Quick Start Guide

This Quick Start Guide gives instructions for connecting the printer, installing the software, and loading the labels. For complete information about programming and using the LabelWriter SE450 printer, refer to the LabelWriter SE450 Technical Reference Guide available on the Developers Program page of the DYMO Web site (www.dymo.com).

The LabelWriter SE450 label printer is primarily intended for applications limited to sending simple ASCII print data and Escape commands for printing from computers or devices using the serial or USB connections. In addition, printer drivers are included for printing from a Mac, Windows, or Linux system.

The software CD included with the printer includes the printer drivers for Windows, Mac, and Linux, and the full DYMO Label v.8 software installer. However, when used primarily as an ASCII printer, the drivers may not be required by your system.

LabelWriter Printer Features

Your LabelWriter printer is a direct thermal printer and does not use ink or toner. Instead, the printer uses heat from a thermal print head to print on specially treated labels. Labels are the only supplies you will ever need to buy.

The form-feed button on the front of the printer advances a single label.

The status light visually shows the current state of the printer:

Solid blue - USB cable is connected and printer is ready to print.

Solid green - Serial cable is connected and printer is ready to print.

Dimmed blue or green - printer is in power saving mode.

Flashing red - Labels are not loaded properly or the label roll is empty.

Flashing green - Printer is in configuration mode. Refer to the Technical Reference Guide.
