A sheet processing apparatus comprises a sheet placing section in which recording media are stacked, a storage section configured to record a total amount of toner on the recording media stacked in the sheet placing section, and a control section configured to determine whether or not the recording media stacked in the sheet placing section is likely to stick when a new recording medium is stacked thereon, based on the total amount of toner on the recording media stacked in the sheet placing section.

Disclosed is a printing device including a main body part including a body part configured to provide an internal space in which recording paper for printing certain information thereon is transferred and an opening or closing part configured to control opening or closing of the internal space, a printing part configured to print the certain information on the recording paper transferred in the internal space, and a recording paper separation part located on a downstream side of the printing part and configured to cut or cut off and separate recording paper on which particular information is printed by the printing part from the other recording paper. Here, the main body part includes a protruding part configured to prevent an adhesive attached to the surface opposite the adhesive surface from being accumulated by decreasing a contact area with the surface opposite the adhesive surface.

A printer includes a printer body, a lid, a lock, a lock lever, and an open lever. The lid is attached to the printer body to be opened and closed. The lock locks a platen roller attached to one of the printer body and the lid. The lock lever unlocks the locked platen roller. The open lever is so provided on the lid as to slide. The open lever slides to press the lock lever to open the lid.

An illustrative dye sublimation apparatus may include a heating surface that may have multiple zones. Each zone may include a single individually controlled heater. A controller may control the heater to generate a range of heat and not merely turn the heater ON and OFF. Therefore, one or more controllers may individually regulate heat from corresponding heaters in the zones thereby maintaining a constant and nearly constant temperature throughout the bed of the dye sublimation apparatus in the heating surface. Furthermore, one or more controllers may maintain a first range of temperature during a first state of a dye sublimation process and a second range of temperature during a second stage of the dye sublimation process.
