A3: virtual parallel port controller end of scan and jaws equipment, the virtual parallel port of establishment and corresponding apparatus node;
A4: open the end-to-end parallel port mapping of terminal to virtual desktop, user installation device drives in the virtual desktop, and be tied to the corresponding virtual parallel port, accomplish the mapping of end-to-end parallel port equipment I/O service.
Preferably, also comprise after the steps d: the user finishes the virtual desktop session and breaks off virtual desktop, and virtual parallel port controller discharges virtual parallel port and sweep equipment node, finishes the mapping of parallel port.
A kind of parallel port Redirectional system comprises: terminal, network router/hub and virtual desktop, terminal are set up data communication through network router/hub and virtual desktop and are connected;
The terminal comprises the terminal parallel port controller, is used to scan, discern and with the parallel port on the mode access terminal of file, accomplishes transmission, reception and the processing of control information and data message;
Virtual desktop comprises virtual parallel port controller, is used for creating virtual parallel port and corresponding apparatus node, sets up the parallel port mapping of terminal to virtual desktop; Intercepting application program and user to and the I/O of jaws equipment request and operation, and be redirected to terminal processes, the result that the terminal is returned analyzes and handles.
Preferably, also comprise gateway server, be used to realize data forwarding, the wide area network access operation is provided.
Preferably, also comprise configuration server, be used to manage concentratedly the user and dispose list, strengthen control and management parallel port mapping on the terminal.
The present invention compared with prior art has the following advantages:
A, the experience of the equipment on the conventional table is provided
In virtual desktop, remote desktop, create virtual parallel port and device node, transparent equipment experience fully be provided, the user can not feel with conventional table on difference.
B, enhancement apparatus compatibility and the dirigibility of using
Because the existence of virtual parallel port; Make and the driver of jaws equipment can be installed in terminal or any end of virtual desktop end, strengthened dirigibility, and this makes when driver not under the support terminal platform situation; Still have other choice, just strengthened the compatibility of equipment virtually.
The centralized management mechanism of c, adding port mapping
Use configuration server to come trustship to be directed against the mapping configuration of user parallel port, make convenient management, quick.

Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also shown in Figure 1; Parallel port Redirectional system theory diagram of the present invention; Comprise: terminal, network router/hub, gateway server, virtual desktop and configuration server; The terminal is set up data communication through network router/hub through gateway server and virtual desktop and is connected, and virtual desktop is set up data interaction through configuration server through network router/hub and terminal.
The terminal comprises the terminal parallel port controller, is used to scan, discern and with the parallel port on the mode access terminal of file, accomplishes transmission, reception and the processing of control information and data message.
Virtual desktop comprises application program, user and virtual parallel port controller, and the virtual desktop end is created virtual parallel port and corresponding apparatus node through virtual parallel port controller, sets up the parallel port mapping of terminal to virtual desktop; Intercepting application program and user to and the I/O of jaws equipment request and operation, and be redirected to terminal processes, the result that the terminal is returned analyzes and handles.
Gateway server is used to realize data forwarding, and the wide area network access capability is provided, and breaks through the LAN restriction.
Configuration server is used to manage concentratedly the user and disposes list, strengthens control and management to parallel port mapping on the terminal.
See also shown in Figure 2ly, parallel port reorientation method process flow diagram of the present invention comprises:
Step 201: start virtual parallel port controller at the virtual desktop end, be used to create virtual parallel port and corresponding apparatus node, develop and manage parallel port and shine upon end to end;
Step 202: start the terminal parallel port controller on the terminal, equipment I/O request that be redirected request such as the TCP that responds virtual parallel port controller and identification and virtual parallel port and operating;
Step 203: the terminal parallel port is redirected initialization operation, and is concrete, consults shown in Figure 3ly, comprising:
Step 301: the user opens the virtual desktop session and lands virtual desktop;
Step 302: the terminal parallel port controller reads in user's configuration and switching and jaws equipment to mapped mode;
Step 303: virtual parallel port controller end of scan and jaws equipment, the virtual parallel port of establishment and corresponding apparatus node;
