HP 4250/4350 manual Orientation of paper for duplexing

Note the following guidelines:

●Before using the duplexer, ensure that the printer driver is set to recognize it. The procedure varies according to the operating system that you are using. For details, see Using the printer drivers. Look for the instructions in the column labeled "To change configuration settings."

●To print on both sides of paper, make the selection in your program or the printer driver. (See the printer driver online Help.)

●If you do not use the printer driver that came with the printer, you might need to change the duplex setting at the printer control panel, set DUPLEX=ON on the CONFIGURE DEVICE menu in the PRINTING submenu. Also on the PRINTING submenu, set DUPLEX BINDING to LONG EDGE or SHORT EDGE. (For more information, see Layout options for printing on both sides of paper.)

●The rear output bin must be closed to use the duplexer. Opening the rear output bin disables the duplexer.

Orientation of paper for duplexing

Several kinds of paper (such as letterhead, preprinted paper, prepunched paper, and paper with watermarks) require a specific orientation for duplex printing. The duplexer prints the second side of paper first. The proper orientation of the paper in the trays is shown below.
