PRINTING ON BOTH SIDES OF THE PAGE

HP LaserJet printers that have the letter D in their model name (D, DT, DN, or  DTN) all have built-in automatic duplexing capability. These printers support 8.5 x 11, A4, 8.5 x13 and legal paper sizes.

Note: Do not print on both sides of labels, transparencies, or vellum. You may damage the printer.

Below you will find procedures for checking the printer driver abilities for Windows XP and Macintosh OS X. You will also find general printing instructions for duplexing a document.

Printing Double-Sided Documents

Even if a printer has duplex installed, you will not be able to initiate duplex printing using the Print button on an application toolbar.*  Instead, you must open the Print dialog box and explicitly select duplexing, as follows:

1. Open a document you wish to print double-sided.  Click on the File Menu and select Print. The Print dialog box appears.
   
   
2. Click on the Properties or the Preferences button (programs vary in language). The Document Properties dialog box appears with the Layout Tab selected .
   
   
   
   
   
3. In the Print on Both Sides area, select Flip on Long Edge.   Note if you do nothing else your document will be bound on the long left edge portrait like the illustration.
   
   Note:  If the Print on Both Sides is not available to you return to the top of these instructions you as need to tell the printer driver that duplexing is available.
   
   
4. Selecting Flip on Short Edge will display short-edge portrait duplexing. 
   
   
5. Click on the OK button to return to the Application's Print dialog box.
   
   
6. You are now ready to select the page range or change the number of copies before sending the document to the Printer.
   
   Note: Duplex settings will hold until you close the application or change the Print Properties and the Layout Options back to None for printing on both sides.

*NOTE: If you would like your default setting to be double-sided printing, you must install a specific duplex driver for your printer. Click on the link below to go to the Hewlett-Packard website, where you can download duplex drivers for HP printers:

Printing a Duplex Document

When a printer has duplex installed you are able to print duplex from all your programs.  Word, Excel, GroupWise, Adobe Reader .....etc.   However, you can not use the Print Icon from the toolbar as this is a short cut to print the whole document without opening the Print dialog box which gives you the options to select duplexing.

1. Open a document you wish to print in the duplex manner.  Click the File Menu and select Print.
   
   
2. Enter the number of copies or pages to print now before you select duplexing.
   
   
3. From the Copies and Pages drop-down menu, select Layout.
   
   
   
   
4. From the Two-Sided area, select either Long-edged binding or Short-edged binding.  Note that the sample will change to show  how the document will print.
   
   
5. Click the Print button to send the document to the printer.

Duplexing on Letterhead or Preprinted Forms

If you don't know how to place letterhead stationery or preprinted forms in the paper tray of your printer so they will print correctly, pull down the printer's manual feed tray or pull out the paper tray and check the diagrams showing how paper should be positioned in the tray.
