By properly selecting the first or second mode, an image pattern can be displayed or printed by dots at a desired quality and a desired speed on the basis of the vector font.

Abstract: The present invention relates to a power supply apparatus and provides a power supply apparatus capable of properly performing the protective operation at the completion of use of the instrument connected through the power supply line, when and after suspension of supplement from the side of the power supply apparatus. In response to the on/off operation of a switch 106 which is responsive to the closing/opening movement of the top cover member of the instrument for which the electric power is supplied, a MPU 110 generates an instruction for the instrument to move a state in which the instrument has turned to no-use condition and to be suspended to receive the power supply, and, based on the instruction, by means of a timer 107, after a predetermined period of time is measured, the supplement of the power supply is suspended.

Abstract: A thermal head controller includes a central processing unit (CPU), a storage unit, an arithmetic unit, a controller, and a thermal head. The CPU reads print data stored in the storage unit. The storage unit holds print data to be printed on a stamp print face, which are transferred from a host computer. The CPU transfers the read data to the arithmetic unit, and causes the arithmetic unit to perform print-pattern processing. The arithmetic unit stores pattern data in its shift register before processing the stored pattern data. The print-pattern processing is performed so as to prevent fine print from being erased due to the deformation of the stamp print face caused by heat conduction in polyethylene foam sheet when the stamp print face is formed. The CPU uses the controller to control the thermal energy of dots positioned on the border between print dots and non-print dots on the thermal head.

Abstract: A process corrects geometric errors in the transfer of information without mechanical intervention on the printing form, to compensate for the errors that occur and thus attain optimized print quality prior to imaging. The corrections are visually indiscernible, so that the artifacts created in the printed result by the corrections do not stand out in the image. A device-independent description of the page information to be printed is converted by a Raster Imaging Process into at least one device-dependent digital matrix. Each matrix with m rows and n columns contains the information for a certain color to be printed. After the individual matrices are produced, they are supplied to a matrix manipulation device, which subjects each matrix to a correction transformation using specific parameters. After the matrices are adjusted, they are supplied by a matrix transfer device to the digital imaging devices in the printing mechanisms.

Abstract: A host computer checks the frequency of type data such as a character code or a graphic pattern in print data. Type data with a high frequency is registered in a registered character management area in correspondence with a data ID and sent to a printer. The printer registers the received ID and data in a print data registration area. Thereafter, the host computer sends print data obtained upon replacement of the type data with the ID to the printer. The printer identifies an ID included in the print data, replaces the ID with the corresponding type data, and outputs the print data. With this processing, data with a high use frequency can be registered in the printer. Therefore, the data transfer amount from the host computer can be decreased, and the printing processing speed is increased. In addition, since the frequency is totalized, the memory in the printer can be effectively used.
