A digital planner that prints badly is worse than one that does not print at all, because you find out after using the paper. Most bad prints come from one of five settings, and all five are decided before the first page comes out.
Every planner in the vault ships print-ready in A4 and Letter. This is how to get them onto paper properly.
Turn off fit to page
This is the one that ruins most prints.
Print dialogs default to something called Fit to Page, Shrink to Fit, or Scale to Fit depending on the software. It scales the document down by a few percent so nothing can possibly be clipped by the printer's unprintable edge.
The result is a page with everything slightly smaller and a uniform white border around it. On a planner this is immediately visible, because the grid no longer lines up with the margins the layout was designed around, and a two-sided print has the front and back very slightly misaligned.
Set scaling to 100%, Actual Size, or None. Our A4 and Letter exports already carry a safe margin, so nothing is clipped at full size.
Tip. Print one page at 100% before committing to fifty. Measure the outer margin with a ruler: it should be even on all four sides. If it is not, the scaling setting did not take.
Duplex and the flip edge
Print double-sided if your printer supports it. Beyond the obvious paper saving, a single-sided planner is twice as thick and behaves badly in any binding.
The setting that matters is the flip edge, described as Long Edge or Short Edge binding. For a portrait planner you want Long Edge, which flips like a book. Short Edge flips like a calendar and every other page comes out upside down.
For the landscape exports it is the reverse: Short Edge is the one that reads correctly.
If your printer has no duplex, print odd pages, then reload and print even pages in reverse order. Run a four-page test first to work out which way your particular printer wants the stack turned over, because it is genuinely different between models and getting it wrong on fifty sheets is a bad afternoon.
Leave a binding gutter
Decide how you are binding before you print, because it changes the margin you need.
Spiral or coil binding punches a row of holes down one edge and eats roughly 10mm. Our files leave enough inner margin for this at 100% scale, so no adjustment is needed.
Ring binder punches two or four holes and eats a similar amount, but positioned differently. Again, the default margin covers it.
Disc binding, the mushroom-shaped punches, needs slightly more clearance than either. If you are using discs, print with a 5mm additional left margin using your print dialog's margin option rather than scaling the page down.
Whatever you choose, punch a test page and hold it in the binding before printing the rest. The thing you are checking is that the punch does not cut into the tab rail, because a bound planner with half a tab column is unusable and cannot be fixed.
Paper weight
Standard copier paper is 80gsm in most of the world, 20lb in the US. It works, and if you are printing a month at a time to try a layout, use it.
For anything you intend to keep, 100 to 120gsm is the meaningful upgrade. It stops fountain pen and fineliner ink showing through to the reverse, and it survives being carried around for a year. The jump from 80 to 100 costs very little and is the single best improvement available.
Above 120gsm you are into cardstock, which is worth it for dividers and tab pages and unnecessary for the body. Many home printers also struggle to duplex anything heavier than 120gsm, so check before buying a ream.
If you use highlighters, test one on your chosen paper first. Some coated papers that look lovely cause highlighter to smear the printed ink underneath.
A note on colour. Every planner in the vault prints legibly in greyscale, because the layout uses weight and fill rather than colour to separate things. If your printer is monochrome, nothing is lost beyond the accent on the current day. Printing in colour on an inkjet costs considerably more per page and gains very little on a planner you are going to write over anyway.
Print in batches
The last piece of advice is the one that saves the most paper.
Do not print a year. Print twelve weeks.
Three months is enough to find out whether the layout genuinely suits you, cheap enough that abandoning it costs little, and short enough that you can switch to a different layout without wasting anything. Print the next twelve weeks when you are two weeks from the end.
Batch printing also means you can adjust. Members frequently start with the Weekly Vertical, discover they want more notes space, and move to the Weekly with Habits for the next batch. With a year printed and bound, that switch is not available.
This is also the strongest practical argument for undated files. An undated planner prints in batches without waste, because the spreads you have not printed are not tied to dates that will pass. A dated file printed in March has already lost January and February whether you print them or not.
The free customizer will generate a single month in A4 or Letter for exactly this purpose: print one month, live with it, and only then decide what to commit paper to.
