Description
[technical field]
The utility model relates to a kind of printing adapter, is a kind of printing adapter that is used for off-line printing USB flash disk text specifically.
[background technology]
Existing text is printed the file printout function that needs to adopt PC equipment or embedded intelligent equipment usually.USB flash disk, full name " USB flash drive " is a kind of small-sized mobile storage disc, is used for picture, document etc., has only thumbnail, realizes portable mobile storage.If the documentation in the printing USB flash disk, need to start the file printout function of PC equipment or embedded intelligent equipment, like this, make the print file very inconvenience that becomes, and the computer power consumption big, take up room big.
[utility model content]
The utility model technical matters to be solved provides a kind of USB flash disk text printing adapter of being convenient to print the USB flash disk text.
Above-mentioned technical matters solves through following technical scheme:
A kind of USB flash disk text printing adapter is characterized in that: comprise main control module and receive USB flash disk file read module, user's load module, display module, the USB printing drive module of master control module controls; Said USB flash disk file read module reads outside USB flash disk file and is written to main control module; Said user's load module is that file processing provides the user to import; Said display module is realized the demonstration of literal and numeral; Said USB printing drive module receives print data and print command with the work of driving PRN device from main control module.
Further scheme is, Flash storer, SDRAM storer that said main control module adopts 32 high-performance processors and is connected with 32 high-performance processors.
Further scheme is, said display module adopts LCD.
Further scheme is, said USB flash disk file read module is used for the USB-A type socket that is connected with outside USB flash disk; Said USB printing drive module is used for the USB-A type plug that is connected with PRN device.
The utility model and the contrast of existing printing technique; Can improve the printing convenience of USB flash disk Chinese version file; If use the utility model to be connected to the PRN device USB interface, need only need USB flash disk be inserted into the USB-A type socket of the utility model by external PC equipment or smart machine; Need text of printing and the PRN device type that is connected through user's load module with the display module selection, can realize the printing of USB flash disk text.Therefore, the utlity model has the advantage of being convenient to print USB flash disk text, little and the low energy consumption of taking up space.
