With a Mac (running OSX Mavericks), I can do a screenshot or individual window 
shot.

To take a screenshot of a window:

Press Command-Shift-4. The pointer changes to a crosshair pointer.
Press the Space bar. The pointer changes to a camera pointer.
Move the camera pointer over a window to highlight it.
Click your mouse. To cancel, press the Escape (esc) key before you click.
Find the screenshot as a .png file on your desktop.

First I use Chrome to pull down the pdf.
Chrome, seeing it's a pdf, automatically gives you fade-away + and - controls
in the lower right of the browser window.  What I did (for personal use only)
was just manipulate the view size and scroll up/down, left/right until it's
readable and I have a reasonable bit of the overall poster to print.
Took about 7 window shots that way to get the whole thing.

"W.L." provided this URL, for a poster that shows
commonly used commands for RHEL 5, 6, and 7:

https://access.redhat.com/sites/default/files/attachments/rhel_5_6_7_cheatsheet_27x36_1014_jcs_web.pdf

It is a large poster (approaching the Rosetta Stone in size),
but it is very useful for understanding what's what in RHEL7.
This, plus the man pages for the tools, is a good approximation
of what I was asking for.


Reducing it to manageable size might involve:

1) Using Imagemagick "convert" with increased density
    to convert the image into a huge png.

2) Using "gimp" to move chunks of the image around,
then crop them into 4 page size png images.

3) Using "convert" again to make a 4 page pdf out of
those images.

This may be a violation of copyright, so I would never
ever EVER do this.  If copies of a 4 page rhel pdf ever
show up in your mailbox, do the right thing with them.
