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.

Loading Labels
Important!
In order for the labels to feed properly during printing, the labels must be loaded with the left edge of
the label inserted against the left edge of the label feed slot. See Figure 8.
To load a label roll
1Press the form-feed button to eject the labels that
protected the printer during shipment.
2Open the top cover and remove any packing material
inside the label compartment.
3Remove the label spool from inside the top cover and
pull the spool guide from the spindle.
4Hold the spool spindle in your left hand and place the
label roll on the spindle so that the labels feed from
underneath and the left edge of the label roll is firmly against the side of the spool. See
Figure 5.
5Slide the spool guide onto the right side of the spool and press the
guide tightly against the side of the label roll, leaving no gap
between the roll and the spool. See Figure 6.
NOTE To ensure proper feeding of labels during printing, the label roll
must fit snugly against both sides of the label spool, with no gaps.

6Insert the label spool into the slot in the printer cover with
the labels extending from underneath the roll. See
Figure 7.
7Align the left edge of the label with the left edge of the
label feed slot and insert the label into the slot.
The printer automatically feeds the label, stopping at the
beginning of the first label.
If the printer does not feed the labels, make sure the
first label is fully inserted and then press the form-feed
button on the front of the printer.
If the first label on the roll is not a full label, press the
form-feed button to eject the partial label.
