Abstract

The utility model relates to a printing adapter. The printing adapter comprises a main control module supporting file transfer protocol (FTP) server, a WiFi wireless network module and a printing drive module, wherein the WiFi wireless network module and the printing drive module are connected with the main control module. The WiFi wireless network module is used for other devices transfer printing data to the main control module through the FTP server. The main control module receives the printing data and outputs the printing data combining with a printing instruction to the printing drive module. The printing drive module receives the printing data and the printing instruction from the main control module so as to drive printing devices to work. Compared with existing printing technologies, the printing adapter enables an intelligent mobile terminal device having a WiFi function and supporting the FTP server to very conveniently perform file printing.

Description

Printing adapter

Technical field

The utility model relates to a kind of wireless printing adapter, is a kind of printing adapter based on the WiFi wireless network specifically.

Background technology

Along with popularizing of intelligent mobile terminal equipment, the enhancing of file processing function, increasing user directly processes file on intelligent mobile terminal equipment; Due to present many intelligent mobile terminal equipment such as smart mobile phone or panel computer etc., do not support the local printing function, print file can only download on computer, the printer that connects by computer prints.Like this, make print file become very inconvenient and consuming time.Based on above purpose, the inventor has designed the application's scheme.

The utility model content

Technical problem to be solved in the utility model is to provide the printing adapter that a kind of intelligent mobile terminal equipment of being convenient to have the WIFI function and supporting FTP to serve is realized file printout.

Above-mentioned technical matters solves by the following technical programs:

A kind of printing adapter is characterized in that, comprises that one supports the main control module of FTP service and WiFi wireless network module, the printing drive module that is connected with described main control module; Described WiFi wireless network module is used for realizing that other equipment pass through FTP service transmission print data to described main control module; After described main control module receives described print data and be defeated by described printing drive module in conjunction with print command; Described printing drive module receives print data and print command to drive printing device work from described main control module.

Further scheme is, described main control module adopts 32 Flash storer, SDRAM storeies that high-performance processor is connected with 32 high-performance processors, and 32 high-performance processors connect described WiFi wireless network module, described printing drive module.

Further scheme is, described printing drive module adopts for the USB-A type plug that is connected with printing device.

Further scheme is, described WiFi wireless network module adopts the communication module of IEEE802.11 WLAN standard, and is connected with antenna.

By such scheme as seen, after loading onto the utility model printing adapter on printer, intelligent mobile terminal equipment with WIFI function does not need to be equipped with printing function or print driver is installed, only need to upload print data by the FTP service of wireless network and be given to the utility model printing adapter, the utility model printing adapter is just automatically completed and is driven the printer print data.Therefore, the utility model and the contrast of existing printing technique make to have the WIFI function and support the intelligent mobile terminal equipment of FTP service to carry out easily file printout.

Embodiment

As shown in Figure 1, a kind of printing adapter that this embodiment provides comprises the main control module 1 of supporting the FTP service and WiFi wireless network module 2 and the printing drive module 3 that is connected with main control module 1; WiFi wireless network module 2 is used for realizing that other equipment pass through FPT service transmission print data to main control module 1; After main control module 1 receives print data and be defeated by printing drive module 3 in conjunction with print command; Printing drive module 3 receives print data and print command to drive printing device work from main control module 1.Wherein, main control module 1 adopts 32 Flash storer, SDRAM storeies that high-performance processor is connected with 32 high-performance processors; WiFi wireless network module 2 adopts the communication module of IEEE802.11 WLAN standard, and is connected with antenna 7; Printing drive module 3 adopts for the USB-A type plug that is connected with printing device.

the principle of work of above-mentioned printing adapter: main control module 1 provides FTP (file transfer protocol (FTP)) service, after intelligent mobile terminal equipment passes through its WiFi function and WiFi wireless network module 2 is connected, intelligent mobile terminal equipment is served to upload by FTP and is printed data on main control module 1, main control module 1 is issued printing drive module 3 with print data and in conjunction with print command, printing drive module 3 sends print command and drives the described print data of printing device printing, after described print data is printed and is finished, printing drive module 3 notice main control modules 1, the described print data of completing has been printed in main control module 1 deletion.

As shown in Figure 2, the hardware circuit part of the main control module 1 of above-mentioned printing adapter, WiFi wireless network module 2, printing drive module 3 mainly is arranged on a circuit board 5, and circuit board 5 couplings are arranged in shell 4; The USB-A type plug 6 of printing drive module 3 and the antenna 7 of WiFi wireless network module 2 are separately fixed on described shell 6; Power module 8 provides direct supply for circuit board 5.

As shown in Figure 3, the file printout service routine of above-mentioned printing adapter comprises that mainly WiFi wireless network linker 9, ftp file upload program 10, print manager 11, print driver 12; WiFi wireless network linker 9 is the wireless network Connection Service between intelligent mobile terminal equipment and printing adapter; Ftp file is uploaded program 10 and is served upload file to main control module 1 service for intelligent mobile terminal equipment by FTP; Print manager 11 after file being detected, sends print command to printing drive module 3 by detecting in real time main control module 1 File, and print data stream is sent to print driver 12, and the file that deletion has been uploaded after finishing; Print driver 12 obtains the print.er port state by USB, for the data communication between printing adapter and printer provides guarantee, is printed by the printing device execute file that connects at last.

As shown in Figure 4, the file printout data transfer process process flow diagram of above-mentioned printing adapter:

S1: intelligent mobile terminal equipment is enabled the WIFi function, and search WIFi wireless network;

S2: according to the WIFi wireless network that searches, select to connect WiFi wireless network module 2 specified wireless networks, and connect;

S3: open the FTP service on intelligent mobile terminal equipment, set up the FTP service and connect;
