[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] The present application embodiment provides a method for obtaining the remaining amount of printer consumables, which can be executed by a computer device, such as Figure 1 As shown, the computer device can establish a communication connection with the target printer according to the IPP protocol, and then obtain the remaining consumables of the target printer. It can be understood that the computer device can be implemented by a server or a terminal. Among them, the terminal can also be called a server. In this embodiment, the method includes Figure 2 The steps shown are:

[0043] Step S201: Establish a communication connection with a target printer according to the IPP protocol to obtain attribute information of the target printer.

[0044] IPP (Internet Printing Protocol) is a network protocol used to print and manage printing services over the Internet.

[0045] The printer for which the remaining consumables are to be determined may be referred to as a target printer.

[0046] The computer device can establish a communication connection with the target printer according to the IPP protocol, and at the same time send a Get-Printer-Attributes request to the target printer to obtain attribute information of the target printer.

[0047] Step S202, parsing the attribute information of the target printer to obtain the current consumables information of the target printer.

[0048] The current supplies of the target printer include various types of supplies, such as ink cartridges, toner cartridges, and paper.

[0049] The current consumables information of the target printer may include a remaining percentage of the consumables or a specific capacity value of the consumables.

[0050] After obtaining the attribute information of the target printer, the computer device may parse the attribute information of the target printer to obtain the current consumables information of the target printer.

[0051] Exemplarily, the current consumables information of the target printer may be obtained through the printer-supply attribute of the IPP protocol, where the current consumables information of the target printer may include:

[0052] The type of supplies (such as ink cartridges, toner cartridges, paper, etc.).

[0053] Current status (e.g., full, low, empty).

[0054] The amount remaining (expressed as a percentage or other unit).

[0055] The following is an example of the target printer's response data:

[0056] { "printer-supply": [

[0057] {"supply-type": "ink", "supply-level": "70%"},

[0058] {"supply-type": "toner", "supply-level": "50%"} ]}Parse the target printer's attribute information, including mapping or standardizing the consumable types. For example: "ink" → ink cartridge; "toner" → toner cartridge; "media" → paper, → indicates mapping or standardization.

[0059] After parsing the attribute information of the target printer, the parsed raw data needs to be cleaned and normalized to filter out abnormal data or redundant information, so as to obtain the current consumables information of the target printer to ensure that the consumables balance, timestamp and other fields of the current consumables information of the target printer are not missing or abnormal.

[0060] Step S203, obtaining the remaining consumables of the target printer according to the current consumables information of the target printer.

[0061] When the current consumables information of the target printer only includes the remaining percentage of the consumables, the remaining percentage of the consumables information may be used as the remaining consumables amount of the target printer.

[0062] When the current consumables information of the target printer only includes the specific capacity value of the consumables, the remaining consumables of the target printer can be obtained according to the specific capacity value of the consumables of the target printer and the total capacity of the consumables.

[0063] In the above-mentioned method for obtaining the remaining printer consumables, a communication connection is established with the target printer according to the IPP protocol, supporting the transmission and statistics of the remaining printer consumables data with higher accuracy, being able to update the remaining printer consumables data in real time, and reducing the lag and error of the remaining printer consumables data.

[0064] In one embodiment, a communication connection is established with a target printer according to the IPP protocol to obtain the attribute information of the target printer. The specific steps are as follows: Figure 3As shown: Step S301, obtain the IP address and port number of the target printer; Step S302, establish a communication connection with the target printer according to the printer attribute acquisition request in the IPP protocol, and the IP address and port number of the target printer; Step S303, receive the information returned by the target printer as the attribute information of the target printer.

[0065] The IP (Internet Protocol) address and port number of the target printer can be obtained; a communication connection can be established with the target printer based on the Get Printer Properties request in the IPP protocol, as well as the IP address and port number of the target printer; the default IPP port is 631. An example of a Get Printer Properties request is as follows (expressed in JSON):

[0066] { "operation": "Get-Printer-Attributes",

[0067] "printer-uri": "http: / / <printer-ip>:631 / ipp / printer"}

[0068] After the computer device establishes a communication connection with the target printer, the target printer can return information to the computer device. Specifically, the target printer will return the properties such as the functions, status information, and consumable types supported by the target printer. The key fields of the returned information include:

[0069] printer-state (current printer state).

[0070] printer-supply (supply status information, such as remaining ink levels).

[0071] media-supported.

[0072] The computer may receive the information returned by the target printer as the attribute information of the target printer.

[0073] In this embodiment, after establishing a communication connection with the target printer, information returned by the target printer is received as attribute information of the target printer.

[0074] In one of the embodiments, the usage trend of the target printer is obtained, and the specific steps are as follows: based on the remaining consumables of the target printer within a set period, a changing trend graph of the remaining consumables of the target printer is obtained; based on the remaining consumables and the total capacity of the consumables, the percentage of the remaining consumables is obtained; based on the percentage of the remaining consumables, an estimated time when the consumables will run out is obtained; and the changing trend graph of the remaining consumables of the target printer and the estimated time when the consumables will run out are used as the usage trend of the target printer.

[0075] According to the remaining consumables of the target printer within the set period, a line graph or a bar graph of the remaining consumables of the target printer within the set period can be obtained as a change trend graph of the remaining consumables of the target printer.

[0076] The remaining consumable percentage can be obtained according to the remaining consumables and the total consumable capacity of the target printer, as shown in formula (1).

[0077] R=Vr / Vt*100% (1)

[0078] Among them, R represents the percentage of remaining consumables, Vr represents the remaining consumables, and Vt represents the total capacity of consumables.

[0079] The estimated time until the consumables are used up can be obtained based on the remaining percentage of the consumables, as shown in formula (2).

[0080] Tempt=tcurrent+R / (dR / dt)

[0081] Among them, Tempt represents the estimated time when the consumables are used up, tcurrent represents the current time, R represents the percentage of the remaining consumables, and dR / dt represents the consumables consumption rate.

[0082] The changing trend graph of the remaining consumables of the target printer and the estimated time when the consumables are used up can be used as the usage trend of the target printer.

[0083] In this embodiment, based on the remaining consumables of the target printer within a set period, a changing trend graph of the remaining consumables of the target printer is obtained; based on the remaining consumables and the total capacity of the consumables, the percentage of the remaining consumables is obtained to obtain the estimated time when the consumables will run out; the changing trend graph of the remaining consumables of the target printer and the estimated time when the consumables will run out are used as the usage trend of the target printer to provide data support for the intelligent management of the target printer.

[0084] In one of the embodiments, the method provided by the present application further includes: using a long connection method or a timed polling method to periodically send a request to obtain printer attributes to the target printer to update the current consumables information of the target printer.

[0085] You can use a WebSocket-based long connection method or a timed polling method to periodically send a request to obtain printer attributes to the target printer and update the current consumables information of the target printer.

[0086] In this embodiment, a long connection mode or a timed polling mode is used to periodically send a request for obtaining printer attributes to the target printer, update the current consumables information of the target printer, and implement real-time monitoring of the current consumables information of the target printer.

[0087] In one of the embodiments, the method provided by the present application further includes: monitoring the changes in the usage trend of the target printer, and when it is found that the usage trend changes abnormally, generating and displaying abnormal alarm information.

[0088] The usage trend of the target printer can be monitored. When abnormal usage trend changes are found, such as when consumables are suddenly consumed too quickly or when consumables report errors, abnormal alarm information is generated and displayed to enable relevant personnel to quickly discover abnormal conditions of the target printer.

[0089] In one of the embodiments, the method provided in the present application also includes: obtaining a monitoring template corresponding to the target printer; determining the consumables and warning thresholds corresponding to the target printer based on the monitoring template corresponding to the target printer; monitoring the remaining consumables of the target printer; and triggering a consumable replacement warning when the remaining consumables of the target printer is lower than the warning threshold.

[0090] After a communication connection is established with the target printer according to the IPP protocol, a monitoring template corresponding to the target printer may be generated.

[0091] The monitoring template defines the monitoring rules and warning thresholds for each type of consumables, including: monitoring fields: remaining quantity, consumable name, status (full / low / empty); warning thresholds: trigger a replacement warning when the ink cartridge is less than 20%; trigger a replacement warning when the toner cartridge is less than 10%. The warning thresholds can be customized by users to adapt to different printing scenarios and needs.

[0092] The following is an example of a monitoring template (JSON format):

[0093] { "printer-model": "HP-LaserJet-2024",

[0094] "monitoring-template": {

[0095] "ink": {"threshold": 20, "unit": "%"},

[0096] "toner": {"threshold": 10, "unit": "%"},

[0097] "paper": {"threshold": 50, "unit": "sheets"}}

[0098] The consumables and warning thresholds corresponding to the target printer can be determined based on the monitoring template corresponding to the target printer; the remaining consumables of the target printer can be monitored; when the remaining consumables of the target printer are lower than the warning threshold, a consumable replacement warning is triggered.

[0099] In this embodiment, the consumables and warning thresholds corresponding to the target printer are determined based on the monitoring template corresponding to the target printer; the remaining consumables of the target printer are monitored; when the remaining consumables of the target printer are lower than the warning threshold, a consumable replacement warning is triggered to let relevant personnel quickly know that the consumables need to be replaced.

[0100] In addition, the present application also designs a universal interface so that the IPP protocol supports multiple printer models and can uniformly manage multiple types of printer devices, thereby improving the compatibility of the method for obtaining the remaining printer consumables provided by the present application.

[0101] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
