HP LaserJet M1005 Multifunction Printer series - Manual (Page 127)

Toner consumption
EconoMode uses significantly less toner, which might extend the life of the print cartridge.
Paper use
The device manual duplex features (two-sided printing) (see Printing on both sides on page 33 for
Windows and Printing on both sides (Macintosh) on page 37 for Macintosh) and N-up printing capability
(multiple pages printed on one sheet) (see Printing multiple pages on one sheet of paper on page 32
for Windows and Printing multiple pages on one sheet of paper (Macintosh) on page 36 for Macintosh)
can reduce paper usage and the resulting demands on natural resources.
Plastics
Plastic parts over 25 grams are marked according to international standards that enhance the ability to
identify plastics for recycling purposes at the end of the device's life.
