How to Print Mixed Letter and Legal PDF Pages on a Mac
Question details
The user needs to print a single PDF document containing both Letter-size and Legal-size pages using a dual-tray printer on a Mac.

- Product
- PDF Reader/Editor (e.g., Adobe Acrobat, Mac Preview)
- Device & OS
- MacBook Air (macOS)
- Scenario
- Printing a mixed-size PDF document to a dual-tray printer.
- Observed behavior
- The goal is to automatically pull Letter paper from one tray and Legal paper from another tray based on the PDF page sizes.
Ensure your dual-tray printer is properly loaded with both Letter-size and Legal-size paper, and that the macOS printer drivers are up to date.
Configure Adobe Acrobat for Mixed Page Sizes
Use the built-in 'Choose paper source by PDF page size' feature in Adobe Acrobat to automatically select the correct tray.
Adobe Acrobat includes a dedicated print setting designed specifically for handling documents with varying page sizes. This ensures the software communicates the exact dimensions of each page to your printer.
Launch Adobe Acrobat on your Mac and open the PDF containing the mixed Letter and Legal pages.
Click 'File' in the top menu bar and select 'Print', or press Command + P.
In the Print dialog box, check the option that says 'Choose paper source by PDF page size' under the Page Sizing & Handling section.
Click the 'Printer...' button at the bottom of the dialog. Ensure your specific printer is selected and verify that auto-tray selection is enabled in your printer's specific features menu.
Click 'Print' to send the job to your dual-tray printer. The printer will automatically pull from the Letter or Legal tray depending on each page's dimensions.

Print Mixed Sizes using Mac Preview
If you don't have Adobe Acrobat, you can adjust settings in the default Mac Preview app, though it requires specific printer driver support.
Handle Mixed-Size PDFs Easily with WPS Office
WPS Office provides a comprehensive built-in PDF reader and editor. You can easily view, manage, and print PDFs with varying page sizes directly from your Mac without needing expensive software.
- 1. Install WPS Office: Download and install WPS Office for Mac from the official website.
- 2. Open the PDF: Launch WPS Office, select the PDF tab, and open your mixed-size document.
- 3. Access Print Settings: Click 'Print' (Command + P) and locate the page sizing and handling section to match your printer's tray settings.

Frequently Asked Questions
Why is my printer only pulling Letter-size paper for the whole PDF?
This usually happens if 'Choose paper source by PDF page size' is unchecked in your print dialog, or if the printer driver is forcing a default paper size. Ensure auto-tray selection is enabled and that the printer physically registers the Legal paper in its tray.
Does the Mac Preview app support printing mixed page sizes automatically?
Mac Preview's ability to print mixed sizes depends entirely on your specific printer's driver. It lacks the dedicated 'choose by PDF size' checkbox found in Acrobat, so relying on the driver's 'Auto Select' tray feature is required.
How do I load my dual-tray printer for mixed-size printing?
Typically, you load standard Letter paper (8.5 x 11 inches) into Tray 1 and Legal paper (8.5 x 14 inches) into Tray 2. Consult your printer's manual and configure the tray settings on the printer's physical control panel so it recognizes the loaded paper sizes.
Can I print mixed Letter and Legal sizes on a single-tray printer?
On a single-tray printer, you cannot print them simultaneously in one go without manual intervention. You would need to print the Letter pages first, swap the paper in the tray to Legal size, and then print the remaining Legal pages.
