A printing device includes: a printing unit performing printing; and a control unit that, when accepting a character code associated with a plurality of font designs, causes the printing unit to print a character indicated by the character code, based on a priority level allocated to each of the plurality of font designs. The control unit changes the priority level of the plurality of font designs in response to a first command that is accepted. The first command is a command indicating the priority level of the font design that is a part of the plurality of font designs.

Printing device and control method for printing device

A printing device includes a printing unit, a buffer, and a control unit. The control unit reads out data from the buffer as target data. When the read-out target data is a character code, the control unit determines whether the target data is a character code associated with a plurality of character forms or not. When the target data is the character code associated with the plurality of character forms, the control unit prefetches data stored in the buffer after the target data, as prefetched data, before printing the target data, and determines whether the prefetched data is a predetermined code or not. When the prefetched data is the predetermined code, the control unit selects a character form indicated by the predetermined code as a target character form and causes the printing unit to print a character represented by the target data, in the selected target character form.

A printer includes: a storage region which stores a plurality of setting value groups in association with character strings, each of the plurality of setting value groups including one or more setting values for one or more setting items; and a processor. When the processor acquires a first command including one character string and instructing setting of an initial value of a setting item, the processor refers to the storage region to set, as an initial value, the setting value for the one or more setting items included in the setting value group associated with a character string corresponding to the one character string. When the processor acquires a second command instructing execution of a process relating to one setting item of the one or more setting items, the processor executes the process instructed by the second command by using the initial value thus set.

Control method of printer and printer

A composite processing device includes a check printing mechanism and a roll printing mechanism and executes printing using selected one of the printing mechanisms by a command. The composite processing device includes a sensor that detects whether the check printing mechanism and the roll printing mechanism are in a enabled state or a disabled state, and a processor causes a display to display check printing mechanism state information and roll printing mechanism state information based on results of the detection by the sensor. When the check printing mechanism is selected and is in the enabled state, the processor causes the display to display the check printing mechanism state information and the roll printing mechanism state information. When the check printing mechanism is selected and is in the disabled state, the processor causes the display to display information on the disabled state of the check printing mechanism.

Printer and method for controlling printer

A printing device is configured to be used simultaneously with other printing devices and includes: a print unit configured to print by ejecting ink from nozzles; a timekeeping unit configured to keep time; a storage configured to store a reference period for executing a nozzle maintenance operation, the reference period being initially set at an initial reference period; and a maintenance processor configured to: execute a nozzle maintenance operation each time the reference period passes based on the time kept by the timekeeping unit, change the reference period stored in the storage from the initial reference period to a changed reference period such that a timing of the nozzle maintenance operation differs from a timing of the nozzle maintenance operation of at least one of the other printing devices, and execute the nozzle maintenance operation after the changed reference period passes.

Printer, control method of a printer, control device, and maintenance system

A host control unit (processor) of a host which can be connected to a printer transmits a setting value requesting command which requests a response of a new function setting value, and a status requesting command which requests a response of a status value, thereafter, to the printer, and determines that the printer corresponds to the setting value requesting command, in a case in which the new function setting value using the setting value requesting command is received earlier than the status value using the status requesting command.

A printer driver enables appropriately executing real-time commands without causing operating errors even when print data is compressed for transmission to a printer. A driver causing a host computer that connects to a printer to execute a process, including causing the host computer to generate first commands executed by the printer in the order received, and second commands executed with priority over the first commands; generate print data including the first commands and send the print data to the printer; and execute a compression process converting data of the first commands contained in the print data to compressed data not containing a data train identical to a second command when generating the print data.

Host computer, control method of a host computer, and medium

Whether received data is the header of a print image command is determined in a receive interrupt process. If the received data is the header of a print image command, data transmission is paused. Whether the received data is a header of a print image command that can be transferred by DMA is then determined in a command task. If the received data is a header of a print image command that can be transferred by DMA, a DMA transfer mode is entered and the data transmission pause is cancelled, and the received data is transferred in the DMA transfer mode to a print bufferby DMA.

Printer and control method of a printer

Queries from a control device are answered based on the data actually used. When a control command is received from a host computer, the recording control unit of a printer changes a value related to the recordable area stored in a temporary storage area according to the content of the control command, uses the new value to record in the recordable area, and returns the new value when queried by the host computer about the setting for which the value was changed.
