Creating and binding CSS for the 'print version' for the MODX site

There's a website.

It is necessary that when you try to send a page to print through the standard dialog (CTRL+P) or browser menu, only the content is printed directly without navigation, header and other elements of the site design.

Text and image styles placed in the content when printing are desirable to save.

Example of a page that can be printed:
Texto oculto

The site is built on the CMS MODX Revolution 2.1.3-pl (traditional).

I will answer the rest of the questions by phone or mail.

Deadline = April 3rd.
