Final answer:
The duplexing assembly in a printer flips the paper and draws it back through the print mechanism to print on the other side, enabling automatic double-sided printing.
Step-by-step explanation:
If the printer is equipped with a duplexing assembly, then the rollers flip the paper and draw it back through the print mechanism to print on the other side. Duplexing is a feature in printers that allows for automatic double-sided printing, reducing the need for manual reinsertion of the paper to print on the other side.
In the context of laser printers, after the first side has been printed, the paper is flipped and re-introduced into the printer so that the reverse side can be printed. This process creates a two-sided printed document without requiring user intervention.
