Question details
The user is experiencing unpredictable page rotation when printing a PDF using the 'Choose paper source by PDF page size' option.

- Product
- Device & OS
- not provided
- Scenario
- Printing a PDF document that contains varying page sizes or using specific paper source matching settings.
- Observed behavior
- Pages rotate unpredictably because the printer driver or PDF software automatically adjusts the orientation to match the selected paper size.
Ensure your printer drivers are up to date and verify the actual dimensions of the pages in your PDF document before adjusting print settings.
Disable Automatic Orientation in Printer Settings
Prevent the printer driver from automatically rotating pages by manually setting a fixed orientation in the printer properties.
When 'Choose paper source by PDF page size' is enabled, the printer driver often attempts to be helpful by automatically rotating the page to fit the physical paper loaded in the tray. Disabling this auto-rotation in the driver properties usually resolves the issue.
Open your PDF file and press Ctrl+P (Windows) or Cmd+P (Mac) to bring up the print dialog box.
Select your printer from the drop-down menu and click on the 'Properties' or 'Preferences' button next to it.
Navigate to the 'Layout', 'Finishing', or 'Page Setup' tab within the printer properties window.
Find settings related to 'Auto-Rotate', 'Auto Portrait/Landscape', or 'Page Orientation'. Turn off the automatic setting and manually select either 'Portrait' or 'Landscape' based on your document.
Click 'OK' to save the printer properties, then click 'Print' to output your document.

Uncheck Auto-Rotate in the PDF Print Dialog
Turn off the software's built-in auto-rotation feature to maintain the original document orientation.

Frequently Asked Questions
Why does 'Choose paper source by PDF page size' cause rotation?
This option tells the printer to match the physical paper size to the document's digital dimensions. If the printer's tray is loaded differently (e.g., landscape instead of portrait), the software or printer driver may automatically rotate the page to make it fit the paper layout.
How can I check the actual page size of my PDF before printing?
Open your PDF, go to 'File' > 'Properties' (or right-click and select Document Properties). Look under the 'Description' or 'General' tab to find the exact page size dimensions.
Does this rotation issue happen with all printers?
No, it typically depends on how a specific printer's driver handles automatic orientation and paper source mapping. Updating the printer driver or using a different PDF reader can sometimes resolve conflicting settings.
Can I force all pages to print in one orientation regardless of size?
Yes. In the print dialog, uncheck 'Choose paper source by PDF page size' and manually select either 'Portrait' or 'Landscape' to force a uniform orientation across the entire document.
