HP traditional drivers Automatically printing on both sides The duplexing unit in the product prints on two sides of a sheet when the Print on Both Sides option is specified in the print job. The HP LaserJet 4345x mfp, HP LaserJet 4345xs mfp, and HP LaserJet 4345xm mfp models come with a duplexing unit installed. The HP LaserJet 4345mfp 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 transparancies, and the following media types: ■ Prepunched ■ Preprinted ■ Letterhead When the media type is set to Unspecified, the smart duplexing feature is disabled. To achieve the best print quality when printing on the second side of the page, the product needs to make adjustments to its print modes. When you select a media type, you are, in effect, instructing the product to use a group of settings, such as fuser temperature and print speed, to produce the best possible quality. This group of settings is known as a mode or print mode, and a different print mode is used with each media type. Print-mode adjustments are automatic when the duplexing unit is used. Flip Pages Up The Flip Pages Up check box, which is available only when Print on Both Sides is selected, is used to specify the duplex-binding option. By default, the Flip Pages Up check box is not available. The following table demonstrates the results of selecting this box, depending on the media orientation that is selected on the Basics tab. Table 3-2 Page orientation Orientation (Basics tab) Portrait Landscape Flip Pages Up selected Short-edge binding Long-edge binding Flip Pages Up not selected Long-edge binding Short-edge binding When Print on Both Sides is selected, the document preview image changes to show a spiral binding along either the left edge or the top edge of the page. In addition, a folded-over corner appears in the lower-right portion of the preview image, indicating that printing occurs on the back side. An arrow on the folded-over corner points in the direction that the pages would be flipped if they were bound together. Short-side binding is for print jobs with pages that read by flipping over like the pages of a note pad. Long-side binding is for print jobs with pages that read by turning like the pages of a book. Booklet Printing The Booklet Printing drop-down menu is visible when Print on Both Sides is selected and a supported media size is selected in the Size is: drop-down menu on the Paper tab. The Booklet Printing drop-down menu offers choices that are based on the current media size. The default HP traditional PCL 6 and HP traditional PCL 5 driver features 101
