[0002] This invention relates to the field of printed image display technology, and more specifically, to a print preview method, apparatus, device, and storage medium. Background Technology

[0003] Printers are ubiquitous in daily life and have a wide range of uses. They can be broadly categorized into several types, including dot matrix, inkjet, laser, thermal, and thermal transfer printers. Regardless of the type, all printers face the challenge of delivering print quality that meets user expectations. Common print previews simply generate print data on a host computer (computer or mobile phone) and then send it to the printer for direct printing, only predicting the page layout.

[0004] In existing technologies, users cannot predict the impact of the printer's real-time status and configuration parameters on printing before printing, nor can they predict whether the printing effect will meet their expectations. They can only obtain the actual printing effect through the printer or the printed sample after the print job is completed, or speculate on the problems that have occurred with the printer. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0056] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0058] Depending on the context, the word "if" as used here can be interpreted as "when," "when," "in response to determination," or "in response to detection." Similarly, depending on the context, the phrase "if determination" or "if detection (of the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when detection (of the stated condition or event)," or "in response to detection (of the stated condition or event)."

[0059] The terms "first" and "second" used in the embodiments are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first" and "second" can be interchanged in a specific order or sequence where permissible. It should be understood that the objects distinguished by "first" and "second" can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein.

[0060] like Figure 1 As shown, the first embodiment of the present invention provides a print preview method, which can be executed by a print preview device, and includes at least the following steps:

[0061] S101 establishes a communication connection with the printer.

[0062] S102, when a print preview instruction is received, the content to be printed and the status parameters returned by the sensor are obtained; wherein, the status parameters include the real-time status of the printer and relevant parameters affecting the print preview.

[0063] In this embodiment, the print preview device can be a smart terminal device with a display interface, such as a mobile phone, tablet computer, laptop, or computer. It can establish a communication connection with the printer via wired or wireless means (e.g., Bluetooth, Wi-Fi, USB) to obtain status parameters transmitted from the sensor. The sensor can be built into the printer or originate from a device connected to the printer, such as a camera, scanning component, or the print preview device itself.

[0064] The real-time status of the printer refers to the actual working status of the printer, which may include consumable balance, printhead working status, printhead temperature, print queue workload, etc.

[0065] The parameters affecting print preview can be printer resolution, printable colors, print quality, paper color, paper damage, ribbon color, preview display brightness, etc. These can be the printer's own printing parameter configurations or parameters detected by sensors from related devices connected to the printer. They can affect the actual printing quality, and this invention does not impose any specific limitations.

[0066] In this embodiment, the print preview device is equipped with common office software such as Office, WPS, Adobe Reader, and iReader, which can preview the content to be printed.

[0067] S103, perform print preprocessing on the content to be printed based on the status parameters, and generate a print preview page.

[0068] Unlike typical print preview methods, in this embodiment, different printer status parameters correspond to different print preprocessing methods. Therefore, the print preview page generated after print preprocessing based on the status parameters can simulate the real printing effect, thereby predicting the impact of the status parameters returned by the sensor on the printing result, facilitating timely adjustments, and reducing the occurrence of printing errors.

[0069] S104, The print preview page is displayed so that the user can view the print result.

[0070] In this embodiment, displaying the print preview result on the print preview device's display interface facilitates the user's judgment on whether the print effect meets expectations. Therefore, when the print effect meets expectations, the content to be printed can be sent to the printer for printing; otherwise, the user can anticipate printer malfunctions based on the print effect and make necessary adjustments before printing.

[0071] In summary, by preprocessing the content to be printed based on the printer's real-time status and relevant parameters affecting the print preview, and then displaying the generated print preview page, the real printing process can be simulated. This allows for a preview of the printer's real-time status and the impact of relevant parameters on the print preview on the printing effect. Based on the print effect, a decision can be made on whether to proceed with the printing operation, thus improving the utilization rate of printing consumables.

[0072] Please see Figure 2 As shown, based on the above embodiments, in a preferred embodiment, the status parameter includes the remaining consumable quantity; then step 103 specifically includes:

[0073] Determine the required amount of consumables based on the content to be printed;

[0074] Determine whether the remaining amount of consumables is greater than the required amount of consumables;

[0075] If so, the content to be printed will be fully displayed on the print preview page;

[0076] If not, then a portion of the content to be printed will be displayed on the print preview page according to the ratio of the remaining consumables to the required consumables.

[0077] The consumables can be ribbons, toner, printing paper, etc., which are consumables in the printing process, and the remaining consumables will continuously decrease as printing continues.

[0078] In this embodiment, when the remaining consumables amount is greater than the required amount, it indicates that the consumables are sufficient and will not affect the printing effect. At this time, the complete content to be printed can be obtained. When the remaining consumables amount is less than the required amount, the consumables are insufficient to print the current content to be printed. The content to be printed needs to be partially displayed according to the ratio of the remaining consumables amount to the required amount. For example, when the ratio of the remaining consumables amount to the required amount is 1:2, half of the content to be printed is displayed on the print preview page.

[0079] Based on the above embodiments, in a preferred embodiment, the status parameter includes the current temperature of the printhead; then step 103 specifically includes:

[0080] Obtain the temperature range during normal printhead operation;

[0081] Determine whether the current temperature of the print head is within the temperature range;

[0082] If so, the content to be printed will be displayed at normal density on the print preview page;

[0083] If not, the concentration to be displayed is determined based on the difference between the current temperature and the temperature range, and the content to be printed is displayed on the print preview page at the concentration to be displayed.

[0084] In this embodiment, when the printhead temperature is too low or too high, unclear printing and poor quality are likely to occur.

[0085] When the current temperature of the printhead is outside the specified temperature range, it indicates that the printhead is either underheating or overheating. The concentration to be displayed needs to be determined based on the difference between the current temperature and the specified temperature range. Specifically, when the current temperature is greater than the maximum value of the specified temperature range, the concentration to be displayed is greater than the normal concentration, and the larger the difference between the two, the greater the concentration to be displayed. When the current temperature is less than the minimum value of the specified temperature range, the concentration to be displayed is less than the normal concentration, and the larger the difference between the two, the smaller the concentration to be displayed.

[0086] Please see Figure 3 Based on the above embodiments, in a preferred embodiment, the state parameter includes the working state of the heating point on the print head; then step 103 specifically includes:

[0087] Obtain the working status of each heating point on the print head;

[0088] Determine if any heating points are in a faulty state;

[0089] If so, retrieve the column corresponding to the heating point in the fault state, and render the corresponding column on the print preview page to generate a white line;

[0090] If not, the content to be printed will be displayed normally on the print preview page.

[0091] In this embodiment, when the heating point on the print head is in a faulty state (such as short circuit or malfunction), the corresponding column on the print preview page cannot be printed normally. It is necessary to render the column corresponding to the faulty heating point as a white line to obtain a realistic printing effect.

[0092] Based on the above embodiments, in a preferred embodiment, the status parameters include the paper damage status; then, based on the status parameters, the content to be printed is preprocessed for printing, and a print preview page is generated, specifically including:

[0093] Obtain a scanned image of the paper to be printed;

[0094] Determine whether the paper is damaged based on the scanned image;

[0095] If so, the missing parts in the scanned image will be displayed on the print preview page, and the content to be printed will be displayed according to the missing parts.

[0096] If not, the content to be printed will be displayed in full on the print preview page.

[0097] In this embodiment, the printer can be connected to a matching scanning component. The scanning component has a built-in sensor that can acquire a scanned image of the paper and transmit it back to the print preview device. When the print preview device determines that the paper is damaged, it can display the damaged area on the print preview page to approximate the actual printing effect.

[0098] Of course, in some other embodiments, the printer can be connected to a matching camera component, which can acquire the paper color and ribbon color, and display the corresponding paper background and font colors on the print preview page. In other embodiments, the printer can also be connected to the print preview device itself and acquire the status parameters of the print preview device, such as if the current phone brightness is low or the screen is from a different supplier, and adjust the original image according to the current brightness and supplier color rendering, so that the preview result presented on the print preview page is always as close as possible to the actual printing effect.

[0099] Based on the above embodiments, in a preferred embodiment, it further includes:

[0100] When it is determined that the print preview page is abnormal;

[0101] A printing error message is displayed on the print preview page.

[0102] In this embodiment, the printer's real-time status is constantly changing, and abnormal situations often occur, such as insufficient consumables, overheating of heating elements, malfunction, or nozzle blockage. These abnormalities will result in incomplete display, low density, white lines, and other issues on the print preview page. Corresponding printing error messages can be displayed on the print preview page to remind the user of these abnormalities.

[0103] Please see Figure 2 As shown, in one specific implementation, when the print page is not fully displayed, a corresponding print error message can be displayed on the print preview page: "Due to insufficient ribbon, the mask area cannot be printed."

[0104] Please see Figure 3 As shown, in another specific implementation, when white or black lines appear on the printed page, a corresponding printing error message can be displayed on the print preview page: "White / black line areas cannot be printed normally due to printhead damage."

[0105] It should be noted that when a printing error message appears on the print preview page, users can decide whether to continue printing based on the print quality: for example, if the print preview page displays a "low ribbon" error message, but there is no printout in the corresponding area, or the user finds it unacceptable, printing can continue. Similarly, if the print preview page displays a "black line" error message, but the printout in the corresponding area is minimal, or the impact on print quality is minor, printing can continue.

[0106] Please see Figure 4 In a preferred embodiment, based on the above embodiments, the method further includes:

[0107] Obtain the key information that needs to be displayed in a floating position;

[0108] A floating window containing the key information is generated based on the state parameters;

[0109] The floating window is displayed on the print preview page.

[0110] The key information may include one or more of the status parameters, which can be pre-defined and are not specifically limited in this invention.

[0111] For example, you can pre-set key information to be displayed in a floating manner, such as the printer's remaining battery power, printing progress, and consumables remaining, so that the printing status can be obtained in real time during the printing process.

[0112] In this embodiment, the print preview device can actively query the status parameters returned by the sensors in real time and display the pre-set key information on the print preview page in real time. This allows users to easily make timely adjustments to the print process based on the key information on the print preview page.
