1. Introduction

DPL emulation allows TD-4T and TJ Printers to interpret DPL commands. To use this feature, change the
printer settings as described in Section 2

.

2. Printer Settings

The TD-4T and TJ Printers have built-in paper settings that are necessary to perform printing operations
(position detection). The settings are saved in the device’s flash memory so they are retained even if the
power is turned off. Before using the DPL emulation, printer settings (such as the paper size and type) must
be set using the Brother Printer Management Tool (BPM):

a. Start the BPM.
b. Click the Printer Function.

Select the calibration sensor, and click t he Calibrate.

c.

d. Click the Printer Configuration.
e. Select the FBPL tab.
f. Set the print operations you want.
g. Check if the paper size settings for each printer lang uage is correct.
h. Click Set.

The paper size and type can be set using the FBPL paper setting command (refer to FBPL Command
Reference).
