The further inkjet printing device may further include an image obtaining device, where the image obtaining device is electrically connected to the controller and is configured to obtain image information of a printed matter during printing to monitor a printing job, and therefore, the image obtaining device of the inkjet printing device may also replace the image obtaining device of the nozzle device to obtain the image information of the first pattern, the second pattern and/or the third pattern, that is, the nozzle device does not need to additionally provide an image obtaining device, but obtains the image information of the test pattern through the image obtaining device provided in the inkjet printing device.

The ink jet printing device can be a two-dimensional ink jet printer or a three-dimensional ink jet printer.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
