A control device of a printer can delete unnecessary data left in the printer when processing is interrupted without relying on user intervention. A control device of a printer that prints according to print data has a transmission monitor unit that sends the print data to the printer. Based on the status of a storage unit of the printer, the transmission monitor unit sends a command to delete identical data from the storage unit to the printer before sending the print data to the printer.

Printer control device, printing system, and control method that deletes unnecessary data due to interruption

An information processing device having plural control units appropriately executes an arbitration process when a control unit is hibernating (in power-saving mode) and transmits data correctly to an external device. The information processing device has a first CPU and a second CPU; a first memory embedded in a semiconductor chip including the first CPU and second CPU; and a second memory disposed externally to the semiconductor chip. The first CPU executes an arbitration process according to the type of event that occurred when the first CPU is in a first state, the second CPU and the second memory are in a second state different from the first state, and an event requiring sending data from the first memory to the second memory occurs.

Information processing device, printing device, and control method

A printing device runs a process that uses resources efficiently and is compatible with configurations having multiple reception units. The printerhas a first immediate execution command managerthat monitors if an immediate execution command was stored in a first receive buffer, and if an immediate execution command was stored, reads and runs the immediate execution command; and a second immediate execution command managerthat monitors if an immediate execution command was stored in a second receive buffer, and if an immediate execution command was stored, reads and runs the immediate execution command.

Printing device, control method of a printing device, and printing system

An electronic device is connectable to an external device. An interface substrate is detachably connected to a main substrate. A first interface is installed on the interface substrate, and the first interface is connectable to the external device. A second interface is installed on the main substrate, and the second interface is connectable to the external device. A selection unit selects one interface of the first interface on the interface substrate and the second interface on the main substrate. A communication unit communicates information with the external device through the interface selected by the selection unit. At least one of the first interface and the second interface is configured to detect a connection state to the external device. The selection unit selects an interface which is designated or preferentially selects an interface which detects a connection to the external device.

Electronic device and control method thereof

Managing commands that have not been executed is simplified while maintaining a state in which real-time commands can be executed. A printerhas a write control unitA that writes received commands to a receive buffer, a command execution unitB that executes the written commands, and a real-time command execution unitC that executes written commands that are real-time commands. The printerenters a full-buffer mode as needed by the capacity of available storage space in the receive buffer, and when in the full-buffer mode the write control unitA cyclically writes commands to an auxiliary space created in the receive buffer, and the real-time command execution unitC reads and executes real-time commands from the auxiliary space.

Electronic device, control method for an electronic device, and recording medium

Managing commands in a buffer is simplified while continuing to enable immediately executing real-time commands. A control unit of a printer sequentially writes commands received from a host computer to a first buffer and sequentially reads the commands. If the read command is a real-time command, the control unit executes the command. If the read command is a normal command, the control unit writes the command to a second buffer without executing the command from the first buffer. The control unit sequentially reads and executes normal commands written to the second buffer.

Recording device, recording device control method, and storage medium

A recording device is connectable to a host computer and performs recording on the basis of received data including commands, received from the host computer. A receiving buffer stores therein the received data received from the host computer. A command detection section reads the received data stored in the receiving buffer while scanning the receiving buffer with a first read pointer to detect the commands included in the received data. A command execution section processes the commands detected by the command detection section in a stored order of the commands in the receiving buffer. An immediate processing command detection section reads the received data stored in the receiving buffer while scanning the receiving buffer with a second read pointer which is provided separately from the first read pointer to detect an immediate processing command included in the received data. The command execution section preferentially processes the immediate processing command detected by the immediate processing command detection section regardless of the stored order of the commands in the receiving buffer.

A selection unit selects one interface of the first interface on the interface substrate and the second interface on the main substrate. A communication unit communicates information with the external device through the interface selected by the selection unit. The selection unit selects an interface which is pre-designated or preferentially selects an interface which first receives a signal from the external device, between the first interface and the second interface.

Electronic device, control method thereof and recording medium

In a label printer in which either a peeling mode or non-peeling mode can be selected as the label dispensing mode, labels are printed and thus wasted when the operator loads the label paper into a transportation path that does not match the desired dispensing mode. This problem is solved by a label printer enabling selecting as the printing configuration either a peeling configuration for peeling printed labels from the web of label paper, or a non-peeling configuration in which the printed labels are not separated from the web of the label paper. A printing configuration selection unitenables selecting which printing configuration to use. To operate in the non-peeling mode, the label paperis loaded into a first paper transportation path A. To operate in the peeling mode, the label paperis loaded to a second paper transportation path B. A cover unitcan be opened and closed to enable handling the label paper, and takes the label printer off-line when the cover unitis opened. A mode selection switchis accessible only when the cover unit is open and operating the mode selection switch causes the printing configuration selection unitto change the printing configuration.

Label printer with selectible dispensible modes for peeling and non-peeling modes

An output device can be quickly and easily set to the operating parameters required for a particular output process according to data received from a host device. The output device has RAM that temporarily stores the operating parameters, a memory initialization processor that initializes the volatile memory in response to a specific input, a controller that stores operating parameter values for controlling the output device into the RAM in response to one or more first commands from the host device. A second command from the host device causes a first operating parameter controller to save the operating parameters from RAM into a flash ROM. A second operating parameter controller responds to a third command from the host device by storing information into the flash ROM indicative of whether operating parameter data in the flash ROM should be automatically loaded after the memory initialization process. A third operating parameter controller is effective for restoring the operating parameters from flash ROM to RAM after the memory initialization process only when the information in the flash ROM indicates that operating parameter data stored in the flash ROM should be automatically loaded. A particular operating environment defined by the parameters stored in nonvolatile memory can therefore be quickly reset en masse.

Output device with adjustable operating parameter values via host commands

A printing apparatus includes a data receiver that receives command data from a host device and a memory that stores the command data received by the data receiver. A printer controller reads out the command data stored in the memory in a first-in-first-out order and controls the printing apparatus in accordance with the command data. A command detector is provided to detect predetermined command data within the command data received by the data receiver without storing the command data in the memory or while or before command data is stored in the memory. An off-line recovery controller enables the printing apparatus to recover from an off-line state in accordance with the predetermined command data detected by the command detector.

Printing apparatus and a control method therefor

An output device () can be quickly and easily set to the operating parameters required for a particular output process. The output device has RAM () that temporarily stores the control parameters, and flash ROM () that stores the same parameter values in a nonvolatile manner. Specific parameter values are stored in RAM () in response to a specific command from the host (). A customization command causes the output device () to save the operating parameters from RAM () into the flash ROM (). Another customization command causes the output device () to restore the parameters from flash ROM () to RAM (). A particular operating environment defined by the parameters stored in nonvolatile memory can therefore be quickly reset en masse.

Output device, method of controlling it, and storage medium

A printing apparatus comprises a real-time command detector connected to the data receiver without the memory therebetween to detect control commands. Status data is transmitted to a host device in response to a real-time command from the host device.

Printing apparatus with real-time status reporting to a host device

When a communications terminal has stopped operating because it is off-line, data received from a host is efficiently stored to a receive buffer so that receive buffer full states cannot easily occur. A data interpreter interprets the receive buffer content in the input order. An action buffer stores interpreted commands. A command execution controller executes commands in the action buffer in first-in first-out order. The data interpreter continues interpreting the received data even when operation of the command execution controller is stopped, and kills without storing to the action buffer any real-time commands detected by the data interpreter.

Terminal printing apparatus, method of processing received data therein, and computer program product for achieving the method

The present invention is directed to a printer with a cleaning function in which CPU monitors a detection switch, and performs cleaning and printing operations as required until the detection switch is pressed(step S ). When the detection switch is pressed (step S returns yes), the printer indicates a &ldquo;near end of ink&rdquo; notice using the display panel or by flashing an LED, for example. A near end of ink notice is also sent to the host computer (step S ). A remaining ink volume counter is then set to a specific value, which in this exemplary embodiment is 5 mg (step S ). When a print command is next received (step S returns yes), the ink consumed by the print operation is subtracted from the remaining ink volume, and the difference is stored as the new remaining ink volume (step S ). The CPU then waits for a cleaning command (step S ). When a cleaning command is received, the CPU calculates the ink volume required for the cleaning operation, that is, the above-noted cleaning volume (step S ). If the cleaning volume is greater than the remaining ink volume (step S returns no), the cleaning mechanism is not driven, the user is notified that ink tank replacement is required using an LED, display panel and/or notifying the host computer (step S ), and the printing process ends. If the cleaning volume is less than the remaining ink volume (step S returns yes), ink jet head cleaning is possible. The cleaning mechanism is therefore driven (step S ) to suction an ink volume determined by the selected cleaning method, and this cleaning process ends.
