And S104, displaying the print preview page for the user to check the print effect.
In the embodiment, the print preview result is displayed on the display interface of the print preview device, so that the user can conveniently judge whether the print effect meets the print expectation. When the printing effect meets the printing expectation, the content to be printed can be sent to a printer for printing; otherwise, the abnormity of the printer can be judged in advance according to the printing effect so as to carry out printing after relevant adjustment.
In summary, the content to be printed is pre-processed by printing based on the real-time state of the printer and the relevant parameters influencing the printing preview, and the generated printing preview page is displayed, so that the real printing process can be simulated, the influence of the real-time state of the printer and the relevant parameters influencing the printing preview on the printing effect is previewed, whether the printing operation is further executed or not is determined according to the printing effect, and the utilization rate of printing consumables is improved.

When the print preview device judges that the paper is defective, the defective part can be displayed on the print preview page to approximate the real printing effect.
Of course, in some other embodiments, the printer may be connected to a matching camera component, and the camera component may obtain the color of the paper and the color of the ribbon, and display the paper background and the font color of the corresponding color on the print preview page. In other embodiments, the printer may also be connected to the print preview device itself, and obtain the status parameter of the print preview device, for example, obtain that the current brightness of the mobile phone is reduced or the screen is from different suppliers, and adjust the original image according to the current brightness and the color developed by the suppliers, so that the preview result presented on the print preview page is always closest to the real print effect.
On the basis of the above embodiment, in a preferred embodiment, the method further includes:
