Print an image or text to a IPP or CUPS Printer

Configuration

Hi,
i have HA on my Pi an there is a Crontab to print a sample image 2 times a week that the paint wont dry out.

Is there any way to print something via HA ? The Printer is already recognized in the IPP Devices but it doesnt support printing.

Does the printer have an embedded web server with a “print test page” function?
