Print a PDF right: the settings and the file fixes

The 6 settings that decide every print

Every print dialog, whether Chrome, Edge, Acrobat Reader or macOS Preview, asks the same 6 questions. Answer them deliberately and most PDFs print right the first time.

1. Scale: “fit” or “actual size”. “Scale to fit” shrinks or enlarges the page until it fits inside the printable area of the paper. It is the safe default for reading copy, because nothing gets cut. “Actual size” prints at exactly 100%, and it is mandatory for anything measured: a form with boxes to fill, a sewing pattern, a shipping label, any page with a ruler printed on it. The catch runs both ways: fit quietly shrinks everything by a few percent, and actual size clips whatever does not fit the paper.

2. Paper size. The dialog’s paper setting must match what is actually in the tray. When the PDF’s page size and the paper disagree, this setting plus the scale setting decide whether you get cut edges, shrunken content or clean output. The A4 and Letter mismatch gets its own section below, because it is the single most common cause of cut edges.

3. Flip edge, for double-sided printing. The printer turns the sheet over around one edge, and that edge decides which way the back faces. The rule: portrait documents flip on the long edge, landscape pages and booklets flip on the short edge. Get it wrong and every second page prints upside down, the classic duplex failure. Print pages 1 to 4 as a test before committing a long document.

4. Colour or grayscale. The driver checkbox converts to grey at print time, blind, with no preview. That is fine for a quick draft. For anything that matters, a grayscale file is better, and the ink section below explains why.

5. Page range. You rarely need the whole file. 5-9 prints a run, 2,5,8-10 prints a mix, and most dialogs also offer odd or even pages only. One trap: the dialog counts physical pages, but the document’s own printed numbering can start after a cover and a contents page, so “page 5” in the footer may be physical page 7. Count with the thumbnail strip, not the footer.

6. Orientation. Portrait or landscape should come from the file, and modern dialogs read it automatically. Set it manually only when a landscape table inside a portrait document confuses the auto setting.

Two habits make all 6 settings cheap: read the preview pane before every print, because every problem below shows up there first, and when a long document is at stake, print 2 sheets as a test before the other 40. A test print costs 2 sheets; a wrong flip edge on the 48-page report costs 24.

When the dialog is enough, and when the file needs fixing first

A print dialog scales, selects and flips, but it cannot reorder pages, change what colour the file actually contains, or trim a scan’s margins. The split by symptom:

Symptom	Fix it in the dialog	Fix the file first
Edges cut off	Scale to fit (quick, shrinks everything)	Convert to your paper size with Resize
Prints tiny or with huge borders	Check “shrink oversized pages” is off	Crop wide scan margins with Crop
Backs upside down	Change the flip edge	Nothing; this one is pure dialog
Booklet pages out of order	Cannot be fixed here	Build a booklet file with Pages per sheet
One sheet per slide, paper everywhere	Some dialogs offer pages per sheet, no preview	Make a real n-up file with Pages per sheet
Grey print looks muddy or a shop bills it as colour	The checkbox converts blind	Convert the file with Grayscale and check it on screen
Only a few pages needed, repeatedly	A page range works once	Pull the pages into their own file with Extract pages
A form must print at exactly 100%	Actual size, always	Check nothing sits in the outer few millimetres

The rule of thumb: if the problem is where ink lands on one print, the dialog fixes it. If the problem is what the file contains, or the print will be repeated or shared, fix the file once and every future print inherits the fix.

Booklets and handouts: reorder the pages before the printer sees them

The jobs that save the most paper all come down to putting more than 1 PDF page on each sheet. Pages per sheet does this on your device: 2, 4, 6 or 9 pages per sheet for handouts, or booklet mode for something you fold and staple.

For handouts the maths is simple and the savings are not small. The 48-page report at 4 pages per sheet, printed double-sided, is 6 sheets of paper instead of 48. Pick 2 per sheet when people need to read comfortably, 4 for normal handouts, 6 for revision notes, and 9 only when the source pages are large text.

Booklets are the part nobody gets right by hand, because the pages must be reordered and paired so that a stack of duplex-printed sheets, folded down the middle, reads in order. Page 1 does not sit next to page 2; it shares a sheet with the last page. Here is the full layout for an 8-page booklet:

Up to 8 pages you could place these by hand. Past 8, the pairing (first with last, working inward, alternating sides) becomes too error-prone to do manually, and that is exactly what booklet mode automates: it reorders and pairs every page so the duplex print folds straight into a stapled booklet in reading order. Print the result double-sided, flip on the short edge, fold, and put 2 staples on the spine. The dedicated booklet guide walks through page counts that do not divide by 4 and where the blank pages land.

A4 and Letter: why edges get cut

The most common “my printer cuts the edges” complaint is not the printer. It is a US Letter file on A4 paper, or the reverse. The 2 sizes are close enough to look interchangeable and different enough to clip: Letter is wider and shorter, A4 is narrower and taller. Print one on the other’s paper at actual size and a strip of content disappears off the sides (Letter on A4) or the top and bottom (A4 on Letter). Choose “scale to fit” instead and nothing is lost, but everything shrinks a few percent, which is exactly what a form or a pattern cannot tolerate.

The one-time fix is to convert the file to the paper you actually print on.

Resize pagesA4↔Letter, N-up, booklet. Free, runs on your device.Open

Resize converts between A4, Letter, Legal, A3 and A5 on your device, scaling the content so the margins are designed rather than accidental. Do it once and the file prints clean on every printer that follows, no per-print scale fiddling. The dedicated Letter-on-A4 troubleshooter has the millimetre numbers and both directions of the trip.

Save ink and paper: grayscale, crop, extract

Three file fixes pay for themselves on every copy.

Print in grayscale from a grayscale file, not the checkbox. The driver’s grayscale option converts at print time with no preview, and different drivers convert differently.

Grayscale PDFBlack and white, text stays text. Free, runs on your device.Open

Grayscale recolours the file itself: text stays real text, sharp, selectable and searchable, and you can open the grey file and look at every page before paper, which is where you catch a pale yellow highlight fading to near-white. Gradients and patterns keep their colour, and the result says how many there were. A grayscale file also behaves consistently at a print shop or office copier, which matters because many detect colour objects in the file and bill colour rates even when the page looks grey. For a proof you hand around, the file beats the checkbox every time.

Crop scans before printing them. A scanned page is mostly margin: the scanner bed is bigger than the page, and phone scans include the table. Crop trims white margins or cuts by millimetres, across all pages at once, so “scale to fit” has content to fill the paper with instead of enlarging white space.

Print only what you need. For a one-off, the dialog’s page range field is the fastest tool there is. When the same pages get printed again, or someone else prints them, pull them into their own file with Extract pages; a 5-page file nobody can misprint beats a range someone has to remember. For reordering, rotating or deleting pages before any of this, see the guide to organising PDF pages, and if the file is also too heavy to send, make the PDF smaller first.

What these tools do not do

Honesty before you click: Resize and Pages per sheet, including booklet mode, embed each page into the new file as a vector drawing. Text stays perfectly sharp at any size, but links, form fields and comments are not carried over, and the result says so when the file had any. Keep the original for on-screen use; the converted file is your print copy.

Posters, 1 page split across many sheets to tape together, are not built yet. Adobe Acrobat Reader’s free poster mode does that job well and also runs on your device.

And the claim behind “on your device” is checkable, not marketing: run any tool on this page once, so its engine is in your browser, then turn Wi-Fi off, and it still works. The file never leaves your browser, which is why there is no upload bar to wait for and no server to trust with your lease, invoice or report.
