laser printer, glossy stock, registration problem in draw

HI, I am hugely frustrated. I am running Win 2K pro, using a Xerox Phaser 7300 laser printer and Corel Draw 10, 12 or X3 printing on glossy stock and all colors except yellow are out of registration. I have tried different computers, fresh software installs with new documents (in case there was a corrupted file) and even a new printer - all with the same results. Corel blames Xerox, Xerox blames Corel and in the end my document is still out of registration. This does NOT happen on plain paper. And the same document prints fine on glossy stock on other printers.

I am hoping there is a setting someplace that I have missed that will resolve this. I ran all the above for 18 months with no problem. I even took a fresh computer that has Windows 2000 SP3 installed (in case the issue was SP4) with only Draw 10 and the Phaser printer installed - same thing.

ANY help will be greatly appreciated!
