Set your printer to Duplex (Long-Edge Binding), enable Mirror Margins in Word (1.5" left, 1" others), and print a test page on plain paper. If page numbers misalign, manually adjust in the footer and reprint.
What messes up double-sided printing?
Double-sided printing fails when the printer flips pages the wrong way—either over the long edge (standard for books) or the short edge. Without proper binding margins, text can vanish into the gutter or land on the wrong side. Microsoft’s own support docs confirm mirror margins are non-negotiable for anything meant to be bound.
Here’s exactly how to print your thesis double-sided
These steps work in Microsoft Word 2024+. I’ve added Google Docs and macOS tweaks below.
- Mirror your margins first
- Open your thesis document.
- Head to Layout → Margins → Custom Margins.
- In the “Margins” tab, set Left: 1.5", Top: 1", Bottom: 1", Right: 1".
- Under “Multiple pages,” pick Mirror margins.
- Click OK. Now your layout looks like a real book.
- Turn on duplex printing
- Go to File → Print.
- Pick your duplex-capable printer (I use an HP OfficeJet Pro 9025e).
- Hit Printer Properties or Preferences.
- Choose Long-edge binding (Standard) under “Duplex” or “Two-sided.”
- Set paper type to Bond or Premium (100–120 g/m²).
- Print a single test page
- Print one page on scrap paper first.
- Check text hugs the binding edge (left margin).
- Confirm page numbers sit in the outer bottom corner.
Google Docs users (2026 web version)
- Open your document in Google Docs.
- Hit File → Print.
- In the print box, enable Two-sided → Long-edge binding.
- Under “Margins,” set Inside: 1.5", Outside: 1".
- Print to PDF first, then send the PDF to your printer.
macOS users (Word 2025 or Pages)
- Open your document in Word or Pages.
- Go to File → Page Setup.
- Set margins to 1.5" left, 1" others.
- Hit File → Print.
- Click Show Details, then pick Two-Sided → Long-Edge Binding.
- Print.
