Abstract: Described are a printer and a method of controlling it, wherein when an out-of-paper error occurs and printing stops, a control unit clears any data in a receive buffer, and reports the out-of-paper error and print stoppage to a host computer. When a clear buffer command is then received from the host computer, the control unit clears the receive buffer again.

Abstract: A printing apparatus including a plurality of ink cartridges each supplying ink; an image processor generates print data for each ink based on input print data; a buffer which stores the print data generated by the image processor for each ink; a print head for discharging the ink supplied from each ink cartridge from a nozzle group for each ink based on the print data for each ink stored in the buffer; and a supply line that supplies print data from the buffer to the print head.

Abstract: A recording control device controls a recording mechanism section which performs recording on a recording medium by a recording head. An image expansion section expands data input from the outside to create image data for recording. An image buffer memory temporarily stores the image data created by the image expansion section. A recording control section reads the image data stored in the image buffer memory, and controls the recording mechanism section to record the read image data on the recording medium by the recording head. The recording control section controls a recording speed of the recording mechanism section on the basis of a creation speed of the image data in the image expansion section.

Abstract: A hybrid processing system improves the reliability of multifeed detection even when plural different types of media are processed together without increasing the cost or size of the hybrid processing device due to increased performance, and without incurring a drop in throughput. In addition to image data captured from the processed media by an internal image reader, the hybrid processing device 1 also sends data for confirming multifeeding to the host computer 30. This multifeed confirmation data includes the result from a first multifeed detection process, the result from a second multifeed detection process, the paper length data detected by a paper length detection means 9, and the paper thickness data detected by a paper thickness detection means 65. The host computer 30 uses the image data and the multifeed confirmation data received from the hybrid processing device 1 to independently detect multifeeding, and thereby enables more reliable multifeed detection.

Abstract: When a label printer detects the paper width, the paper width detection operation scans the transportation path in the paper width direction by the paper width detector not once but twice, and conveys the recording medium transportation distance L, which is longer than the gap length of the gap between labels and is shorter than the label length of each label, between the first and second paper width detection operations. Of the two positions detected as the left edge of the recording medium in the first and second detection operations, the position that is farthest left is used. Likewise, of the two positions detected as the right edge of the recording medium in the first and second detection operations, the position that is farthest right is used.

Abstract: The first reading start point D of a front contact image sensor 21 and the second reading start point F of a back contact image sensor 22 are managed using a previously measured sensor-to-sensor distance L. As a result, even if there is a difference in the distance between the sensors, the first and second reading start points D and F will still be a first margin length L1 before the image reading positions A and B of the contact image sensors 21 and 22. Because the beginning of the front image information FD2 and the beginning of the back image information BD2 contained in the back-side image data BD1 in the images captured by the contact image sensors 21 and 22 match, the front image information FD2 can be extracted based on the coordinates of the back image information BD2 contained in the back-side image data BD1.

Abstract: A check processing device eliminates incorrect determinations by an insertion direction evaluation means that detects if the orientation of a conveyed check is correct or not based on the detection signal from a magnetic head. The check processing device 1 has an insertion direction evaluation means 76 that determines if the orientation of a check 6 is correct or not based on the detection signal from a magnetic head 23, a multifeed detector 62 and multifeed evaluation means 62a that detect multifeeding, an enable/disable control means 82 that enables or disables the insertion direction evaluation and multifeed detection operations of the insertion direction evaluation means 76 and multifeed evaluation means 62a, and a control means 83 that unconditionally enables multifeed detection when only the insertion direction evaluation is enabled.

Abstract: A hybrid processing device that continuously reads information from a plurality of process media can set the speed of the continuous reading process appropriately to the situation. The hybrid processing device 20 has a conveyance portion 2c, a reading control unit 28, and a discharge control unit 25 that runs a discharge process according to the result of the read process, and continuously reads a plurality of checks S according to instructions from a host computer 30. The reading control unit 28 runs a read process to read all read items when the reading accuracy priority mode is selected. When the reading speed priority mode is selected, the reading control unit 28 runs a read process to read only specific read items.

Abstract: A receiver configured to receive a first command that contains a predetermined code string and a second command that does not contain the predetermined code string from a host computer. A first command analyzer configured to analyze and process only the first command received by the receiver. A buffer configured to temporarily store at least the second command received by the receiver. A second command analyzer configured to analyze and process the second command stored by the buffer. A sound generator configured to generate a sound when the first command analyzer analyzes the first command and determines that the first command includes a sound generating command. The first command analyzer analyzes the first command before the buffer temporarily stores the second command.

Abstract: A print media processing apparatus increases printer throughput by starting printing after setting the conveyed print medium to the printing start position, and a transportation control unit controls how far the print medium is advanced according to the length of text to be printed on the print medium. The transportation control unit advances the paper to the position where printing text of a specified length to the printing area of the paper begins.

Abstract: Described are a printer and a method of controlling it, in which discarding received data and clearing data from a receive buffer is started when an off-line error occurs and the printer goes off-line. When the printer returns on-line, a control unit causes a data receiving unit to stop discarding said received data and causes sending a clear response as an on-line status report telling the host computer that the printer is returning on-line.
