HP Color LaserJet 4650 Software Reference Guide

The HP Color LaserJet 4650 printer supports smart duplexing. The smart duplexing feature
increases printing performance by not sending one-page print jobs or single-sided pages of a
duplexed print job through the duplexing unit even when the duplexing feature has been enabled
in the driver.
All media types support the smart duplexing feature, except for media types that cannot be
printed on both sides, such as labels, and the following media types:
Prepunched
Preprinted
Letterhead
When the media type is set to Unspecified, the smart duplexing feature is disabled.
Manually printing on both sides
To make the Print on Both Sides (Manually) check box available in the document options,
select the Allow Manual Duplexing check box on the Configure tab in the Properties print-
driver tabs. See Paper Handling Options in this chapter.
Manually printing on the second side of a page is available when you are using the HP
Traditional PCL 6 Driver or the HP Traditional PCL 5c Driver. The HP Traditional Postscript 3
Emulation Driver does not support the manual duplexing feature. If a duplexing unit is
installed and manual duplexing is enabled in the driver, the printer automatically duplexes
media types that are supported by automatic duplexing (Letter, A4, Legal, 8.5 x 13, and
Executive (JIS) only), and forces manual printing on both sides for media types that are not
supported.
Plain
Preprinted
Letterhead
Prepunched
Bond
Recycled
Colored
Rough
Heavy and Cardstock media can be manually printed on the second side, but there is no
change to the print mode. Transparencies and labels should not be manually printed on the
second side.
