Printing on both sides of paper is called duplex printing. Most printers offer the option of automatically printing on both sides of a sheet of paper (automatic duplex printing). Other printers provide instructions so that you can manually reinsert pages to print the second side (manual duplex printing).

Why can't I print on both sides?

If you don't see a Print on Both Sides pane, then your selected printer doesn't support duplex printing. Or, the feature is turned off (see Verify that printer features are turned on). Click OK, and then click OK again to print.

Is it better to print double-sided or single sided?

Single sided printing also provides the most economical printing option. On the other hand, duplex printing is particularly useful for situations that require cards to contain more than just a name and photograph.
