Bottom line of text on each page not clear when PDF is made of blog

I am using a new MacBook Air. I wish to save as a PDF a blog posting that I received in my email. To do so:

> I select print - my printer is an HP Color Lasetjet Pro MFP 4301dw;

> in the Print window I select: PDF > Save as PDF;

> I select: Print and saved to an appropriate folder.

The bottom line of text on each page is cut in half horizontally...i.e., the top half of the letters appear on the page in question and the bottom half appear at the top of the next page. 

Then:

> I opened the printer settings and, under Paper Handling, selected: Scale to Fit Paper Size, see attached;

> in the Print window I select: PDF > Save as PDF;

> I select: Print and saved to an appropriate folder.

The problem was "fixed" on about 1/2 of the pages byt remains on the rest.

How can I fully eliminate the problem ?

Thanks in advance.
