Dymo Labelwriter 550 Series Technical Reference Manual

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.
