A liquid discharging apparatus includes a print head that has a driving element and discharges a liquid, a drive signal generation circuit that generates the drive signal based on a drive signal generation control signal for controlling generation of the drive signal, and a drive circuit substrate on which the drive signal generation circuit is provided. The drive circuit substrate has an input connector that inputs the drive signal generation control signal into the drive circuit substrate and an output connector that outputs the drive signal from the drive circuit substrate. A distance between the input connector and the output connector is shorter than a distance between the drive signal generation circuit and the input connector. The distance between the input connector and the output connector is shorter than a distance between the drive signal generation circuit and the output connector.

Liquid discharging apparatus and circuit substrate

An information management device that manages the processing result of a print job processed by a print device through a network includes an information acquisition unit, an information output unit, a time setting unit, and a polling unit that performs an acquisition polling process in which the information acquisition unit acquires information on the print job that has been completed from the print device at a time when the information acquisition unit acquires the information on the print completion from the print device before the set waiting time elapses after the information output unit outputs the print job to the print device, and performs a checking polling process in which the information acquisition unit checks the print device for completion information at a time when the set waiting time elapses in a state that the information acquisition unit does not acquire the completion information from the print device.

Information management device, method of managing information, and program

A technique for distributed printing that ensures favorable operability within a sufficiently short time. The procedure first generates intermediate print data and executes the parallel rendering process by time sharing to sequentially convert page data on the first page of the intermediate print data into data adequate for the printers. Transmission of final print data converted for the first printer is carried out in parallel with the rendering process for the second printer. In a similar manner, transmission of converted final print data to the second printer and third printers is carried out in parallel with the rendering process for the next printer. The parallel rendering process sequentially converts page data on the second page of the intermediate print data into data adequate for the printers. Subsequently, the parallel rendering process sequentially converts page data on the third page of the intermediate print data into data adequate for the printers.

Control of distributed printing using data output control module

A technique for carrying out distributed printing from a general-purpose application program. An application program generates print data and issues a print command. A virtual printer driver receives the print command and returns performance information with regard to performances of a virtual printer to the application program. The application program converts print data into data suitable for the virtual printer based on the performance information and transmits the converted print data to the virtual printer driver. The virtual printer driver stores the input print data in the form of an intermediate print file into an HDD. A distributed printing utility reads the intermediate print file, allocates intermediate print data in the intermediate print file to respective printers according to a distributed form set in a dialog box, and outputs the print data in a distributive manner to real printer drivers provided for the respective printers based on the allocation.
