Abstract:
A print system capable of exchanging data in the form of electronic mail between a plurality of computer systems using very low-cost communication via the Internet 28, rather than one-on-one communication. When the printer driver 30 of a personal computer 4 selects a personal computer 10 on another computer system as the destination for transmitting print data, the printer driver 30 and the print mail transmission utility 31a create print mail in which a mail header including print information is added to the print data for the contents of the mail, and the print mail is transmitted via the Internet 28 addressed to the personal computer 10. The print mail reception utility 31b of the personal computer 10 receives the print mail and prints the print mail on a printer 14 based on the print information included in the mail header.
Abstract:
When the received mail is determined to be print mail in S981 based on its mail header, the program first determines in S982 what page description language is used to describe the print data in the mail. In S983, the program selects a printer which is being presently set to interpret that page description language. Then, in S1040, print data in the print mail is printed using the printer thus selected in S983. If there exists no printer appropriately set to interpret that page description language, the program selects in S983 a printer provided with a function to interpret that page description language. The program then sets the function mode of the printer into a mode to interpret the page description language. Then, in S1040, print data in the print mail is printed using the thus selected and set printer. Thus, the print mail is printed by a printer which can appropriately interpret the processing format of the print data included in the received print mail. Hence, the print data will not be printed erroneously. The user on the receiving end can receive printed matter in the form desired by the user on the transmitting end.
Abstract:
An image forming apparatus is provided to smoothly form images corresponding to received image data even if the memory becomes full when collated printing is executed. If the memory never becomes full during collated printing, images for all of the pages are expanded to intermediate data, stored in a page memory, and complete collated printing is enabled. In the meantime, if the memory becomes full while the print data of part of a page is expanded to intermediate data and stored, the controller, controls so that the page memory can be written after collated printing is executed up to a page immediately before the partial page and the residual pages are printed in the form of collated printing. Therefore, even if the memory becomes full, printing can be executed in a form as close to collated printing as possible.
Abstract:
An information recording device can function as a facsimile, a copy machine and a printer. The device receives plural kinds of information to be recorded and judges the kind of the information thus received. The information received is recorded onto a paper. The device is provided with a plurality of paper trays, and a delivering unit delivers a recorded paper on which the information is recorded to one of the paper trays which is determined in accordance with the kind of the information to be recorded. Thereby, the recorded paper on which same kind of information is recorded is delivered to same one of the paper trays, and a user can easily discriminate the recorded papers of different information.
Abstract:
In a diamond cutting saw blade, a plurality of slits 1 are formed at regular intervals on the outer periphery of a disc-shaped iron substrate 2, and a plurality of segment chips 3 are fixed onto the outer periphery of the disc-shaped iron substrate 2. Two trapezoidal concave portions 4 which expand outwardly are formed on both sides of the outer periphery of each segment chip 3. Further, a trapezoidal concave portion 5 is formed at the intermediate position of the segment chip 3 on a joint surface of the iron plate 2 so as to expand toward the joint surface. At the corner where a bottom surface 4a and a tapered surface (side surface) 4b of the concave portion 4 formed on the outer periphery intersect, there is formed a curved surface 4c having a radius of 1.0 to 2.5 mm. Similarly, in a concave portion 5 formed in the inner periphery of the segment chip 3, there is formed a curved surface 5 c having a radius of 1.0 to 2.5 mm at the corner where a bottom surface 5a and a tapered surface (side surface) 5b intersect each other.
Abstract:
A perfecting printer for performing a double-face printing operation of printing images on obverse and reverse faces of at least one sheet on the basis of a series of print data input from an external device and a method for controlling the double-face printing operation of the printer. The perfecting printer includes a page memory having an empty area for storing a series of print data for the obverse and reverse faces of the sheet input from external device, and a control unit for judging as to whether the empty area is no longer available in the page memory while the series of print data are being stored into the page memory and forcibly printing print data for the obverse face of the sheet on the sheet when it is judged that the empty area is no longer available in the page memory and that only the print data for the obverse face of the sheet are completely stored in the page memory.
Abstract:
A isolation amplifier circuit comprises: an operation amplifier provided with a first and second input terminals, an output terminal, and a feedback resistor for connecting the output terminal and second input terminal; a first emitter follower, for inputting a signal, connected to the first input terminal; a second emitter follower connected between the output terminal and the feedback resistor; a third emitter follower connected between the second input terminal and a first ground impedance; and a fourth emitter follower connected between the first input terminal and a second ground impedance. In the isolation circuit, dynamic resistances of the first, second, third, and fourth emitter followers are made identical with one another.
Abstract:
A network system includes printers as terminals interconnected via a network. Each of the printers can obtain information on the others, and transmit the obtained information together with information on itself to a browser computer as a controller. Therefore, by obtaining the information only from one of the printers, the computer can obtain together with it the information on the others. In this system, it is possible to obtain the information on the printers efficiently without using a server computer.
Abstract:
An image forming apparatus includes: a printing unit that performs a printing operation; a printing possibility determination unit that determines whether printing is possible, at the time of starting the printing operation; a printing stop unit that stops the printing operation, when the printing possibility determination unit determines that printing is impossible; a notification unit that notifies an error, when the printing operation is stopped; a notification time counting unit that counts a period in which an error is notified; a notification release unit that releases error notification, when the period in which an error is notified by the notification unit is counted for a predetermined time; and a stopped state reset unit that returns a stopped state of the printing unit whose printing operation is stopped, to a standby state before the printing unit performs the printing operation, when notification of an error is released.
Abstract:
A laser beam printer 1 is connected to a host computer and receives job data 100 from the host computer. The job data 100 includes a transmission time information 103. If the laser beam printer 1 is provided with a clock IC 98, a CPU 91 of the laser beam printer 1 reads a current time from the clock IC 98 and set the current time as receiving time information. On the other hand, if the laser beam printer 1 is not provided with the clock IC 98, then the CPU 91 sets the transmission time information 103 included in the received job data 100 as the receiving time information.
