Dymo LabelWriter 450 Series Printers Technical Reference Manual
Thursday, 29 October 2015 | Tech Support
The LabelWriter 450 series printers (LabelWriter 450, 450 Turbo, 450 Twin Turbo, and 450 Duo) are high-performance, low-cost printers used for printing mailing labels, postage, file folder labels, bar code labels, and more. The printers have a 57 mm wide, 300-dpi print head and a 63 mm wide paper path. The LabelWriter Twin Turbo printer has two side-by-side label printing mechanisms in a single printer. The LabelWriter Duo printer has a label printing mechanism as well as a tape-printing mechanism that can print continuous-length labels in several different widths (6 mm, 9 mm, 12 mm, 19 mm, or 24 mm), using a 128-dot, 180-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 and either 300 or 600 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 450 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... [more]
