Introduction
The TM-U200D and TM-U200PD are one-station printers for ECR and POS use which can be used for printing the
results of weighing or measuring.
The main features of the TM-U200D and TM-U200PD printers are the following:
❏ High-speed printing through logic-seeking control
❏ Excellent reliability and long life due t o use of two stepping mot ors, one for mo ving the carri age and one for pape r
feeding
❏ Flexible paper feed setting permits printing in accordance with any user-defined format
❏ Command protocol based on ESC/POS, a widely used standard
❏ Built-in drawer kick-out interface provides capability to drive two drawers
❏ Selectable character fonts (7 x 9, 9 x 9)
❏ Semi-automatic paper loading capability
❏ AC adapter (included) provides compact power supply
❏ Compact and light in weight
❏ Automatic Status Back (ASB) function to automatically send printer status changes.
❏ Two-color printing. Black and red colors are selectable. (2-color Print Version only)

Reverse communication (Printer Host): Nibble or Byte Mode
Reverse Mode (Data Transmission from Printer to Host)
The STATUS data transmission from the printer to the host is proceeded in the Nibble or Byte
mode.
This mode allows data transmission from the asynchronous printer under the control of the
host.
Data transmissions in the Nibble Mode are made via the existing c ontrol lines in unists of four
bits (Nibble). In the Byte Mod e, data transmissions are proceeded by making the eight-bit data
lines bidirectional.
