Your calendar prints with the outer grid lines, the last row of dates, or the month title sliced off for two reasons working together: every home printer has a strip near the paper edge it physically cannot reach, and the print scale is often set to enlarge the page past what fits. Fix those two and the cutoff goes away.
Here is why it happens and the exact settings to change, whether the clipping is on one edge or all four.
The unprintable margin every printer has
Start with the part that isn't your fault. No home inkjet or laser printer can put ink all the way to the edge of the sheet. Each one grips and rolls the paper as it feeds, so it leaves an unprintable border of roughly 0.2 to 0.25 inches (5 to 6 mm) on every side. Anything sitting in that strip, an outer grid line or a date flush to the edge, simply falls off the page.
If your calendar was designed edge to edge with no white margin, this alone will clip it. The cleanest fix is to give the page a little room to breathe before it prints, which the guide to adjusting margins before printing walks through step by step.
Check the scale before you blame the printer
The second cause is scale. When your print dialog is set to Fit, Fill, or any percentage above 100%, it enlarges the page so the outermost edges push past the printable area. Borderless mode does the same thing on purpose, growing the image 2 to 3 percent to erase the white edge, which can shove the last grid line off the sheet.
Open the print dialog, set Scale to 100% or Actual size, and turn off Fit to page. If the whole grid then sits slightly off-center, the centering guide shows how to line it up.
When only one edge is cut
Clipping on a single side usually means a paper size mismatch. A file built for Letter (8.5 by 11 in) sent to A4 paper (210 by 297 mm), or the reverse, does not line up, so one edge clips while the opposite side gains extra white space. A4 is a touch narrower and taller than Letter, which is exactly why the right edge or the bottom row tends to disappear.
Set the paper size in the print dialog to match the sheet actually loaded in your tray, not whatever size the file defaults to.
The reliable fix: fit to printable area
When you can't tell what's causing the clip, one setting solves most cases: choose Fit to printable area (sometimes labeled Shrink oversized pages). It scales the page down by a hair so the full design lands inside the printer's safe zone. You lose a sliver of size, but nothing gets cut.
This is the opposite of enlarging, and it is the setting to reach for when the paper size and the file don't match. The full walk-through lives in the main calendar printing guide.
Pick a design with built-in margins
The surest way to never see a clipped edge again is to start from a layout that keeps its content away from the paper edge. A plain printable blank calendar leaves a comfortable white border on all four sides, so even a slightly enlarged print stays intact.
If you want a bolder look, the designed template gallery marks which files run to the edge and which hold a safe margin, so you can choose one that prints clean on a home printer.
