Print range in LO 7.2

Since I’ve downloaded this version of LO 7.2, I can’t print more than the first 4 columns wide (16.5cm total) (portrait or landscape format) How do I define printing area. Did not have this problem with the old version of LO. Thank you.
I’ve asked about this in October but the ‘‘edit your question’’ pencil does not work. The proposed answers are confusing. What do I insert in edit print range box ($x$x format).
File type is ods. How do I move the ‘’ by default’’ page break to show all my columns. They should fit in landscape as before with the old version of LO

This are two questions.

Check the Menue, there is another view to check page-breaks. In this you can simply move the page-breaks with the mouse. However if pieces don’t fit you have to resize columns or change margins.
