Lexmark MX810
If your printer model supports two‑sided printing, then you can control whether print appears on one or two sides of the paper.
Notes:
You can print up to 16 consecutive pages of a multiple‑page document onto one side of a single sheet of paper by setting multiple page printing (N‑Up) for the print job.
Before printing or making multiple copies of a document:
Correctly set the paper type and size to avoid paper jams. For more information, see Avoiding jams.
