Embodiment
Below in conjunction with accompanying drawing, be further described with other technical characterictic and advantage with regard to the utility model is above-mentioned.
The WIFI printer interface module that the utility model proposes is used for being connected to a printer, this printer can be directly via the utility model and desk-top computer, smart mobile phone, notebook etc. carry out radio communication, and need not to connect a large amount of cables.The utility model can be applicable to serial printer and parallel port printer simultaneously, and specific implementation sees for details following.
See also Fig. 1, the composition structural drawing when connecting serial printer for the utility model.As described in Figure 1, in this embodiment, the utility model comprises WIFI module 01, Logic control module 02 and external interface 03.Wherein WIFI module 01 is used for communicating with other terminals with WIFI function; Logic control module 02 is connected with WIFI module 01, is used for controlling the switching between WIFI printing type and conventional printing type; External interface 03 is used for connecting printer apparatus.
During work, the utility model can be selected the WIFI printing type, namely completes wireless printing by WIFI module and other devices communicatings; Also can select conventional cable connected mode to print.When the client does not want to use the WIFI function to carry out the serial printer printing, can cut off the serial ports connection of WIFI module 01 andlogic control module 02 by Logic control module 02, Logic control module 02 just will directly send on serial printer by WIFI printer interface module interface with the data that serial equipment sends and print; When the client wanted to use the WIFI function to carry out data-printing, Logic control module 02 can be with the cut-out that is connected with equipment with the serial printer of serial ports, opened being connected of WIFI module 01 and serial printer.The high-low level of two the I/O mouths of the switching of two kinds of connected modes by reading Logic control module 02 is selected to control.Simultaneously, control the LED lamp by two I/O mouths of Logic control module 02 and indicate various duties.For example, when the level of two I/O is high level, be connected with printer with the equipment of serial ports or parallel port, red LED lamp is bright, and green LED lamp is gone out; When the level of two I/O was low level, WIFI module 01 was connected with printer, and red LED lamp is gone out, and green LED lamp is bright.
Particularly, Logic control module 02 is chosen as programmable logic chip EPM3128, is used for processing WIFI module 01, with communicating by letter between the equipment of serial ports or parallel port and serial printer or parallel port printer.External interface 03 is 62 needle interfaces, is mainly used in selecting serial ports or Parallel Interface Communication with WIFI printer interface module and printer with the equipment connection of serial ports or parallel port by changing different cables.
