Abstract: A grayscale printing control method, a device thereof and a storage medium are provided. The method comprises: determining the grayscale level of image data of each point in each point line and converting the same into multi-bit binary data; forming a data set using the binary data of the same bit of all the points in a point line, thereby forming multiple data sets; each data set corresponding to a predetermined strobe time, and the print head heater corresponding to each point heating upon receiving predetermined data during the strobe time. The present invention can reduce the number of printing strobes and the times of data transmission while ensuring printing quality, thereby greatly improving printing speed.

Abstract: A printer control method includes the following steps: setting triggering conditions for executing functional items and for startup a configuration menu; executing a functional item if the key information had fulfilled the triggering condition for executing the functional item; and launching a configuration menu if the key information had fulfilled the triggering conditions for startup the configuration menu. By setting the triggering conditions for executing functional items and for startup a configuration menu, then determining whether the key information has fulfilled the triggering conditions for executing functional items and for startup a configuration menu, the printer directly executes the functional item as long as the key information has fulfilled the triggering condition for executing the functional item. When the printer is powered on, it skips the step of launching the configuration menu, operates conveniently and saves paper.

Abstract: The invention provides a print control method, comprising the steps of: detecting a state of a printing paper of a printing device; acquiring the length of a ticket to be printed when the printing device is in a paper near end state; judging whether the printing paper in the printing device is enough to print the ticket to be printed completely according to the length of the ticket to be printed; and printing the ticket to be printed under the condition of determining that the ticket to be printed can be completely printed. The invention also provides a print control device.

Abstract: An apparatus for processing a recording medium with embedded information comprises: a passage mechanism including a first passage, a loop passage and recording medium conveying rollers, wherein a first opening and a second opening of the loop passage are connected to the tail end of the first passage; a first guide mechanism configured to selectively communicate the first passage with the first opening or the second opening of the loop passage; and a processing device including a magnetic head and a print head which are arranged in the first passage, wherein the magnetic head is arranged at a side of a recording medium inlet/outlet port which is adjacent to a leading end of the first passage. A method for processing the recording medium with embedded information is also disclosed.

Abstract: The present invention discloses a ticket issuing method, comprising: step a: acquiring the image of a ticket paper for issuing a ticket, recognizing a ticket number from the image acquired and determining the validity of the ticket number recognized, to obtain a valid ticket number; step b: printing on the corresponding ticket paper the ticket issuing information containing the ticket number, when receiving a ticket issuing instruction. The present invention also discloses a ticket issuing device, comprising: an image acquisition unit (35), a printing unit (34) and a controller (31) for sending the image of the ticket paper acquired by the image acquisition unit or the ticket number recognized from the image of the ticket paper to a host computer (40) and controlling the printing unit (34) to print on the ticket paper according to the ticket issuing instruction and the ticket issuing information received.

Abstract: A printer includes a print head moving in printing and shifting regions, a carriage connecting the print head and the print head transport mechanism, and a ribbon cassette mounting mechanism that drives a multicolor ribbon cassette to swing. A ribbon cassette supporting mechanism in the shifting region correspondingly supports the ribbon cassette mounting mechanism to different levels to shift color of the ink ribbon while the ribbon cassette supporting mechanism rotates. A ribbon cassette shifting mechanism fixed on the carriage is used, in the shifting region, to lift the ribbon cassette mounting mechanism to a position disengaged from the ribbon cassette supporting mechanism and move the ribbon cassette supporting mechanism to rotate. A resetting mechanism fixed on the ribbon cassette supporting mechanism resets the ribbon cassette supporting mechanism when the ribbon cassette supporting mechanism no longer contacts the ribbon cassette mounting mechanism and the ribbon cassette shifting mechanism.
