Abstract: A scanning-printing integrated apparatus comprises a scanning passage (1), a printing passage (3) communicated with the scanning passage (1), a transitional passage (2) providing printing medium to the printing passage (3), a first driving mechanism for driving the paper conveying roller (12) of the scanning passage (1) and the paper conveying roller (312) of the printing passage (3), and a second driving mechanism for driving the paper conveying roller (21) of the transitional passage (2) and the paper conveying roller (312) of the printing passage (3). The two ends of the paper conveying roller (312) of the printing passage (3) are respectively transmission-connected to the first driving mechanism and the second driving mechanism via one-way bearings (71, 72).

Abstract: A printing control method, printer and printing system are provided. The printing control method comprises: receiving the ticket data to be printed; printing the ticket data; judging whether the printed ticket data is complete; and performing predetermined process according to the judgment result. The invention can conveniently and accurately judge whether a ticket is completely printed.

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: 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 method and device for controlling watermark printing are provided. The method comprises: receiving original printing information sent from a host; processing preset original watermark data based on a watermark control instruction to obtain application watermark data; composing the application watermark data and the original printing information to obtain composed data; and printing the composed data.

Abstract: An apparatus for detecting and processing identification features by using a detecting device in a cash desk, a microprocessor having a memory is assigned to the apparatus, characterized in that the identification features detected locally can be linked with the features stored centrally and the local function can be locked and released by an interlocking circuit.

Abstract: A service application method and system, and a service application control agent (SACA) for reducing the delay of service application are provided. The method includes the following steps. An SACA receives service application information sent from a customer premises equipment (CPE). The SACA queries for Quality of Service (QoS) parameters corresponding to the service according to the service application information. Resource authorization and reservation request information containing the QoS parameters is sent to a resource and admission control unit. The resource and admission control unit verifies the request information to be authorized and admitted, and delivers a control strategy to a transport unit after the verification is passed. A service application system and an SACA are also provided correspondingly.

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.
