About the LabelWriter 550 Series Printers
The LabelWriter 550 series printers (LabelWriter 550, 550 Turbo, 5XL) are high-performance, low-cost
printers used for printing mailing labels, postage, file folder labels, barcode labels, and more. The
LabelWriter 550 and LabelWriter 550 Turbo printers have a 57 mm wide print head. The LabelWriter 5XL
has a 101 mm wide print head. All printers have 300-dpi print head.
The 57 mm wide thermal print head uses 672 individually addressable dots to form individual raster
lines of data at 300 dots per inch across the print head—the 101 mm wide print head uses 1248 dots.
Both use 300 dots per inch in the travel direction as directed by the print control data. Because they use
specially treated, heat-activated paper, the printers require no ink, toner, or other refills.
All 550 series printer models connect to a host computer through a standard full-speed USB 2.0-
compatible interface. There are no built-in fonts. The host computer is responsible for sending
commands and data to the printer to form each individual raster line of data. This is generally
performed by printer drivers in the host computer that convert the image of the label into the proper
command and data stream required by the printers.
LabelWriter 550 Turbo and 5XL printers can connect to a host through a 10M/100M Ethernet LAN
connection.
Print Data
Print data is encoded in strings of 8-bit bytes.
The default value for LabelWriter 550 and LabelWriter 550 Turbo printers is 84 bytes per line (84 * 8 =
672, the number of dots in the print head)—for LabelWriter 5XL, 156 bytes (156*8=1248, the number of
dots in the print head). The host-computer can send fewer bytes than the maximum within the <esc> D
command. The control electronics do not check the validity of the new value. Therefore, it is the
responsibility of the host-software to send only those values which are valid for the width of the print
head.
The Bytes-Per-Line variable is held by the control electronics until they are changed by a new command
sequence, is reset to default values by a power-on reset, a software reset command, or after the end of
a print job.
Print Job Structure
The print job structure consists of the following parts:
1. Print Job Header
2. Label Structure
a. Label Header
b. Label Data
c. Label Trailer
3. Print Job Trailer

Label Structure
The Label structure has the following 3 parts:
1. Label Header
2. Label Data
3. Label Trailer
The structure must be present for each label that is to be printed in a single print job.
Label Header
The Label Header is the beginning of the label structure. It is mandatory to have <ESC n> to indicate the
label index and <ESC D> to indicate the start of the label print data. See the “Printer Commands” later in
this document for more details.

Label Data
The Label Data is the data that will be printed out onto the labels. It is an array of binary data bytes. It’s
size equals width*height. ‘0’ means a dot is not printed; ‘1’ means a dot is printed. The most significant
bit of the first print data byte represents the lower pixel of the first line. See the <ESC D> command in
the “Printer Commands” section later in this document for more details.
Bytes per line= roundup( (height * Bytes Per Pixel) / 8)
Label Trailer
The Label Trailer is end of the label structure. It moves the label to either the print head of the next label
or to the tear position. It is mandatory that <ESC G> (Feed to Print Head) or <ESC E> (Feed to Tear
Position) be used in this section.
Mandatory Commands

Print Job Trailer
The print Job Trailer is the final part of the print job structure. It is mandatory to use the <ESC Q>
command to end the print job.

Data Synchronization
After the printer receives a Lock Request from the host, the printer will respond. (See Print Status
Response section for details.) The host (Host-A) will be granted a lock only if the printer is not printing.
Once the lock is granted, the Host-A will begin to send the print data for the current print job with the
<ESC s> command. (See “Print Job Structure” section above for additional details). If another host
(Host-B) requests the printer’s status, the printer will respond that it is printing. No other host can
interrupt the print job of Host-A.
The data goes into a buffer and the printer sorts through the various commands applying the print job
settings.
The data between the height value in the <ESC D> command and before <ESC G> or <ESC E> is the data
that will be printed, also referred to as print data.
Label Positioning
A motor-driven platen, which acts as a pinch roller, controls label movement within the printer. The
control electronics track label travelling positions. An infrared LED photocell detects the top-of-form
sense hole that is located between labels. The absolute positions of the label and the tear bar are
calculated based up the reading of an infrared LED photocell sensor.
Top-of-Form Sync
At power up, label position is always assumed to be correct. If an Out of Paper condition is detected at
power up, user requires to press form feed button and the stepper motor will advance until label load to
Top-of-Form tear bar position.
Label Length
The label length is determined by the SKU data found on the NFC Tag.
If the roll has continuous form paper the Form Feed command (<esc> E) is changed to feed enough dot
lines to allow for the last line of print data to extend past the printer tear-bar.
The host can use <esc> L to Set Length to Continuous Stock. See more details in the “Printer Commands”
section later in this document. Only authentic Dymo labels with a valid NFC Tag can be used for printing.
Label-Movement Commands
There are two label-movement commands implemented in the LabelWriter 550 Series: Form Feed, Short
Form Feed. These commands operate as follows.
Form Feed Command (<esc> E)
This command advances the most recently printed label to a position where it can be torn off. This
positioning places the next label beyond the starting print position. Therefore, a reverse-feed will be
automatically invoked when printing the next label. Use Feed to Print Head (Short Form Feed) to
optimize print speed and to eliminate the reverse feeding when printing multiple labels.

© 2021 Sanford, L.P. 8
Short Form Feed Command (<esc> G)
This command feeds the next label into print position (die-cut labels). The most recently printed label
might still be partially inside the printer and cannot be torn off or cut. This command is meant to be
used between labels on a multiple label print job.
Use this command when printing multiple labels. The normal Form Feed command also works for this
purpose. However, using the Short Form Feed command optimizes the printer and minimizes print time
by eliminating the need to reverse feed after advancing the top-of-form mark to the tear bar, as the
normal Form Feed command does. The Short Form Feed command advances the printed label just far
enough to place the next label in position for printing. Because of the mechanics of the printer, the
preceding label will still be partially within the label exit slot. For a label to be in tear-off position, you
must use the normal Form Feed command (<esc> E).
Print Status Response
The LabelWriter 550 series responds to status request with 32 bytes dedicated to reporting its current
state.
The host requests the status from the printer by issuing an <ESC A> command (See the “Printer
Command” section later in the document for more details).
Self-Test Capability
The printers include a self-test capability in the form of canned print patterns. To activate the self-test,
press the form-feed button and power button together and hold it down for approximately 10 seconds.
The self-test will start printing a repeating series of test patterns. To stop the self-test, press the form-
feed button a second time.
Print Mode
The LabelWriter 550 series features the following print modes:
•Text
•Barcode and Graphics
The LabelWriter 550 and LabelWriter 550 Turbo has the additional print mode:
•High Speed ***NOTE: Not all label rolls have the high-speed feature***

N/A
For better accuracy of dot placement and sizing, the LabelWriter 550 series printers incorporate a
feature which allows the host computer to specify a 300 x 300 dpi Barcode and Graphics print mode. In
Barcode and Graphics mode, the print quality is improved by a reduction in print speed which provides
smooth and even printing, resulting in greater regularity of dot darkness and size. This mode may
improve print quality of smaller barcodes and some graphic images. This creates more precise dots for
better image quality.

Low Power Mode
The LabelWriter 550 series includes an automatic power saving feature. After 30 seconds of inactivity
the printer will shut down its unused internal peripherals and dim its LEDs. Pressing the power button
while the printer is in this state will cause it to resume normal operation rather than feeding a label. If
print data is sent to the printer while it is in Low Power mode it will automatically resume full operation.
Power Requirements
The LabelWriter 550 series printers are normally supplied with an external, universal (100 – 240 VAC) AC
power adapter. For OEM applications, a DC voltage can also be supplied to the main printed circuit
board (PCB) of the printer using the JP2 connector.
Note: The printers have been tested and certified for EMC and safety requirements using the supplied
AC adapter. Supplying a non-DYMO power source may change the EMC and safety certifications.
Input power is variable based on the amount of information printed and the duty cycle of the label
printing.
The printer driver (print commands from the host computer) controls some printing parameters and will
change maximum power usage.

USB Printer Interface
The LabelWriter 550 series printers all communicate with the host computer using a full-speed USB 2.0
interface. This interface also operates with USB Version 1.1 or later. The printers implement the
standard USB Printer Class Device interface for communications (see
http://www.usb.org/developers/devclass/).

© 2021 Sanford, L.P. 10
While it is not the purpose of this section to define how to write a USB driver for a printer device, this
section provides some product specific information that is required for any USB device.
Each USB device provides plug-and-play information when it is connected to a host computer. This
information includes a manufacturer specific, or Vendor, ID (VID) and a product specific ID (PID). These
identifiers, when combined with the class type provided during USB enumeration, are sufficient to
identify the driver to load.
USB Vendor ID
The USB Vendor ID (VID) assigned to DYMO by the USB Implementers Forum is 0x0922h (2338 Decimal).
USB Product IDs
Each printer has a unique Product ID, as shown in the table below.

LAN Printer Interface
The LabelWriter 550 Turbo and LabelWriter 5XL printers are also able to communicate with the host
computer using 10M/100M Ethernet LAN connection.
The printer will auto-connect upon ethernet cable plugin into the RJ45 connector.
IP Address
IPv4 protocol is supported.
By default, IP address of the LabelWriter 550 Turbo and LabelWriter 5XL printers will be obtained by
DHCP. Communication will be enabled upon successful assignment of IP address.
mDNS
The mDNS protocol is used to discover printer on the network and conforms with mDNS protocol (RFC
6762/6763) specifications. The port used for this service is 5353.
Below are the mDNS strings used for printers with a LAN interface:
