How to print horizontally on a HP Designjet 500 42 using Adobe Illustrator?

At work we have purchased a HP Designjet 500 42 poster printer. In Adobe Illustrator CS2, I am trying to print out a large web design company (http://www.************************) logo. The problem is; Illustrator is constantly forcing the printer to print the image out in the wrong orientation.

The logo is 20" wide, and 6" tall. Our printer uses a 42" roll. Illustrator keeping printing the image out such that the image is only using 6" of the total 42" width, and printing out 20" in length. Thus, wasting a lot of paper.

Is there any proper setup I am overlooking? I have tried every combination that comes to mind. Portrait vs landscape, rotate 90 degrees, entering custom paper sizes... Nothing comes out in a horizontal manor.

I will also mention that this has not been a constant issue in Adobe PS CS2. However my technique for that program, does not work for Illustrator.

Thanks in advance.

Can you not send it via PostScript to Photoshop, or import using Smart Layers (to maintain the vectored clarity of the artwork) and print via that? Or have you tried printing via Adobe Acrobat?

What is your page size? Are any elements off the page?

Also check your print setup. Are you using the Defined by Driver default under the Media area of the menu? (See my attached image for where I'm referring to.) I'm not sure if this is the problem, but try changing that to Custom and see if that helps.

If Illustrator still won't cooperate, you can try placing the Illustrator file into InDesign (if you have it -- I'm assuming you have one of the Adobe program suites) and print from there. Most people have less issues printing from InDesign than from Illustrator or Photoshop. Just be aware that there may be settings in some of the submenus that you will have to go through and change.

If this doesn't help, try posting screen shots of your page settings and print menu settings.
