Abstract: In a system of a data processing apparatus coupled to a printer, the apparatus sends a status information transmission request to the printer and, in response, receives status information from the printer. The status information includes ink storage identification information written in a memory contained in an ink storage, device identification information identifying the printer in which the ink storage is installed, and ink usage amount information for use by the printer in calculating a remaining ink amount.

Abstract: Control of a printer involves reading a cartridge identification number from a memory in a cartridge and storing such number, generating status information including such number and may further include a calculated ink usage amount, and sending the status information to a data processing apparatus, which may be a server. In some embodiments, the ink usage amount is calculated as a number of discharged ink shots. The server saves the status information. This or another upstream server can reliably determine the number of ink shots used by the printer only for printing from this status information. Such control is embodied in a program stored on a non-transitory controller-readable medium, which program is executed by a controller in the printer.

Abstract: A printing system enables easily recognizing the status of a printing process. The host computer 2 has a print job transmission unit that sends print jobs to a printer, a notification pattern setting unit that sets a notification pattern, and a notification control command transmission unit that sends a notification control command asynchronously to the print job transmission unit.

Abstract: A system in which a recording device is connected to another device can test the functionality of the recording device and test the functionality of the system including the recording device at the same time. A recording system 1 causes the printer 3 to execute a test relating to the functionality of the printer 3 in response to operation of a test switch 49, store the test switch 49 operation count, and return the stored test switch 49 operation count in response to a request from the host computer 2. The host computer 2 requests the printer 3 to send the test switch 49 operation count, and runs a test related to the recording system 1 based on the operation count returned by the printer 3 in response to the request.

Abstract: A printer 240 calculates the amount of ink used only for printing as a number of discharged ink shots, and sends this shot count with the printer serial number and ink cartridge ID to a server 220. The server 220 saves the shot count, printer serial number, ink cartridge ID, and an error correction code as status information. The server 220 or server upstream from the server 220 can reliably determine the number of ink shots used by the printer 240 only for printing from this status information.

Abstract: A printer and control method to control the operation of a printer to assure consistent print quality regardless of the paper length. A paper transportation control unit 101 and ASF control unit 103 drive a paper feed roller 78 and main paper transportation roller 23 for feeding a sheet S of print paper from the ASF 60 upon a paper transportation path and for advancing the sheet S of print paper on the paper transportation path in a first direction until the sheet S of print paper is discharged from the ASF 60, and then reversing the direction of travel of the sheet of paper S on the paper transportation path to convey the sheet S upon a reverse paper transportation path 80 disposed below the ASF 60 while positioning the sheet S to the print head 25a for printing by the print head 25a.

Abstract: A peripheral device and peripheral device control method assure the immediacy of status information while opening the greatest possible bandwidth when communicating status information using a USB interface enabling simultaneous access to a plurality of peripheral devices. A first transfer function enables sending status information to a peripheral device such as a printer using the USB bulk transfer type, and a second transfer function enables sending status information using the USB interrupt transfer type. Status information sent in response to a host request where the host can control the timing of status information transfers is sent by bulk transfer using the first transfer function, thereby assuring bandwidth for bulk transfers. Autonomous status information communicated at a timing unknown to the host is communicated by the second transfer function using the short transfer period interrupt transfer type, thereby assuring the immediate communication of the status information.
