The printing unit is configured and arranged to execute printing based on a printing job. The paper feeding units are configured and arranged to supply paper to the printing unit. The storage unit is configured and arranged to correlate and store the paper feeding units and attributes of the paper held in the paper supply units. The control unit is configured to compare the attributes of the paper correlated with the paper feeding units with attributes of the paper specified with a printing job, and when there is no paper feeding unit for which the attributes correlated therewith is consistent with the attributes specified with the printing job, to display on a screen one of the paper feeding units in which to place the paper specified with the printing job.

Abstract: A printer includes a display unit, a printing unit and a printing control unit. The display unit is configured and arranged to display a paper registration screen for registering or confirming attributes of paper held in a paper feeding unit when display conditions have been satisfied. The printing unit is configured and arranged to execute printing. The printing control unit is configured to, when prescribed printing start conditions are satisfied during a period in which the paper registration screen is being displayed, control the printing unit to start printing job using the attributes registered before display of the paper registration screen as the attributes of the paper held in the paper feeding unit used with the printing job.

Abstract: Disclosed is a printer for performing a process on the basis of received print data, the process including feeding a print sheet for a page, printing on the fed sheet, and ejecting the printed sheet. The printer includes a controller that allows a sheet for a succeeding page to be ejected without being printed when allowing the sheet for the succeeding page to be fed before completion of the process on another sheet for a preceding page which is in progress and then recognizing the end of a print data block corresponding to the succeeding page.

Abstract: A printer 1 has an I/F section 31 for receiving data from a PC 2, a parameter-deriving section 35b for deriving a control constant on the basis of print setting information included in the received data, and a printer section 11 which performs printing operation on the basis of the print setting information, the control constant, and print data included in the received data.

Abstract: A file management apparatus includes the following elements: a first non-volatile storage medium that holds a metadata group including a plurality of pieces of metadata corresponding to a predetermined file type; a detector that detects a file of the predetermined file type; a metadata guide unit that introduces, as selection options, the plurality of pieces of metadata included in the metadata group corresponding to the predetermined file type of the detected file; a metadata selection unit that accepts selection of at least one piece of the introduced metadata; and a management data storage unit that stores the selected metadata in association with the detected file in a second non-volatile storage medium in which the detected file is stored.

Abstract: A printer for executing printing on the basis of tone data representing a tone of one of a plurality of colors of ink, includes an input unit that inputs first tone data for a color represented by N bits per pixel and second tone data for a color represented by M bits per pixel, M being larger than N; a storage unit that stores the tone data input by the input unit, the storage unit including a plurality of storage areas, each storage area having a capacity that can store a group of the first tone data within a predetermined print range, wherein multiple storage areas are used to store the second tone data; and a print unit that executes printing on the basis of the tone data stored in the storage unit, the print unit being capable of processing both the first tone data and the second tone data.

Abstract: The invention enables a print job cancel from a printer panel and an avoidance of a waste print. Also, the invention enables the waste print even when a network emergency occurs.

Abstract: A dot-matrix printer for printing on a printing medium comprises a dot-forming section for forming dots on the printing medium; and a referenced data section to be referred to during movement of the dot-forming section, a character string to be printed being indicated as data having a predetermined resolution. Where M dots per a unit length are formable on the printing medium in a moving direction of the dot-forming section, and upon printing an N-character string per the unit length, M and N both being natural numbers, if (M÷N) is not a natural number, the resolution in the moving direction is made to be L per N-character string, L being a least common multiple of M and N, and while the dot-forming section moves across the unit length, the dot-matrix printer prints while referring to the referenced data section for L times.

Abstract: When 31-dot space data specified in 120 dpi from a host is expanded in an image buffer 41 in 90 dpi, a command interpretation section of a printer finds 23/90 dots and an error 43 corresponding to 31/120 by calculation. Error correction information 44 indicating occurrence of the error 43 and the error amount is placed at a position in the image buffer 41 where print data cannot exist. An engine control section of the printer controls head drive in the amount to which the shift distance as long as error correction is added based on the error correction information 44.
