can the canon pixma tr8620a print double sided automatically? the manual is confusing.

Yes, it has built-in 2-sided printing, which is also called duplex printing. You don't have to flip the pages manually.

1. On your computer, open the document you want to print and select Print.
2. Click on "Properties," "Preferences," or "Printer Settings" next to the printer name.
3. Look for a setting labeled "2-Sided Printing," "Duplex," or "Print on Both Sides." Select it. There might be options for binding on the long edge or short edge—choose based on your document.
4. Click OK and then Print. The printer will print one side, pull the paper back in, and print the other side automatically.

If that didn't work, ensure you're using standard weight paper (like 20 lb bond). Very thick or glossy paper might not feed correctly for duplexing.
