A postage meter includes a printing device including a removable ink supply carried by the printing device. The printing device is movable on a carriage over an area in which printing of a postage indicia is to be effected and is movable to a location beyond that area for the purpose of replacement of the ink supply. Access to the printing device to replace the ink supply is by means of a hatch in a housing of the postage meter. The printing device can be moved and from the location only when the hatch is locked closed and the construction of the carriage and the mounting thereon of the printing device is such as to inhibit access to electrical connections between the printing device and the postage meter.
