An image processing device combines an image of a medium exposed to visible light and an image of the medium exposed to ultraviolet light so that parts printed with UV ink can be easily identified. A control device (image processing device) has an image acquisition unit that drives an image sensor and acquires a first image by imaging the face of a check when exposed to a visible first light, and acquires a second image by imaging the face of the check when exposed to an ultraviolet second light; a reverse image generating unit that generates a reversed second image by reversing light and dark in the second image; and a second synthesizing unit that generates a second synthesized image by combining the first image and the reversed second image. Because the reversed second image that is the reverse of the second image becomes an image that is light overall, a drop in the luminance and a drop in the contrast of the first synthesized image can be suppressed, and parts printed with UV ink are easily discerned.

Image processing device, image processing method, and program

An electronic method for printing is disclosed, the method including receiving print data from a host computer, the print data including an indicator, wherein the print data does not include supplemental duplex or simplex printing settings, determining that the indicator is within the print data, analyzing the indicator to determine duplex or simplex printing, writing a first portion of the print data to a memory unit, writing a second portion of the print data to the memory unit, printing a first side of a paper according to the first portion of the print data, and printing a second side of the paper according to the second portion of the print data.

Printing device and control method for a printing device

A printing device and a control method for a printing device can freely change the distribution of print data to the front and back sides to achieve the desired duplex printing result when operating in a duplex printing page mode that converts the print data for one page after setting the data conversion area. A conversion step (step S) sets a break length hy that divides the data conversion areainto a first data storage areafor converting the first-side print data and a second data storage areafor converting the second-side print data in the page mode, and then converts the print data. A print step (step S) then simultaneously prints the first-side or front print data that is converted into the conversion area before the break, and the second-side or back print data that is converted into the conversion area after the break.

Printing device and control method for a printing device for distributing print data

A thermal printer and a control method for a thermal printer enable increasing throughput before a printing process starts by starting a duplex printing process without waiting to convert all print data into the front print buffer and back print buffer, enable executing a duplex printing process on a print medium without using a front print buffer and a separate back print buffer, and enable switching between simplex printing and duplex printing according to a specific command. The control method includes a step Sof receiving a printing process selection command specifying execution of a simplex printing process on a front sideof the print medium, a simplex printing process on a back sideof the print medium, a duplex printing process that prints on the front sideand the back side, and an identical front/back printing process that prints the same print data on the front sideand back side, a step Sof converting and buffering the print data, and a step Sof executing the printing process specified by the printing process selection command.

Printer and printer control method

A data processing apparatus comprising: flash ROM that can communicate with a CPU, the flash ROM comprises a boot sector that stores a boot selector program, a first boot sector and a second boot sector each storing a boot program that is selectively called by the boot selector program. The CPU executes the boot selector program to select the first boot sector or the second boot sector each storing a boot program to be executed. The CPU executes the selected boot program to verify a version code stored in a main sector and the selected boot sector. The CPU executes a main program when the version code in the main sector matches the version code in the selected boot sector.
