I also print out my pages and like to keep it to one page per cache.
This is what I do:
Print-NO logs (usually a note will take up much less space if there's information I absolutely must have)
Hide images for each entry-this saves space even for things like winter, wheelchair accessible,evince etc
Right click for print preview
Raise the top margin to just about the page numbers (this way the GC code will still show)
Lower the lower margin bottom edge of the page
Sometimes, but not usually I move out the left and right margins
then...I click on various percentages until it fits to one page
I like to keep my size to 80% or above for my eyes, but will go down as low as 70% if I have to. Below that I print two pages.
When I actually do print I click on the circle for 1 page only
I'm not too tech savvy, but this method has worked out for me.
