NOTE The purpose of this manual is to serve as a reference to knowledgeable developers wishing to communicate directly with the LabelWriter printer without the use of printer drivers. Because the printer is a raster-based printer, this is not a simple task, and Sanford, L.P. reserves the right to limit development support for such implementations.

80° C. Printing resumes when the print head cools to 55° C. The DYMO LabelWriter Duo printer initially shipped with a 96-dot print head for the tape-printing mechanism. This has been replaced with a 128-dot print head.
<etb>, the data compression of the bit pattern. It is important to note that the n values which follow <syn> or <etb> characters are interpreted only as graphical data. This means that LabelWriter 400 Series Technical Reference Manual Page 8...
additional <syn>, <etb>, or <esc> characters will be treated as print line data, representing pixels to print, until the required number of bytes for the print line are received. The character received by the printer after the last data character should be an <esc> character, denoting a command sequence, or a <syn>...
“n” Lines command is executed only one time per instance and must be re-issued each time a skip is desired. The Status Byte The LabelWriter printer reports a status byte with several bits dedicated to reporting its current state. LabelWriter 400 Series Technical Reference Manual Page 10...
Barcode and Graphics Print Mode For better accuracy of dot placement and sizing, the LabelWriter 400 series printers incorporate a feature which allows the host computer to specify a slower, Barcode and Graphics print mode. This mode may improve print quality of smaller barcodes and some graphic images.
100 – 240 VAC, 50/60 Hz, 1.6 Amps Output voltage 24 VDC, 2.5Amps PCB Input Power All LabelWriter 400 series printers have an input voltage of 24 VDC, +/- 5%. Their power requirements are as follows. LabelWriter 400 and 400 Turbo Printers Input current (idle) 0.040 Amps...
USB Printer Interface The LabelWriter 400 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/).
Printer Commands All LabelWriter 400 series printers implement the same basic commands. The LabelWriter Twin Turbo printer implements one additional command, the Roll Selection command, and the LabelWriter Duo printer implements an additional, but similar, set of commands that are specific to printing on continuous-length tapes (see Appendix B).
<esc> q n Select Roll (Twin Turbo printer Only) 1B 71 ? n specifies the roll to print on, where: 30 (ASCII ‘0’) = Automatic selection 31 (ASCII ‘1’) = Left roll 32 (ASCII ‘2’) = Right roll LabelWriter 400 Series Technical Reference Manual Page 16...
<esc> c Set Print Density Light This command sets the strobe time of the printer to 75% of its standard duty cycle. LabelWriter 400 Series Technical Reference Manual Page 18...
Printing to the LabelWriter Duo Tape Printer Command Language The DYMO tape printers use a subset of the LabelWriter command language described earlier in this manual. Due to the nature of printing on tapes, some tape-specific commands have been added.

After performing these steps, whenever you print, you will be prompted to enter a file name and the output will be redirected to this file. Use the DYMO Label Software to print a variety of labels and examine the resulting files using a hex editor; use this manual to decrypt the data.
