PDF Won't Print Correctly: Margins, Scaling and Cut-Off Edges
Short answer
Set the scale to Fit to printable area rather than Actual size or None. Every printer has a physical margin it cannot reach, typically a few millimetres, and a PDF designed to the full page edge loses whatever falls inside it. If pages come out shrunken instead, you have the opposite problem and need Actual size.
On this page
Printing a PDF produces a surprising number of distinct failures, and they get treated as one problem. Content clipped at the edge, pages that come out noticeably small, a document that was three pages on screen and five on paper, blank sheets with only images missing. Each has a different cause.
Nearly all of them come back to one thing: the gap between the page the document was designed for and the area your printer can physically reach.
The unprintable margin
No consumer printer prints to the paper’s edge. The rollers that grip and feed the sheet occupy a strip at each edge, so there is a band around the page that the print head never covers — typically a few millimetres, and not the same on all four sides.
A document laid out to the full page size has content in that band. Something has to give, and the print dialog’s scaling setting decides what.
| Scaling setting | What it does | Result |
|---|---|---|
| Actual size / None / 100% | Prints at the designed size | Edge content is clipped |
| Fit to printable area | Shrinks slightly to fit | Nothing lost, everything slightly smaller |
| Shrink oversized pages | Fit, but only when needed | Usually the safest default |
| Custom scale | Whatever you type | Use when you need an exact size |
“Fit to printable area” is the right answer for most documents. The shrink is small enough that nobody notices, and nothing is lost.
Diagnose it in one look at the paper
| What came out | Cause | Fix |
|---|---|---|
| Edges clipped, text cut mid-letter | Actual size on a full-bleed document | Fit to printable area |
| Everything visibly small, wide white border | Fit applied twice, or wrong paper size | Actual size, check paper |
| Content shifted to one side | Paper size mismatch (A4 vs Letter) | Set paper size to match |
| Page count higher than on screen | Reflow or scaling pushing content over | Actual size, check paper size |
| Blank pages or missing images | Driver rendering failure | Print as image |
That table resolves the large majority of cases. The sections below are for when it does not.
Paper size mismatches
A4 is 210 × 297mm. US Letter is 216 × 279mm — wider and shorter. Neither fits inside the other.
Print an A4 document on Letter at actual size and you lose 18mm from the bottom, which is often a footer, a page number or the last line of a paragraph. Print Letter on A4 and you get a gap at the bottom and clipping at the sides.
Check two places, because they disagree more often than you would expect:
- The print dialog’s paper size, which should match what is in the tray.
- The document’s page size, visible in the PDF’s properties.
Where they differ, either load the right paper or accept a fit-to-page shrink. There is no setting that makes a 297mm page fit on 279mm of paper at full size.
When the print is correct but ugly
Two separate complaints get reported as “printing wrong”.
Everything is faint or streaky. That is the printer, not the file. Run the head cleaning or check the toner. The giveaway is that other documents print the same way.
Scanned pages come out muddy. A scan stored at low resolution looks acceptable on screen, where it is displayed at perhaps 100 pixels per inch, and poor on paper where the printer is working at several hundred. If the scan was compressed aggressively, the artefacts that were invisible on screen become obvious. Printing from a less-compressed version is the only real fix; compressing a scanned PDF while keeping it readable covers getting that balance right in the first place.
Blank pages and missing images
This one looks alarming and usually is not. The printer driver interprets the PDF’s drawing instructions, and some drivers handle transparency, blend modes or unusual font encodings badly. The result is a page missing its images, or blank entirely.
The fix is to stop asking the driver to interpret anything. In Acrobat Reader, Print → Advanced → Print as Image. Other viewers have a similar option, sometimes called rasterise.
This converts each page to a bitmap before sending it, so the driver receives a picture instead of instructions. It is slower, often considerably, and text edges are marginally softer. Against that, it prints reliably when nothing else will.
If one viewer refuses to print a file properly, try another. Chrome, Edge, Acrobat Reader and macOS Preview all use different rendering engines, and a file that defeats one often prints cleanly from another.
Printing a section rather than the whole thing
The page range box accepts more than people use it for. Most dialogs take
1-5, 12, 18-20, and most also offer Odd pages only and Even pages only
for manual double-sided printing.
If you keep printing the same subset, it is worth extracting it once into its own file rather than remembering the range each time. Splitting a PDF covers doing that with the same print dialog.
Printing a form you have filled in
A specific and annoying failure: you fill in a PDF form, print it, and the fields come out empty.
Some viewers treat form field contents as an annotation layer that is excluded from printing by default. Look for a Comments & Forms dropdown in the print dialog and set it to Document and Markups rather than Document.
Safer still, flatten the form before printing. Printing to PDF first — which bakes the field contents into the page — then printing that file on paper removes the variable entirely, and gives you an archive copy of what you submitted.
What to expect
Setting the scale to fit the printable area and matching the paper size resolves most of these on the first attempt. Print one page as a test rather than the whole document; a fifty-page reprint because the footer was clipped is an avoidable annoyance.
The honest limit is edge-to-edge printing. If a document genuinely needs ink to the paper’s edge — a certificate with a border, a design with a coloured background — a consumer printer cannot do it. The commercial approach is to print oversized and trim, which is not available on a sheet of A4 from a desktop machine.
