20090091592Method of Inkjet Printing for Use in Point-Of-Sale Systems - This invention relates to a method of inkjet printing, in particular for use in POS systems. In particular the printing method according to the invention is of the thermal type. In order to obtain high speed printing, for example of 15-20 lines per second when printing text on a paper medium 60-80 mm wide (for example receipts), the drops of ink ejected during the printing operation advantageously have a relatively large volume, i.e. not less than approximately 100 picolitres (pl) and preferably between 100 and 200 pl. The ink used for applications in POS systems must quickly penetrate an extensive range of paper media. This requirement is satisfied by using an ink having a surface tension of not more than approximately 35 dyne/cm (mN/m). Problems of stagnation and dripping of the ink caused by the printing conditions are overcome through the use of a nozzle plate coated with a wetting-resistant layer of silicon carbide.

20120086747INK-JET RECORDING APPARATUS - There is provided an ink jet recording apparatus including an ink jet head; a scanning mechanism for scanning the ink-jet head; a transport mechanism including nip sections for nipping a recording medium; and a controller including a pattern forming mechanism, which controls the ink jet head to form a pattern including a mark for detecting a deviation between a landing position in a forward scanning and a landing position in a backward scanning; wherein the pattern forming mechanism controls the ink jet head to form a part of the mark on the recording medium in one of an area which overlaps in the transport direction with one of the nip sections and areas which are placed at outside positions of the nip sections nipping the recording medium at outermost positions in the scanning direction.04-12-2012
20130208037PRINT ELEMENT SUBSTRATE, PRINTHEAD, AND PRINTING APPARATUS - This invention provides a print element substrate having a plurality of printing elements. The print element substrate includes a detection circuit configured to detect substrate information of the print element substrate, a shift register configured to serially input print signals for performing driving control of the printing elements, serial-parallel convert the print signals, and parallelly output the print signals, a latch circuit configured to latch the print signals parallelly output from the shift register, and a driving circuit configured to drive the plurality of printing elements based on the print signals latched by the latch circuit. Detection signals based on the substrate information are parallelly input from the detection circuit to the shift register until serial input of next print signals starts after parallelly outputting the print signals from the shift register to the latch circuit.08-15-2013
