In the embodiment of the invention, the consumption speed of the carbon powder can be predicted more accurately according to a plurality of factors such as the characteristics of printing content, the maintenance state of the printer, the use frequency of the printer, the complexity of a printing task, the printing workload, the basic coefficient of carbon powder consumption, the residual quantity of the carbon powder in the current carbon powder box, the paper quality, the performance of the printer, environmental factors and the like, thereby being beneficial to a user to better plan and manage the carbon powder resource and avoiding the occurrence of waste or deficiency. Different printing tasks and environmental factors can generate different influences on carbon powder consumption, and the printing process can be individually managed according to specific printing requirements and conditions through relevant coefficients, so that the carbon powder consumption is more in line with actual requirements, and the printing economy and efficiency are improved. The introduction of the printer maintenance state coefficient and the printer performance coefficient can prompt a user to pay more attention to the maintenance and the service of the printer, and reasonable maintenance measures can prolong the service life of the printer and reduce the probability of failure occurrence, thereby reducing the maintenance cost and the equipment replacement frequency. The consideration of the paper quality coefficient and the printing content characteristic coefficient is beneficial to selecting more suitable printing parameters and paper types so as to improve the printing quality, and meanwhile, the problem of the printing quality caused by insufficient or excessive carbon powder can be avoided through accurately controlling the consumption of the carbon powder. The introduction of environmental factors enables the printing process to be adjusted to different environmental conditions. For example, in an environment with higher humidity, the ejection amount of carbon powder can be appropriately increased to ensure the printing quality; and in the dry environment, the use of carbon powder can be reduced to save resources. Through accurate calculation and prediction of carbon powder consumption, a user can control printing cost more effectively, unnecessary waste and extra expenditure are avoided, and more economic and efficient printing operation is facilitated.
In a preferred embodiment of the present invention, the step 12 may include:

step 122, byCalculating a dynamic threshold R, wherein ∈>Is the device aging coefficient, +.>Is time, which means the time from the beginning of the printer to the present time, U is the printing intensity, ++>Is a baseline threshold;
step 123, current toner remaining amountA dynamic threshold R, a first printing mode is adopted; current toner remainingAnd the dynamic threshold R is less than or equal to the dynamic threshold R, and a second printing mode is adopted.
In the embodiment of the invention, the use condition of the carbon powder can be known in real time by dynamically calculating the residual quantity of the carbon powder, so that a user can more reasonably manage the carbon powder resource, and the problem can be avoided when the carbon powder is about to be exhausted, thereby ensuring the continuity and the stability of a printing task. In step 121, a nonlinear attenuation coefficient and an environmental influence coefficient are introduced, so that the calculation of the residual amount of carbon powder is more accurate, the nonlinear attenuation coefficient can reflect nonlinear characteristics in the carbon powder consumption process, and the environmental influence coefficient considers the influence of external environmental factors on the carbon powder consumption, thereby improving the accuracy and the practicability of the calculation. In step 122, the dynamic threshold is calculated, so that the influence of equipment aging and printing intensity on carbon powder consumption is considered, the adjustment of the printing mode is more in line with the actual state of the printer and the requirement of a printing task, and the improvement of printing efficiency and quality is facilitated. According to the comparison result of the current carbon powder residual quantity and the dynamic threshold value, the printing mode can be intelligently switched, and when the carbon powder residual quantity is sufficient, the printing speed and the printing efficiency can be ensured by adopting the first printing mode; when the residual quantity of the carbon powder is insufficient, the printer is automatically switched to the second printing mode, so that the carbon powder can be saved and the service life of the printer can be prolonged. This intelligent switching mechanism improves the flexibility and economy of the printing process.
In the embodiment of the invention, the need of manual inspection and adjustment can be reduced by automatically calculating and comparing the residual quantity of the carbon powder with the dynamic threshold value, the labor cost is reduced, and the automation degree and the convenience of the printing process are improved. By dynamically calculating and comparing the residual quantity of the carbon powder with the dynamic threshold value, a large amount of data can be generated for analysis, so that a user can be helped to better understand the use condition of the printer and the consumption rule of the carbon powder, and a powerful basis is provided for optimizing the printing flow and improving the printing management.
