Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Note that below in conjunction with attached drawing and specifically real
The aspects for applying example description is merely exemplary, and is understood not to carry out any restrictions to protection scope of the present invention.
Fig. 1 is to show conventional printer physical connection figure.As shown in Figure 1, print client 100 (such as PC people
Computer) pass through network connection to printer 200.Printing driving is installed, in print client 100 in print client 100
On when thering is target print content to need to print, target print Content Transformation can be identified at printer 200 with printer language
Print job to correctly print, is sent to printer 200.In general, using PDL (page description language, Page
Description Language), this is a kind of description content of pages that reality output result bitmap is described on higher level
Language.Private mark is typically shown as in print job by the PDL unit point of PDL language description.In addition, in order to control printer
Some behaviors, printing driving also use PJL (print job language, Print Job Language), this is to define printing to make
The print language of JOB layers of industry control, is typically shown as plain code in print job.
Generally, the PDL of each has respective advantage and disadvantage, so it is directed to different printing demands, each printing
Machine 200 usually can all support more than one PDL.Common PDL has PCL, HostBase, PostScript etc..In printing visitor
End needs to install the relevant print driver of this kind of PDL if necessary to printing to certain PDL at family end 100.Printer
200 need to parse PDL order after receiving print job correctly to export print result.If made in print client 100
If the printing driving that do not supported with 200 hardware end of printer prints, print job can be construed to messy code printing by printer.
For example, if print client 100 printing driving support PCL language, and printer 200 only supports HostBase with
PostScript language, then printer 200 then cannot correctly interpret the print job of the creation of print client 100, to beat
Print off the paper of messy code.
In addition, as indicated in the background, user sometimes can initiate print out task because of maloperation, in printing content
When having more number of pages, biggish waste can be generated.
Fig. 2 is the simplified block diagram of intelligent printing system according to an aspect of the present invention.As shown in Fig. 2, print client
100 pass through network connection to intelligence printer 200.The print client 100 can be catv terminal or wireless terminal.For example,
Print client 100 can be PC computer, tablet computer, mobile phone, personal digital assistant (PDA) etc..The network can be often
The office network seen, such as the Intranet that company or office create.Note that illustrating only an intelligence printer in Fig. 2
200, but it is clear that there may be more intelligence printer in the network of a company or office, these intelligence printer it
Between can be in communication with each other.
In print client 100, it is mounted with printing driving to realize print client 100 to intelligence printer 200
Printing function.Printing driving is receiving what user initiated from some application program (for example, Word, PDF application program etc.)
After print out task, the number of pages of printing content is first checked for, if number of print pages is more than customized threshold value, user can be reminded true
Recognize, only just will continue to print procedure after user's confirmation.
Fig. 3 is to show the flow chart of the process 300 executed by print client 100.Shown in Fig. 3, the process 300 packet
It includes:
Step 301: after user initiates print out task, calling the DrvStartDoc function of printing driving first；
Step 302:DrvStartDoc function obtains the JOB_INFO_2 structural body of target print content, to read JOB_
TotalPages field in INFO_2 structural body, the number of pages of TotalPages field instruction printing content；
Step 303: judging whether number of pages indicated by Totalpages is more than threshold value；At this point, advancing if being more than threshold value
To step 304, step 306 is otherwise marched to；
Step 304: popping up confirmation message frame, in the user interface of print client 100 to request user to confirm；
Step 305: judging whether user confirms；If user confirms at this time, process marches to step 306, otherwise advances
To step 307；
Step 306: continuing print procedure, i.e. printing driving generates print job according to the target print content；
Step 307: cancelling printing.
Specifically, when generating print job, print job includes the part PJL and PDL unit point, wherein the part PJL be with
What plain occurred.According to an aspect of the present invention, printing driving can be added in the part PJL can uniquely identify itself body
The printing of part drives identity information, such as printing driving identity information to can be the globally unique identifier of printing driving
(PrintDriverGUID) combination of the version number (DriverVersion) driven with printing.
In addition Fig. 2 shows the block diagram of intelligence printer 200.As shown in Fig. 2, intelligence printer 200 includes Transmit-Receive Unit
210, Transmit-Receive Unit 210 can be communicated with print client 100, to receive the print job from print client 100.In addition,
Transmit-Receive Unit 210 can also be communicated with other intelligence printer (not shown) in network, such as the printing that itself is not supported is made
Industry, which is sent to, supports that other printers of the print job are printed, this is described below.
Intelligence printer 200 further includes print unit 230, storage unit 240 and display unit 250.Print unit 230
For executing printing function, necessary configuration information and data, such as blacklist and white list are stored in storage unit 240.
Specifically, in blacklist include the printing driving identity information for the printing driving that print unit 230 is not supported, and wrapped in white list
Include the printing driving identity information of the printing driving of the support of print unit 230.In addition, being also stored with printing in storage unit 240
Machine pond includes the Printer Information of other printers in the network where intelligence printer 200, including printer in printer pond
The PDL etc. that address and printer are supported.User interface can be shown on display unit 250, for the interaction with user.
It according to an aspect of the present invention, may include interception unit 220 between Transmit-Receive Unit 210 and print unit 230, it should
The print job that interception unit 220 can not support print unit 230 executes interception, will only be supported by print unit 230
Print job passes to print unit 230 and is printed.
Fig. 4 is to show the specific block diagram of interception unit according to an aspect of the present invention.As shown in figure 4, interception unit
220 may include black and white lists judging unit 221, resolution unit 222, black and white lists edit cell 223 and searching unit 224.
After Transmit-Receive Unit 210 receives print out task, interception unit 220 is passed it to first.Interception unit 220
Black and white lists judging unit 221 to first determine whether included in the print job whether printing driving identity information is included in black
In list or white list.
If printing driving identity information included in the print job is included in blacklist, print job directly quilt
It intercepts, without being passed to print unit 230.If printing driving identity information included in the print job is included in white list
In, then print job is passed to print unit 230 and is printed.
Blacklist and white list can initially be manually set by user, and can be constantly updated in use, such as
It is described below.In order to ensure the uniqueness of printing driving identity information, printing driving identity information can be printing driving
The combination of the version number (DriverVersion) of globally unique identifier (PrintDriverGUID) and printing driving.
If the printing driving identity information of print job needs specifically to solve neither in blacklist nor in white list
The print job is analysed, to determine the PDL type of the print job.
Specifically, resolution unit 222 can parse print job to obtain the PDL print language information of print job, thus
Judge whether the PDL print language of the print job is supported by print unit 230.Typically, PDL may include three kinds of main classes
Type, i.e. PCL, HostBase, PostScript, and HostBase has different compression types.
Resolution unit 222 can parse the part PJL of print job to obtain PDL information, and Fig. 5 A, Fig. 5 B show this feelings
Shape.Print job includes PJL (plain code) partially with PDL (private mark) part, and resolution unit 222 can pass through [the@PJL of the part PJL
ENTER LANGUAGE=PCLXL] judge the type of PDL.As shown in Figure 5A and 5B, resolution unit 222 can pass through parsing
PJL learns that the type of PDL is respectively PCL and PostScript in part.
For HostBase, it further includes a variety of compression types, even if printing driving and print unit 230 are all supported
HostBase, but if the compression type supported is different, also will appear Print Garbled.Therefore, for this situation, parse
Unit 222 can parse the part PJL first to obtain preliminary PDL print language information, such as HostBase, then resolution unit 222
Further PDL unit point is parsed according to the preliminary PDL print language, to obtain accurate PDL print language information, is such as schemed
Shown in 5C and 5D.
By parsing, if the PDL of discovery print job is supported by print unit 230, print job, which is delivered to, is beaten
Impression member 230 to be printed, meanwhile, black and white lists edit cell 223 can by the printing of the print job drive identity information
It is added in white list.On the other hand, the print job is intercepted if not supporting, and black and white lists edit cell 223 can incite somebody to action
The printing driving identity information of the print job is added in blacklist.
More preferably, interception unit 230 may also include searching unit 224, after print job is intercepted, searching unit
224 can search in printer pond in storage unit 240 with the presence or absence of the printer for the PDL for supporting the print job.It is printing
In the case where the printer that there is the PDL for supporting the print job in machine pond, the user interface of display unit 250 shows these dozens
The IP address and printer name of print machine are for selection by the user.Additionally or alternately, user interface can prompt user
Input the IP address of other spare printers.In response to selecting or inputting for user, Transmit-Receive Unit 210 can forward print job
To the IP address of corresponding printer.
On the other hand, if there is no the printers for the PDL print language for supporting the print job in printer pond
In the case of, user interface only prompts user to input the IP address of other spare printers, in response to the input of user, Transmit-Receive Unit
210 can be forwarded to print job the IP address of corresponding printer.
Fig. 6 shows shown user interface after print job is intercepted.User is by selecting other alternative printings
Machine, or printer IP address is directly inputted, other printers, which are sent, by print job prints.
Fig. 7 shows the flow chart of Intelligent printing method 700 according to an aspect of the present invention.As shown in fig. 7, the printing
Method 700 the following steps are included:
Step 701: sending print job from print client to intelligence printer；
Step 702: the print job from the print client is received at the intelligence printer；And
Step 703: interception being executed to the print job that do not support at the intelligence printer, is beaten with only printing by the intelligence
The print job that print machine is supported.
Fig. 8 shows the process of the method 800 intercepted according to an aspect of the present invention to the print job that do not support
Figure.As shown in figure 8, the hold-up interception method 800 includes:
Step 801: obtaining the printing driving identity information of print job；
Printing driving identity information may include that can pass through the portion PJL of parsing print job in the part PJL of print job
Divide to obtain printing driving identity information.Since printing driving identity information is uniqueness for printing driving, because
This, drives identity information that can uniquely identify a printing driving by the printing.
Step 802: judge whether printing driving identity information is included in blacklist, if in blacklist, process row
Step 808 is proceeded to, step 803 is otherwise marched to:
The printing driving identity information that the printing driving that do not support is stored in the blacklist established at intelligence printer, leads to
The judgement of blacklist is crossed, the print job that can be not supported with Direct Recognition.
Step 803: judge whether printing driving identity information is included in white list, if in white list, process row
Step 807 is proceeded to, step 804 is otherwise marched to:
The printing driving identity information that supported printing driving is stored in the white list established at intelligence printer, leads to
The judgement of white list is crossed, the print job that can be supported with Direct Recognition.
Step 804: parsing print job to obtain the PDL print language information of print job；
In one example, the part PJL of direct print job can be obtained PDL print language information, and in another example
In, the part PJL of print job can be parsed first to obtain preliminary PDL print language information, then be beaten further according to the preliminary PDL
Print language message parses to obtain PDL print language information the PDL unit point of print job.
Step 805: judging whether the PDL print language of print job is supported, process marches to step if supporting
806, otherwise march to step 809:
Step 806: the printing driving identity information of print job is added in white list；
It encounters the print job of the generation driven by the printing again afterwards, then can judge simply by white list
And it is printed.
Step 807: to printing job execution printing；
Step 809: the printing driving identity information of print job is added in blacklist；
It encounters the print job of the generation driven by the printing again afterwards, then can judge simply by blacklist
And it is directly intercepted.
Step 808: after print job interception, forwarding the intercepted print job.
In one example, it can search in printer pond with the presence or absence of the printer for the PDL for supporting the print job.It is printing
In the case where the printer that there is the PDL for supporting the print job in machine pond, this can be shown in the user interface of intelligence printer
The IP address and printer name of a little printers are for selection by the user.In response to the selection of user, intelligence printer can will beat
Print operation is forwarded to the IP address of corresponding printer.
On the other hand, if there is no the printers for the PDL print language for supporting the print job in printer pond
In the case of, the IP address that user interface can prompt user to input other spare printers can will be printed in response to the input of user
Operation is forwarded to the IP address of corresponding printer.
In another example, even if there is the printer for the PDL for supporting the print job in printer pond,
In addition to shown in user interface these printers IP address and printer name for selection by the user other than, can also be in user circle
Face prompt user can input the IP address of other spare printers.
