I was considering to work on tdf#73398 and tdf#107192

The claim there is that there is no information about the syntax for printing page ranges in Writer.
[That seems to be right. I could not find anything in my search attempts.]
My proposed solution:
Make a new page with:
<h1>Selecting what to print</h1>
<h2>Printing a single page</h2>
<ol> procedure
<h2>Printing a range of pages</h2>
<ol> procedure
<h2>Printing a selection of text or graphics</h2>
<ol> procedure
and then link that page into the main print page (https://help.libreoffice.org/7.1/en-US/text/shared/01/01130000.html) under the "Printing text documents list.
How does that sound?
