Overview
This specification describes the extended I/F specifications for the TM-C7500 series / C7500G series. Please
develop your device to match these specifications.
Functionality
Using the extended I/F signal allows the user to perform synchronous control of the printer and external
devices and to check the printer status.
Signal transmission between the printer and external device uses a D-Sub15 cable.
Also, use a USB cable or Ethernet cable to send ESC/Label commands, which set the operation for the extended
I/F, from the host PC.

Target options
The following external devices can be connected.
• Rewinder (including large diameter roll)
• Unwinder (including large diameter roll)
• Other than above listed options needed to work with Color inkjet printer.
