How to Print Mixed Letter and Legal PDF Pages from iPhone in Adobe Acrobat
Question details
The user needs to print a PDF document containing both Letter and Legal page sizes from an iPhone without the app forcing all pages to print on Letter size.
- Product
- Adobe Acrobat
- Device & OS
- iPhone (iOS)
- Scenario
- Printing a mixed-size PDF document directly from a mobile device to a physical printer.
- Observed behavior
- Adobe Acrobat defaults to printing all pages as Letter size, failing to maintain the original mix of Letter and Legal page dimensions.
Ensure your printer supports both Letter and Legal paper sizes, has both types loaded into separate assigned trays, and has auto-tray selection enabled in its hardware settings.
Adjust Print Settings in Adobe Acrobat
Configure Acrobat's specific paper handling settings to recognize and utilize the PDF's native page sizes.
By default, mobile printing applications may attempt to scale all pages to fit the standard default paper size (usually Letter or A4). To maintain mixed sizes, you must explicitly instruct the app to pull paper based on each page's specific dimensions.
Launch the Adobe Acrobat app on your iPhone and open the PDF document that contains the mixed page sizes.
Tap the three-dot menu icon in the top right corner of the screen and select 'Print'.
Choose your AirPrint-enabled printer from the available list.
Scroll down to find the paper handling or page setup options. Toggle on 'Choose paper source by PDF page size' or set the paper size to 'Match document page size' if available.
Tap 'Print' in the upper right corner to send the document to your printer.
Print Using the iOS Files App
If Adobe Acrobat fails to preserve the mixed sizes, use the native iOS Files app as an alternative printing method.
Manage and Print PDFs Easily with WPS Office
WPS Office provides a seamless experience for viewing, editing, and printing PDFs on your mobile device. With robust print settings, you can easily ensure your documents maintain their original formatting and page sizes without complicated workarounds.
- 1. Open the PDF in WPS Office: Launch the WPS Office app on your iPhone and open your mixed-size PDF file.
- 2. Access the Print Menu: Tap the 'Tools' icon at the bottom left, navigate to the 'File' tab, and select 'Print'.
- 3. Configure Page Settings: Select your AirPrint printer, tap 'More Options', and ensure the scale is set to 'Actual Size' to preserve the original Letter and Legal dimensions.
- 4. Print the Document: Review the print preview to confirm the different page sizes are recognized, then tap 'Print' to send the document to your printer.
Frequently Asked Questions
Why does my iPhone print Legal pages on Letter paper by default?
Mobile printing defaults to 'Scale to Fit' on the most common paper size (Letter) to ensure content isn't cut off. To fix this, you must change the print setting to 'Actual Size' or 'Choose paper source by PDF page size' so the printer knows to pull from the Legal tray.
Does my printer automatically know which paper tray to use for mixed PDFs?
Yes, but only if the printer hardware supports auto-tray selection, has both Letter and Legal paper loaded in separate trays, and you have enabled the 'Match document page size' setting in your iPhone app.
What if I only have one paper tray in my printer?
If your printer only has a single tray, it cannot seamlessly print a mixed-size PDF. You will need to print all the Letter pages first, swap the paper in the tray to Legal, and then print the remaining Legal pages by manually entering those specific page ranges in the print menu.
Can I change paper size settings directly in the iOS AirPrint preview?
The native iOS AirPrint menu offers basic paper size selections, but advanced rules like 'Choose paper source by PDF page size' are typically managed within dedicated document apps (like Adobe Acrobat or WPS Office) before passing the job to AirPrint.
