Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In a first aspect, an embodiment of the present invention provides a method for detecting configuration security of a printing device, which can quickly obtain configuration information of the printing device and accurately detect whether the configuration is secure for the printing device, thereby improving efficiency and accuracy of configuration security detection of the printing device.
As shown in fig. 1, a configuration security detection method of a printing apparatus according to an embodiment of the present invention includes:
s11, constructing a configuration information acquisition instruction based on a preset language standard;
the preset language standard may be a language rule that the terminal and the printing device are well defined and that both parties can mutually understand and communicate. The terminal may construct a series of instructions for acquiring print configuration information from the printing apparatus based on the standard, thereby knowing how various attributes and parameters of the printing apparatus are configured. Alternatively, in the embodiment of the present invention, the configuration information acquisition instruction may be constructed in a variety, and one instruction may be used to specifically acquire one type of configuration information, or may be used as a general instruction to acquire some type or all of configuration information of the printing apparatus, which is not limited in the embodiment of the present invention.
S12, sending the configuration information acquisition instruction to target printing equipment to be detected, and receiving printing configuration information fed back by the target printing equipment;
in this step, the constructed configuration information acquisition instruction may be transmitted to the target printing apparatus to be detected, as needed. The target printing device can recognize the received configuration information acquisition instruction, respond to the instruction, and feed back the corresponding printing configuration information to the terminal sending the instruction.
S13, comparing the printing configuration information with preset reference configuration information to detect the security of the configuration information of the target printing equipment.
Specifically, after the print configuration information of the target printing apparatus is acquired, the print configuration information may be compared with preset reference configuration information whose security is known, and whether the configuration of the target printing apparatus to be detected is safe or not may be simply determined by detecting whether the security meets the corresponding reference.
According to the configuration security detection method for the printing equipment, provided by the embodiment of the invention, the configuration information acquisition instruction can be constructed based on the preset language standard, the constructed instruction is sent to the target printing equipment to be detected, and after the printing configuration information fed back by the target printing equipment is received, the security of the configuration information of the target printing equipment is detected by comparing the printing configuration information with the preset reference configuration information. Because the configuration information of the printing equipment can be obtained through the computer instruction and the network communication, and the obtained configuration information is compared with the preset reference configuration information, the configuration information of the printing equipment can be quickly obtained, whether the configuration is safe for the printing equipment or not can be accurately detected, and therefore the efficiency and the accuracy of the configuration safety detection of the printing equipment are effectively improved.
Specifically, in one embodiment of the present invention, the language standard preset in step S11 may be a printer job language (PJL, print job language) standard, that is, the configuration information acquisition instruction may be constructed based on the printer job language (PJL, print job language) standard.
According to the difference of the items and types of the configuration information of the printing device, the constructed configuration information acquisition instructions are correspondingly different. Optionally, in an embodiment of the present invention, the configuration information acquisition instruction may include one or more of: identification information acquisition instruction (@ PJL INFO ID), configuration information acquisition instruction (@ PJL INFO CONFIG), product information acquisition instruction (@ PJL INFO PRODINFO), firmware information acquisition instruction (@ PJL INFO BRFIRMWARE), MEMORY information acquisition instruction (@ PJL INFO MEMORY), page number information acquisition instruction (@ PJL INFO PAGECOUNT), STATUS information acquisition instruction (@ PJL INFO STATUS), variable information acquisition instruction (@ PJL INFO VARIABLES), and the like. Alternatively, in another embodiment of the present invention, a wild card may be used to enable one instruction to obtain multiple or all configuration information.
After the configuration information acquisition instruction is constructed, in step S12, the configuration information acquisition instruction may be transmitted to the target printing apparatus to be detected, so as to acquire the configuration information of the target printing apparatus to be detected. Specifically, if the target printing device is connected with the terminal through the network, the configuration information acquisition instruction can be packaged into a data packet message with a corresponding format according to a preset network protocol, and the data packet message is sent to the target printing device. For example, the configuration information acquisition instruction may be encapsulated into data packet messages conforming to the TCP/IP protocol, and these data packet messages are sent to the target printing device through the network, so that the target printing device feeds back its own print configuration information to the terminal according to the configuration information acquisition instruction in these messages.
After the terminal sends the configuration information acquisition instruction, the terminal can wait for feedback of the target printing equipment. If the fed back print configuration information is still transmitted through the network, the terminal may analyze the received message according to the preset network protocol, and then acquire the print configuration message from the analyzed message.
After the print configuration information of the target printing apparatus is obtained, the print configuration information may be compared with the preset reference configuration information in step S13 to detect the security of the configuration information of the target printing apparatus. In this step, the preset reference configuration information is one of configuration information of which the security of the printing apparatus is known. The reference configuration information corresponding to different brands or models of printing apparatuses may be the same or different. In one embodiment of the present invention, the reference configuration information corresponding to the printing apparatuses of various brands or models may be organized into a lookup table and stored. When the target printing equipment to be detected needs to read the corresponding reference configuration information and compare the reference configuration information, the target printing equipment can be directly read from the lookup table, so that a reliable basis is provided for judging the security of the printing configuration information, the judging speed is increased, and the efficiency and the effect of the security detection of the configuration information are effectively improved.
Specifically, in one embodiment of the present invention, the step S13 of comparing the print configuration information with the preset reference configuration information may specifically include:
analyzing the received printing configuration information to obtain the brand and/or model of the target printing equipment;
searching corresponding basic configuration information items in a basic configuration information base by taking the brand and/or model as an index;
comparing each item of the analyzed printing configuration information with the corresponding item in the searched reference configuration information item respectively;
if the comparison result shows that all the configurations are consistent, determining the configuration information security of the target printing equipment;
and if any configuration is inconsistent in the comparison result, determining that the configuration information of the target printing device is at risk.
Because the print configuration information fed back by the target printing device can contain one or more configuration parameters corresponding to the configuration information acquisition instruction, when detecting whether the print configuration of the target printing device is safe, the method also needs to comprehensively examine whether each configuration parameter is safe. In order to avoid missing or repeating the inspected item, in one embodiment of the present invention, the brand and/or model of the target printing device may be used as an index, and corresponding reference configuration information items may be searched in the reference configuration information base, and the corresponding items may be compared after being locked. For example, if the brand and model of the target printing device is Epson I380, an entry corresponding to Epson I380 may be found in the reference configuration information base, and optionally, the reference configuration information in the entry may include, for example, memory information, state information, variable information, and the like.
After finding the corresponding item, each configuration parameter in the parsed print configuration information may be compared with the corresponding item in the found reference configuration information item, for example, the memory information, the state information and the variable information of the two may be compared respectively. It will be appreciated that, in order to make the comparison more comprehensive, as many configuration items as possible may be included in the reference configuration information, and the configuration items included in the print configuration information of the target printing apparatus to be detected may be the same as or different from those in the reference configuration information, for example, may be fewer than those in the reference configuration information, which is not limited by the embodiment of the present invention.
Through the comparison, if the comparison result is that all the configurations are consistent, the configuration information security of the target printing equipment can be determined; if any configuration is inconsistent in the comparison result, it can be determined that the configuration information of the target printing device is at risk.
Further, for the target printing device with risk, in an embodiment of the present invention, after comparing the print configuration information with the preset reference configuration information to detect the security of the configuration information of the target printing device, if the detection result is that the configuration information of the target printing device is at risk, the corresponding configuration in the preset reference configuration information may be recommended to the user. For example, if the automatic sleep time in the print configuration information of the target printing apparatus is 15 minutes and the automatic sleep time in the reference configuration information is 3 minutes, the user may be informed that there is a risk of the automatic sleep time in the formed detection report, and it is recommended to set the automatic sleep time to 3 minutes.
In the above-described embodiment, the reference configuration information is established in advance, but the embodiment of the present invention is not limited thereto. In other embodiments of the present invention, if there is no reference configuration information established in advance, or no corresponding reference configuration information is found in the reference configuration information library, the reference configuration information may also be established by using a printing device with known security, so that the detection of the security of the configuration of the printing device is more flexible. For example, in one embodiment of the present invention, the secure print configuration information of the secure printing apparatus may also be acquired before comparing the print configuration information with the preset reference configuration information; and establishing the preset reference configuration information according to the secure printing configuration information. Alternatively, when the preset reference configuration information is established, an information item may be formed by indexing the brand and/or model of the security printing apparatus, and the newly formed item may be inserted into an existing database.
The configuration security detection method of the printing apparatus provided by the embodiment of the present invention is described in detail below by way of specific embodiments.
As shown in fig. 2, the configuration security detection method of a printing apparatus provided by an embodiment of the present invention may include:
the method needs to be communicated with the network printer, so that the communication with the printer is ensured, equipment such as a switch, a router and the like which can be selectively accessed to the network where the printer is located can also be directly connected with the printer, but the method is not limited to the method and can be communicated with the printer;
s201, constructing a configuration information acquisition instruction according to detection requirements.
Alternatively, the configuration information acquisition instruction may be constructed according to the PJL language. The PJL language is a standard language facing the printer and is composed of a plurality of instructions for inquiring, managing and controlling the printer. The instructions constructed in this step may include: @ PJL INFO ID, @ PJL INFO CONFIG, @ PJL INFO PRODINFO, @ PJL INFO BRFIRMWARE, @ PJL INFO MEMORY, @ PJL INFO PAGECOUNT, @ PJL INFO STATUS, @ PJL INFO VARIABLES, and the like.

And S203, sending the packaged configuration information acquisition instruction to the target printing equipment to be detected.
S204, receiving the data packet fed back by the target printing equipment, and analyzing according to the PJL language standard to obtain the printing configuration of the target printing equipment.
S205, judging whether all configuration information is acquired, if so, executing step S206, otherwise executing step S201.
S206, extracting the standard configuration information of the brand and the model from a preset standard configuration information base according to the brand and the model analyzed in the S204;
in this step, the method for establishing the preset reference configuration information base may be as shown in fig. 3.
S2061, acquiring configuration information of the printing equipment with safe configuration;
specifically, a configuration information acquisition instruction may be constructed and sent to the printing device, and the printing configuration information fed back by the printing device may be received. Unlike the target printing apparatus to be detected, each configuration of the printing apparatus for which security is configured in this step is known to be secure. The reference configuration information is used as a detection basis and standard, and has requirements on the accuracy and safety of the configuration of the printing equipment, so that a new printing equipment or a safe printing equipment can be selected for the operation;
s2062, using the brand and/or model in the obtained printing configuration information as a label, forming a printing configuration information item by the printing configuration information, and inserting the printing configuration information item into a database, wherein the database is the reference configuration information base.
S207, comparing the printer configuration information analyzed in S204 with the reference configuration information extracted in S206, checking whether the values of each item are matched, and recording as an abnormality if the values are not matched with the reference configuration information.
S208, the recommended configuration in the reference information base is given for the abnormal item in S207, and a configuration safety detection report is formed.
For example, if the current value of the timeout is 10S, the reference value is 5S, the two are inconsistent, the risk is prompted, and the proposal is set to 5S;
if the current value of automatic dormancy is 10min, the reference value is 3min, the current value and the reference value are inconsistent, the risk is prompted, and the recommendation is set to be 3min;
if the current value of the watermark attribute is supported, the reference value is not supported, the two values are inconsistent, the risk is prompted, and a driver which does not support the watermark is recommended to be used.
