications do not need to
    be set-up again.

  • Serial Line Emulation - The virtual portincludes serial port signal line emulation. In cases where the serial signal line is controlledby the application, replacement with a USB interface TM printeror customer display can be performed without altering theapplication.

  • Compatibility with Ethernet Interfaces - If EpsonNet Config or TMNet WinConfig isinstalled on the computer, the IP address of the TM printer can
