Be to the description only actually of at least one exemplary embodiment below it is illustrative, never as to the disclosure
And its application or any restrictions used.
Technology, method and apparatus known to person of ordinary skill in the relevant may be not discussed in detail, but suitable
In the case of, the technology, method and apparatus should be considered as authorizing part of specification.
It is shown here and discuss all examples in, any occurrence should be construed as merely illustratively, without
It is as limitation.Therefore, the other examples of exemplary embodiment can have different values.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
Fig. 1 shows the flow chart of some embodiments of the Method of printing of the disclosure.
As shown in Figure 1, this method comprises: step 110, adds virtual printer at the terminal；Step 120, it will virtually beat
The title of print machine issues cloud server；Step 130, printed driver is loaded by cloud server；Step 140, shape
At mimeograph documents and it is sent to practical printer.
In step 110, the title of the virtual printer added at the terminal is consistent with the title of practical printer.It is practical
Printer can be connect by network with terminal.
In the step 120, the mapping relations of virtual printer and virtual desktop are established, and the title of virtual printer is sent out
Give cloud server.In one embodiment, virtual desktop is connect with terminal by remote desktop display protocol, virtual desktop
It is connect by terminal with cloud server.Application program needed for user is run in virtual desktop, therefore virtual printer
As peripheral hardware, it is necessary to which establishing mapping relations with virtual desktop by terminal could interact with application program, for example, printing is empty
File in quasi- desktop.
In step 130, the driver corresponding with the title of virtual printer that load cloud server is sent.Example
Such as, since virtual printer is identical as practical printer name, cloud server can be in general print driver library
In find and the matched driver of practical printer and issue terminal.After terminal for accessing virtual desktop, table can be passed through
Face broker program will create printer according to the title of virtual printer, and load corresponding printed driver.
In step 140, mimeograph documents are formed in virtual desktop, mimeograph documents is handled according to driver, it will
Treated, and mimeograph documents export is printed to practical printer.
In one embodiment, the application program in virtual desktop generates mimeograph documents by common graphic interface, such as
Mimeograph documents can be EMF or XPS formatted file.Then mimeograph documents are sent to Print Spooler (printing background process
Service), decided whether that print driver is called to render mimeograph documents according to relevant configuration.
Data render can be carried out to mimeograph documents by driver and form print data (RAW data).RAW data are
The data that printer can be handled directly, such as PCL (Printer Command Language, printer control language) printing
The RAW data of machine are PCL order datas, and the RAW data of postscript printer are PostScript data.Finally by void
RAW data are transferred to terminal by quasi- printer, then are exported RAW data by the CUPS in terminal and beaten to practical printer
Print.Printer manufacturer can be overcome to support a variety of printers caused by deficiency to map Linux platform using CUPS output data
Technology and the problem of deposit.
Different printed drivers can be managed collectively by cloud server in this way.It need not be at the terminal
Different printed drivers is installed, it is only necessary to which printer name, which is mapped to virtual desktop, can load corresponding driving journey
Sequence.To simplify the installation procedure of printer under virtual desktop environment, improve work efficiency.
The technical solution of the disclosure is further described below by the connection schematic diagram in Fig. 2.
Fig. 2 shows the schematic diagrames of some embodiments of the Method of printing of the disclosure.
