While a specific application is running, a printer driver enables printing other data that is not data from the specific application. A dedicated driver (printer driver) that runs on a POS terminal occupies a communication port when receipt data is supplied from a POS application. The dedicated driver also sends print data generated based on the receipt data through the communication port to a POS printer. After continuing for a previously set time, the dedicated driver releases the communication port.

A conversion area in a storage of a printer is determined to accommodate slips of different sizes. Slips are conveyed along a path that is guided on one side and open on the other. A detector detects the length of the slip in the conveyance direction. Dimensions of the conversion area are determined based on the detected length of the slip, and a recording range of a recording head is also determined. Font data is read from memory based on font code that is received from a control device and written in the conversion area per line unit in the order in which the font code is received and in a direction corresponding to toward the open side of the conveyance path and away from the guided side of the conveyance path. The recording head is controlled to record the font data in the conversion area on the slip.

A recording device has a recording unit that records on a recording medium, a transportation unit that conveys and discharges from an discharge opening the recording medium recorded by the recording unit, a cutting unit that cuts the recording medium recorded by the recording unit at a predetermined position on the transportation path of the transportation unit, and a control unit that causes a ticket to be output by causing the recording unit to record on the recording medium while causing the transportation unit to convey the recording medium only a specified ticket length and causing the cutting unit to cut. When a next ticket is not output after a ticket is output, the control unit causes the output ticket to be recorded and conveyed the specified ticket length, advanced a preset additional transportation distance, and then cut by the cutting unit.

A controller and a control method for a controller can simplify application development and can improve the performance of device control processes. When a request is received from an applicationand the received process request is an initialization request, whether or not the received request is the first initialization request received after the applicationstarted running is determined. If the received initialization request is the first initialization request, the request is passed to the device driverand initialization settings information describing the configuration of the device driverafter the initialization process ends is stored. If an error has occurred in the device driverwhen the device driverstatus is detected, an error handling process is executed according to the device driverstate. When the device driverhas recovered, a request for setting the device driverstate to the state based on the initialization settings information is asserted.

A device control system, a device control method, and a device control program for rendering a trace function as a function added to a service object that provides the software application with an interface to a particular device based on the Microsoft .NET Framework. The device control system has a service object, a service object for tracing, and renders a trace function in a service object that provides a device interface to a software application based on the .NET Framework. The trace function can be rendered in the service object based on whether the trace function is disabled or enabled without modifying the software application.

An image correction apparatus and method enable correcting an image so that the image is always discernible and at least text can be read regardless of user settings. A correction range that increases the gray level and a correction range that decreases the gray level are calculated for each image to calculate the correction range suitable for the particular image.

A color reduction processing apparatus and method that is simple to configure and adjust produces two-color print image data reflecting the impression of the original full-color image. Each pixel in a full-color image is converted to binarized principal and secondary color print data by principal and secondary color processors respectively using respective threshold value matrices. The threshold values of these matrices, which are calculated from a reference threshold value matrix stored in memory, can be adjusted, via adjustment values, to control the overall density of the principal and secondary colors. The adjustment values can be set in a matrix configuration unit. The binarized principal and secondary color print data can also be further corrected by correction and/or filtering operations performed by a correction processor.

A simplified control system provides a uniform interface to a Java-based POS application. A new interface defining a method SetEntry for passing an entry point to a database to a device service object is created in the device service object which loads this interface as a rule. This allows greater freedom designing the device service object and makes it possible to write better service objects. Device service objects for other manufacturers and other types of devices can also be loaded by a shared factory class, and a simpler JavaPOS system can be provided at low cost.
