AirPrint prints small, half page, or off-center — iPhone/iPad scaling, fit-to-page, paper size (A4 vs Letter), borderless
Technician
• What are you printing from — Safari, Mail, Files (PDF), Photos, Google Docs, or an app?
• Paper in the tray: Letter or A4? Photo 4×6? Borderless?
• Symptoms: prints tiny, half page, cropped, or off-center? Any “Borderless/Scale to Fit” toggle visible?
• Printer brand/model (HP/Canon/Epson/Brother) — some show extra AirPrint options.

• In Files or Safari, tap Share → Print, then pinch-out on the preview to open the full-page preview. Tap the thumbnail → look for **Paper size** and **Scale/Fill/Fit** (varies by printer).
• If your printer exposes it, set Paper = Letter or A4 to match the tray and pick Fit to Page (for PDFs/web) or Fill Page (for photos, may crop).
• If the options don’t appear, we’ll set the tray size on the printer and use the vendor app (HP Smart/Canon PRINT) for a proper scale to fit.
Technician
• On HP, pull the tray slightly, adjust guides, reinsert → the panel asks for **Paper size/type**. Set **Letter** (8.5×11) or **A4** to match what’s loaded, and choose **Plain** or **Photo** accordingly.
• On Canon/Epson, set **Paper Size** in the printer’s menu or web UI; some require confirming after every reload.
• Reprint from iPhone — AirPrint now receives the correct size via IPP, preventing half-page/tiny output.
Technician
• In Safari: Share → Options → PDF → **Save to Files**. Open that PDF in Files, then Share → Print → choose **Fit to Page**.
• For wide pages, use **Reader view** first (Aa → Show Reader) to remove sidebars; this avoids micro-scaling.
• If needed, print via HP Smart/Canon PRINT app — both expose explicit **Fit to Page / Scale** toggles that AirPrint sometimes hides.
Technician
• In the **Photos** app print sheet, pick the correct paper size (4×6/5×7/A4/Letter) if offered. Set **Borderless** only when using photo paper that matches the chosen size.
• Use **Fill Page** for edge-to-edge photos (may crop) or **Fit to Page** to avoid cropping (adds margins).
• Make sure the printer tray is registered as **Photo/Glossy** for 4×6; otherwise AirPrint leaves heavy margins or shrinks.
Technician
• HP Smart (App Store) → Print Documents/Photos → **Resize/Scale** → choose **Fit to Page** or a percentage (e.g., 100%).
• Canon PRINT / **Epson iPrint** offer similar scale, borderless, paper size controls and honor A4/Letter correctly.
• Update printer firmware and iOS; newer AirPrint builds improve default “Scale to Fit” behavior on some models.
Technician
• Keep printer **tray size** registered; re-confirm after reloading paper or switching A4↔Letter.
• For web pages, prefer **PDF via Files** or **Reader view** to avoid micro-scaling.
• Use vendor app presets for recurring tasks (Letter 100%, A4 Fit to Page, 4×6 Borderless).
• If prints start tiny again, power-cycle the printer and iPhone to refresh IPP capabilities.

Quick answer: the accepted fix
Accepted fix for AirPrint prints half page/tiny: set the printer tray’s paper size to match what’s loaded (A4/Letter/4×6), then in iOS open Share → Print and use the full preview to select **Fit to Page** (PDF/web) or **Fill Page** (photos). For stubborn apps, print the page to PDF in Files first or use the HP Smart/Canon PRINT app to force scaling.
Why AirPrint shrinks output (page size, margins, borderless & IPP)
AirPrint relies on the app’s document size and the printer’s IPP capabilities. If the printer reports **A4** while the job is **Letter**, iOS compensates with extra margins or scales down. Lack of **borderless** on plain paper can also force shrink-to-fit. Confirm tray registration, pick the correct paper in the preview (when available), or print via the vendor app to apply an explicit fit to page.
How to confirm full-size printing
Print a one-page PDF with a ruler graphic or form. Verify the measurement equals 100% on paper. If it’s off, recheck the tray size (A4 vs Letter), toggle **Fit to Page** in the preview, and ensure the printer isn’t forcing margins by disabling photo-only modes on plain paper. For photos, confirm Borderless is supported for the selected size.
AirPrint scaling — quick troubleshooting tips
Most “prints tiny/half page” issues are paper size mismatch or missing Fit to Page.
Quick path: register **tray paper size** on the printer → use iOS full preview to select **Fit to Page/Fill Page** → print long webpages as **PDF via Files** → use **HP Smart/Canon PRINT** for explicit scaling controls → update firmware and iOS if options are missing.

FAQ
Why does my iPhone/iPad print tiny or only half the page?
Usually a mismatch between document size and tray paper size (A4 vs Letter) or a missing **Fit to Page** setting. Register the tray size on the printer, then use the full iOS preview to select Fit/Fill appropriately.
How do I change paper size for AirPrint on iPhone/iPad?
Many AirPrint dialogs don’t expose paper size; set it on the printer’s control panel or web UI. Some vendor apps (HP Smart/Canon PRINT) let you choose paper and scaling before sending the job.
Best way to print long webpages without shrinking?
In Safari use Share → Options → PDF to create a paged PDF, then print from Files with **Fit to Page**. Reader view also helps remove sidebars that cause micro-scaling.
Photos crop or have big margins. What should I use?
Use **Borderless** only with matching photo paper (4×6/5×7). Choose **Fill Page** for edge-to-edge (may crop) or **Fit to Page** to avoid cropping (adds margins). Confirm the tray is registered as Photo/Glossy.
