Tel me the processedure of duplex printing - HP LaserJet 4250dtn Printer

To print duplex on a Mac:
1. After finishing your document, go to File >> Print. You will see something like the following:
2. Make sure that Layout is selected: 3. Under two-sided, make sure than Long-edged binding (or something similar) is turned on.

This will allow you to print duplex (two sided) on the Mac.

A duplex unit allows you to automatically print double sided jobs. It sounds like a duplex unit is an option on your printer. If it is asking you to install a duplex unit, it is either configured for duplex printing i.e in your printer setup, duplex printing is enabled or, your driver has two sided printing enabled as its default.
Hope this helps.

You have to print the first side then take those prints and put them back into the paper tray to print the second side (Manual Duplex). If this were a DN model it would have built in automatic duplexing and you cound select "duplex printing" from your print setup screen and the printer would print both sides automatically.

Hi,

In your printer model duplex printing is not supported. But it can be achieved using the manual duplex printing option. In the printer properties select the type of duplex printing you want to take and click on print. Once the printing got over on one side of the papers, then you will be prompted to turn the whole printed paper bundle and keep in the tray again and continue the printing. Now by this way duplex printing is done in your printer model.

I hope this is useful to you.
Please rate the solution provided.
Thanks

Hello
See if you have selected weight paper from the tray in the duplex mode.
Weight paper is selected in duplex mode only from the bypass.
So you check that the paper in the tray 1 or tray 2 must be plain paper and in duplex mode it can print normally.

Only if you print the first side then place the paper back into the printer to do the second side. Also referred to as manual duplexing. This printer has no automatic duplexing option.
Also keep in mind that the percentage of duplex prints you do should be very low as this printer has no method of cleaning the fusing unit as most printers do that are made for duplexing. The industry standard is 2% or less should be duplexed.

The MP610 does support duplex printing.

Duplex Printing

The duplex printing function allows you to print data on both sides of a sheet of paper.
The procedure for performing duplex printing is as follows:
Performing automatic duplex printing
You can perform the duplex printing without having to turn over the paper.
1. Open the printer driver setup window, check the Duplex Printing check box, and confirm that Automatic is checked.

2. Select Normal-size Printing (or Fit-to-Page Printing, Scaled Printing or Page Layout Printing) from the Page Layout list.
3. When printing a document that has small margins, click Print Area Setup... and set the print area.
When you perform duplex printing, the print area of the document becomes slightly narrower than usual and the document may not fit on one page.

To print without reducing the page:
Select Use normal-size printing.
To reduce the page slightly during printing:
Select Use reduced printing.
4. Specify Staple Side.
The printer analyzes the Orientation and Page Layout settings, and automatically selects the best staple position. Check the Staple Side setting. If you want to change the setting, select another value from the list.
5. If necessary, click Specify Margin... and set the Margin width.
6. Click OK.
Duplex printing will be started.

Performing duplex printing manually
You can perform the duplex printing manually.
1. Check the Duplex Printing check box and uncheck the Automatic check box on the Page Setup tab.

2. Select Normal-size Printing (or Fit-to-Page Printing, Scaled Printing or Page Layout Printing) from the Page Layout list.
3. Specify Staple Side.
The printer analyzes the Orientation and Page Layout settings, and automatically selects the best staple position. Check the Staple Side setting. If you want to change the setting, select another value from the list.
4. If necessary, click Specify Margin... and set the Margin width.
5. Click OK.
If a media type other than Photo Paper Plus Double Sided is selected for Media Type on the Main tab:
When you execute print, the document will be printed on one side of a sheet of paper. When printing is complete, reload paper according to the displayed message and then click OK. The document will be printed on the opposite side.
If Photo Paper Plus Double Sided is selected for Media Type on the Main tab:
When you execute print, the document will be printed front and back alternately for one sheet at a time. Load the paper according to the displayed messages.
Note Duplex Printing is unavailable when:
- A media type other than Plain Paper, Photo Paper Plus Double Sided or Hagaki is selected from the Media Type list.
- Poster Printing is selected from the Page Layout list.
When Booklet Printing is selected from the Page Layout list, Duplex Printing and Staple Side appear grayed out and are unavailable.
After printing the front page, there is an ink drying wait time before starting to print the back page (Operation stops temporarily). Do not touch the paper during the time. You can change the Ink Drying Wait Time at Custom Settings on the Maintenance tab of the printer driver.
When you perform the automatic duplex printing for Hagaki, print an address first and then print your message.
Tip If you select Photo Paper Plus Double Sided for Media Type on the Main tab, the Duplex Printing check box on the Page Setup tab is not checked automatically. To perform duplex printing, check the Duplex Printing check box.
If the Media Type dialog box appears when performing borderless printing during duplex printing, select Plain Paper or Photo Paper Plus Double Sided.
When performing the automatic duplex printing, do not use any plain paper smaller than A5. Also, do not select any type of paper other than Plain Paper, Photo Paper Plus Double Sided or Hagaki at Media Type.
Photo Paper Plus Double Sided is highly recommended for printing photographs on both sides of a page.
If the back side of the paper becomes smudged during duplex printing, perform Bottom Plate Cleaning in the Maintenance tab.

Have you told the print driver that you have a duplex fitted, also is the paper set as plain as any thick setting will cancel out the duplex function.

Some printers automatically print on both sides of a page (automatic duplex printing); other printers allow you to manually reinsert pages to print the second side (manual duplex printing); and some printers do not support duplex printing at all. To find out whether your printer supports duplex printing, you can check the printer manual, contact the printer manufacturer, or check the printer's properties by clicking Properties in the Print dialog box.
To find out whether your printer supports duplex printingThe options in the Print dialog box can vary depending on your printer options and configuration.
You can use the following clues to determine whether a specific printer supports duplex printing:

• Check your printer manual or consult your printer manufacturer.
• Click the tabs in the Print dialog box and review the options. If options such as print on both sides of the paper, duplex printing, or two-sided printing appear on any of the tabs, the printer probably supports automatic duplex printing.

Notes

• If you are printing to a combination copy machine and printer, and the copy machine supports two-sided copying, it probably supports automatic duplex printing.
• If you have more than one printer installed, it's possible that one printer supports duplex printing and another printer does not.

To manually set up a printer to print to both sides of a sheet of paperWith some printers, you can use the Manual duplex check box under Printer in the Print dialog box. Word will print all of the pages that appear on one side of the paper and then prompt you to turn the stack over and feed the pages into the printer again.
You can also use the following procedure to set up your printer for manual duplex printing:

1. On the File menu, click Print.
2. In the lower-left corner of the Print dialog box, in the Print box, click Odd pages.
3. Click OK.
4. After the odd pages are printed, flip the stack of pages over, and then in the Print dialog box, click Even pages.
5. Click OK.

Note Depending on the printer model, you might have to turn and reorder the pages to print the other side of the stack.
