Print with a duplex capable printer
Print EVEN and ODD pages separatly
If your printer cannot print on both sides of pages, then there is a simple work around to this problem.
First print only the ODD pages (1,3,5...). Do not remove the printed pages until the printer has finished.
When the ODD pages are printed, take them (all at once) and put them back in the printing tray, PRINTED SIDE UP, and HEAD TOWARD the printer.
Finally, go to you document and print only the EVEN pages (2,4,6...).
Different bindings gives you different pratical uses. Standar metal gives you the freedom to add or remove the content of your planner during the year. but they sure use lots of spaces.
On the contrary, coils offers different colors and materials. They are more compact and the let you fold your planner all the way. That saves up space when you have a lot of paper on your desk! But the downside is that they are more difficult the add content during the year.
