PRINTER, FOOD PRODUCT SCALE AND ASSOCIATED PRINTHEAD ASSEMBLY

原文（中文）

A printer includes a media path along which a media is movable, and a printhead assembly positioned along the media path at a first side of the media path, wherein the printhead assembly includes a printhead unit. A print roller is positioned along the media path at a second side of the media path such that media passes between the printhead assembly and the print roller. A biasing assembly is arranged for biasing the printhead unit toward the print roller, wherein the biasing assembly includes a biasing component that is movable in a direction across a width of the media path in order to laterally shift a zone of biasing pressure that urges the printhead unit toward the print roller as needed to accommodate media of different widths.
