A printing apparatus heats a print medium in which color development layers that develop colors in accordance with heating are stacked in correspondence with a plurality of color. The apparatus includes a drive unit configured to drive each of heating elements of a printhead using a first pulse for preheating a predetermined color development layer, and a second pulse applied after the first pulse to cause the predetermined color development layer to develop the color, and a pulse control unit configured to, when developing a specific color, perform a control in which a pulse width of the first pulse is increased and/or a control in which the number of times of application of the second pulse is increased such that another color development layer that is not used to reproduce the specific color does not develop the color.

An image-forming apparatus includes a condensation determiner that determines whether there is a possibility of condensation occurring inside the image-forming apparatus using condensation determination information including a measured apparatus temperature inside the apparatus, a preparation processor that performs a preparation process for executing a print function, and a preparation waiting time setter that sets a preparation waiting time indicating a period of time for performing the preparation process. When the image-forming apparatus is powered and it is determined that there is a possibility of condensation occurring inside the image-forming apparatus, a preparation waiting time is set using the condensation determination information and the preparation process is started. After counting of the preparation waiting time is started, it is determined that a periodically-measured fusing temperature reached a predetermined target temperature, and thereafter, the counted preparation waiting time elapsed, the preparation process is canceled.

At step S115, a printer control unit refers to a table using an average print duty as an input, and determines a saturation temperature and a drum preliminary heating temperature. In this example, since the saturation temperature and the preliminary heating temperature with respect to the print duty are stored as a table, the printer control unit refers to the table using the average print duty as the input, and determines the saturation temperature and the drum preliminary heating temperature. At step S120, the printer control unit investigates a current drum temperature based on a measurement result of a temperature sensor. Subsequently, at step S125, the drum is heated or cooled until it reaches, of the saturation temperature and the drum preliminary heating temperature, the temperature for which the difference with the current drum temperature is smaller.

A thermal printer includes a thermal head, a temperature sensor, and a controller. The thermal head includes heat generation elements configured to generate heat to perform printing. The temperature sensor is disposed in the thermal printer. The controller is configured to alternately turns on and off the heat generation elements during an idle state of the thermal printer for a number of cycles with a predetermined on-time period in each cycle. The controller determines the number of cycles and the predetermined on-time period based on temperature data obtained by the temperature sensor, such that heat energy generated by the heat generation elements during each of the cycles in the idle state is lower than heat energy generated by the heat generation elements during printing of one line.

In one example, a method for an inkjet web printer includes a print engine printing a first print job on a moving first web, a printer controller receiving a second print job, the printer controller determining that the second print job may be printed after the first print job on a second web automatically spliced to the moving first web, a web supply automatically splicing the second web to the moving first web, the printer controller reconfiguring the print engine from a first configuration for the first print job to a second configuration for the second print job without stopping the moving first web or the moving second web, and the print engine printing the second print job on the moving second web.
