Mystery. I would suspect the printer driver. Don't know.
To avoid working the problem and fix the symptom. Select/Copy all
the text it Notepad. Save it as file in Notepad. Then open that new
file in Wordpad. All the formatting, including fonts, will have been
stripped out. May clear it.
Also, try another font.

Hi!
1) This is NOT a printing problem. Printing will only produce what is
visible in the document window. The double line spacing is apparent in
the document window. This problem has to be fixed at the document level.
2) Font formatting and paragraph formatting are 2 completely different
things. Since, "All the font type and size is uniform" in the document,
this is NOT a font formatting problem. Consequently, there is no point
in "stripping out" "all the formatting, including fonts". Opening the
document in Notepad to strip all formatting would be overkill.
3) All that needs to be done is to change the double line spacing to
single line spacing. This does not require to open the document in
another (plain text) editor. Here is how to proceed in WordPad which
lacks a line spacing paragraph formatting function:
a) Select the "faulty" lines with double line spacing.
b) Cut them to the Windows Clipboard (CTRL+X).
c) Use the WordPad "Edition | Paste Special" menu command and select
"Non formatted text" to insert the cut lines back into your document.
The "faulty lines" will be back, but with single line spacing. The
original font formatting will be kept.
