Your printers alignment is out that is why it prints only in one direction.

Bidirectional Printing - A means of printing by a computer printer which prints one line from left to right, then the following line from right to left. Such printing is faster than printing in one direction only, as there is no need to wait for the carriage or other imaging mechanism to return to the left margin before starting a line.
how to enable bi-directional printing.here's how:
  1. -click on start
  2. -click on printers and faxes (control panel->printers and faxes)
  3. -right-click on Dell Photo All in One Printer 964 All-In-One icon
  4. - click on properties
  5. -click on ports tab
  6. -down at the bottom there's a small box before bi-directional support
  7. -tick the box to enable it then click apply,ok
  8. -try printing again

note: in vista , printers and faxes is printers.in win 7 ,it's devices and printers.
and properties in win 7 is printer properties


Problems with Printing Special Size Forms

you have to chk the setting on the print setup.

My OKI 591 is only printing going one direction, not backwards and forwards like before so it's very very slow. Is there a setting that causes this? Thank you

Usually when this printer prints in HIGH QUALITY, it will only print one way, to avoid misalignment issues between the one pass one way and the next pass coming from the opposite direction.

If I am right, lowering the quality of your print to "normal" or "draft" should give you back the "2-way printing"

Printing does not conform to the spacing of the pages on A3 continuous stationery

kindly set the page lenght and the font size and mode in printer setup by going in to printer menu by pressing the pause and menu button.


Printer keeps printing over the =same line, paper is not moving

Theirs a small gear in the gear train on the left hand side that turns the paper roller(Platen).
It has lost a couple of teeth. Has the paper is no longer feeding the print head simply keeps printing on the same place.
You need a service repair.

How do I set the MX700 for bidirectional printing? It sounds like it is only printing in one direction.

Bidirections can have two meanings with printers.

One is where the computer communicates with the printer and the printer communicates with the PC

The other is usually found on tractor feed or other form feed printers where the printer can reverse the direction the paper travels. This is not seen as often as it once was.

Yours is an AIO inkjet printer and these do not generally do paper feed direction changes.

Make sure the option for bidirectional printing is set correctly.

Try it both ways

Make sure you are not printing too far to the left or the right - the print head can hit the end of its run and lose its place.

What it means Enable Bidirectional Communication caution spam number below

To enable bi directional printing:
Open Printers and Faxes in control Panel
Right Click on the Printers Icon
In the Properties dialog box select the PORTS tab
Near the bottom there is a check box to enable Bi-directional printing
Make sure it is checked
Click OK to exit the dialog box

Printing trouble

I think your alignment is out you need to get the printer serviced and aligned.


The types of printers that you have actually should be assigned to a free port, you cant setup 2 printers on the same port. check at the back of the printer the physical attachment of two printers the OKI and the Epson, if Oki is set to lpt1 then assign port from printer properties for oki to lpt1, and lpt2 on epson. 1 printer- 1 port, so by then check if the box for enable bidirectional support is check, remove the check mark from the box by clicking on it then hit apply then try printing a test page then try printing from application.
