and displaying prompt information on a page for displaying the equipment information, the consumable information and the state information of the target printer, wherein the prompt information comprises the consumable quantity level of the target printer.
Specifically, the consumable quantity level of the target printer can be determined according to the obtained consumable information so as to reflect the consumable remaining degree of the target printer. The corresponding relationship between the consumable information and the consumable quantity level may be preset, for example, the consumable quantity level corresponding to the remaining paper number <40 is: the consumable amount is less, and the consumable amount grade corresponding to the residual paper of more than 100 is as follows: the amount of consumable is sufficient, etc. The judgment threshold value involved therein may be set as needed. Can show the specific numerical value of consumptive material and the consumptive material volume rank that corresponds simultaneously, different consumptive material volume ranks can show for different colours, for example the consumptive material volume shows for red less to realize reminding the effect.
Optionally, after the device information, the consumable information, and the status information of the target printer are displayed, the method further includes:
and under the condition that a printer switching instruction is detected, re-searching the printer or returning to an upper-level equipment searching interface, wherein the equipment searching interface comprises the searched identifier of the printer.
In the case where a plurality of printers are searched, the user can select one target printer from the searched printers to connect. If the user does not select the printer after referring to the device information, the consumable information and the status information of the target printer, the user can select to switch the printer, that is, a command for switching the printer is triggered, the printer can be searched again, or a previous-level device search interface is returned, the device search interface can include the identifier of the searched printer, and the user can select a target printer again.

and communicating with a port of the target printer based on the printing protocol supported by the target printer so as to send the file to be printed to the target printer.
Specifically, when the user performs printing, the user can follow up to obtain the printing protocol supported by the target printer to communicate with the port, for example: IPP, LPD, RAW.
The Internet Printing Protocol (IPP) referred to in the embodiments of the present application is a standard network protocol for printing on the internet, which allows a user to remotely print and manage a printing job through the internet. The user can control various parameters such as the type of paper used by the printed product, the resolution and the like through the related interface.
A Line Printer Daemon (LPD) is a Daemon installed on a UNIX print server. Its function is to wait for the acceptance of a print job from a customer using the Line Printer Remote (LPR) protocol. When the LPD receives a print job, it first temporarily stores the print job in a print queue, which is a subdirectory of files in which many print jobs are waiting for the LPD to process. When the printing device is idle, the LPD takes the print job from the print queue and passes it to the printer for printing.
The RAW protocol is the default protocol for most printing devices. To send a job in RAW format, the print server will open a TCP stream to the printer network interface. This interface is port 9100 for many devices. After the TCP/IP port is created, the Object Identifier (OID) of the device will be queried using SNMP. If the device returns a value, parse the system file tcpmon. ini for a match. If the printer manufacturer provides specific configuration information for a particular device, then the configuration information has been created ready along with the configuration settings.
Optionally, the communicating with the port of the target printer based on the printing protocol supported by the target printer includes:
determining a target printing protocol with the highest priority from the printing protocols supported by the target printer according to preset printing protocol priority information;
and communicating with a port of the target printer based on the target printing protocol.
According to the method and the device, the priorities of different printing protocols can be preset, namely the preset printing protocol priority information is obtained, one printer can possibly support multiple printing protocols, after the printing protocols supported by the target printer are obtained, the printing protocol with the highest priority can be selected according to the preset printing protocol priority information, and port communication is carried out on the basis of the printing protocol priority information.
Specifically, RAW can be preferentially adopted to push a file to be printed, TCP link is adopted between the file and a port of a target printer, the file to be printed is sent to the target printer, and the printer outputs the file.
Optionally, in this embodiment of the present application, a print payment rule may be set as needed, after the user uploads the file to be printed, the payment amount is calculated and displayed according to the type and the number of the file to be printed and the print payment rule of the target printer, and the user selects a supported payment method to pay.
In the embodiment of the application, the terminal equipment can search the printers in the target range through the preset WeChat applet and establish connection with the target printer, wherein the target printer is the printer searched in the target range; acquiring the equipment information, the consumable information and the state information of the target printer, and displaying the equipment information, the consumable information and the state information of the target printer; to target printer sends and treats the printing file, so that target printer prints treat the printing file, accessible share printer and the online platform that little letter procedure was built, compare traditional print shop and reduced shop and cost of labor, do not have the business hours restriction, in time provide convenient self-service printing service, the user of being convenient for inquires printer device information, consumptive material and state, select the printer to print, can avoid printing in or lack the printer of paper, printing ink, other printers of preferred selection are in order to save time.
Referring to fig. 2, fig. 2 is a schematic flowchart of another printer information query and printing method according to an embodiment of the present disclosure. Wherein, the method comprises the following steps:
201. and searching a printer in a current local area network based on a preset network protocol, wherein the current local area network is the local area network accessed by the terminal equipment.
The printer information query and printing method in the embodiment of the application can be applied to terminal equipment, including but not limited to mobile terminals such as mobile phones.
Specifically, the printer information query and printing method can be realized by means of the wechat applet, and a user can log in the wechat account through the terminal equipment to enter the preset wechat applet.
The wechat applet mentioned in the embodiments of the present application is an application that can be used without downloading or installing, and a user can open the application by scanning a two-dimensional code or by a search function.
If the terminal device accesses a local area network (such as a certain WiFi), the printer can be automatically searched in the current local area network based on a preset network protocol through the preset wechat applet, and the printer device accessing the same local area network can be searched.
The preset network protocol may include an mDNS protocol.
In computer networks, the Multicast DNS (mDNS) protocol resolves host names to IP addresses in small networks that do not contain local name servers. It is a zero configuration service that uses substantially the same programming interface, packet format and operational semantics as unicast Domain Name System (DNS).
In a local area network, the device and the device need to know the physical Address of the other party, i.e. the IP Address (Internet Protocol Address), before communicating with each other, and in most cases, the IP of the device is not a static IP Address, but an IP Address dynamically allocated by the DHCP Protocol. The mDNS mainly realizes the mutual discovery and communication of hosts in the local area network under the condition of no traditional DNS server, uses a port 5353, conforms to the DNS protocol, and uses the existing DNS information structure, name grammar and resource record type.
When an mDNS client needs to resolve a hostname, it sends an IP multicast query message asking the host with the name to identify itself. The target machine then multicasts a message containing its IP address. All computers in the subnet can then use this information to update their mDNS caches. Any host can give up its declaration of a name by sending a response packet with a time-to-live (TTL) equal to zero.
After step 101, step 201, step 202 or step 203 may be performed.
202. And under the condition that the printer is not searched, prompting to carry out manual connection or re-search, and displaying a manual connection key, wherein the manual connection key is used for triggering an equipment address input box, and the equipment address input box is used for inputting the physical address of the printer to be connected.
Specifically, if the printer is not found in the target range, for example, in the current WiFi environment, a corresponding prompt may be performed, for example: "No printers are currently searched for, please attempt to manually connect! "a manual connection button is displayed on the page, the user can click the trigger device address input box and input the device IP address, and after the determination button is clicked, the printer device of the IP address can be connected. Optionally, it may also be detected whether the IP address input by the user is correct, and a prompt is performed when the format of the input IP address is detected to be wrong.
203. In the case where a target printer is searched, a connection is established with the target printer.
If only one target printer is searched, connection can be automatically performed. Whether to connect can also be confirmed manually by the user, similar to step 204.
204. And if at least two printers are searched, displaying the identifications of the at least two printers.
When the terminal device searches for a printer, the identifier of the searched printer may be displayed on the device connection interface in the applet, where the identifier may be a name or a number for identifying the identity of the printer.
By displaying the identifier of the printer, the user can select which printer to connect for printing.
Optionally, the position information of the printer can be displayed, so that the user can accurately find the position of the printer.
After step 204, step 205 may be performed.
205. And when a selection instruction of the identification of the target printer is detected, establishing connection with the target printer, wherein the identification of the target printer is one of the identifications of the at least two printers.
The user can select a target printer from the searched printers to connect, that is, trigger a selection instruction of the identifier of the target printer, so that the terminal device establishes a connection with the target printer.
Optionally, a page may be searched on a device in which a wechat applet is preset, and an IP address of a target printer to be connected is manually input, so that the target printer in the IP address is searched for connection.
After the connection with the target printer is successful, a connection success message may be displayed. The user can select a file to be printed through the applet and print with the target printer. Specifically, reference may be made to the detailed description in the embodiment shown in fig. 1, which is not repeated herein.
Based on the description of the method embodiment, the embodiment of the application further provides a terminal device. Referring to fig. 3, a schematic structural diagram of a terminal device according to an embodiment of the present application is shown, as shown in fig. 3, a terminal device 300 includes:
