Abstract:
1. A portable printer, comprising: a housing having a cavity defined therein which supports a roll of stock material for printing indicia thereon, the housing including a drive motor assembly configured to move the stock material through a paper path defined in the housing; a battery loadable within a battery compartment disposed in the cavity; a cover assembly pivotably supported on the housing and moveable from an open configuration for loading the roll of stock material to a closed configuration to enable printing; and a selectively adjustable media support assembly which supports the roll of stock material, the media support assembly including a paper tray being slideable within a media support tray from a first position for supporting a roll of stock material of a first size, to a second position for supporting a roll of stock material of a second size, the paper tray including a stanchion having an eccentric cam face configured to engage the media support tray and being rotatable about an axis parallel to a center axis of the roll of stock material from a first orientation which allows selective sliding adjustment of the paper tray wherein the eccentric cam face of the stanchion is disengaged from the media support tray, to a second orientation which prevents sliding adjustment of the paper tray wherein the eccentric cam face of the stanchion engages the media support tray.
