Printing off census images

[JBee]

I'm having terrible trouble printing off the image of a census off ancestry as I like to have paper copies.

If I use the print above the image it comes out quite small.

If I right click on it I only get a portion - the same as if I email it to myself.
Even tried clicking file and changing page setup to no avail.

How can I get a full size copy (that I can read!! lol)?

What am I doing wrong?
Any suggestions greatly appreciated as I have loads to print off to get my files up to date.
