Abstract
A printer having a print head with a mounting portion, and a carriage with a supporting structure engaging the mounting portion of the print head to hold it in place on the carriage. The supporting structure includes a lateral positioning portion for positioning the print head laterally in a direction of movement of the carriage, a downward positioning portion for positioning the print head downwardly of the carriage, and a rear wall for receiving a force of reaction of the print head upon printing action on a platen. The printer comprises a biasing device for biasing the mounting portion of the print head downwardly and rearwardly against the downward positioning portion and rear wall of the supporting structure of the carriage, respectively. The carriage may include a serrated portion fixedly engaging a toothed belt for driving the carriage along the platen. In this instance, the printer includes a retainer member supported by the carriage to hold a linear section of the belt in engagement with the serrated portion, and hold a flexible cable connected to the print head in pressed contact with the linear section of the toothed belt.
