Photoshop Printing Problems

[Richardgrant]

Hi,
I hope that somebody can help me. I run Photoshop CS3 and print on a Roland Versacamm VP540 large format printer. I have been using Photoshop for a while now with no problems and been printing with no hassles.
Recently I have been having problems with Photoshop. When I take photos to Photoshop and convert them to sepia and print them they come out with a serious green tint to them. When I convert photos to black & white and print them they come out with a serious purple tint on them. I know that it's not my printer because when I convert the photos using other applications and print them they come out perfect.
I have changed the colour settings on Photoshop to no avail. I have also tried to repair Photoshop in the installation process to no avail. I don't know what else I can do.
Please help.

What do you mean by that?
Did you try resetting your preferences file?

You can reset the preferences file manually:

Start the Photoshop while holding down Ctrl+Alt+Shift (Windows)
or Command+Option+Shift (Mac OS X).

Then, click Yes to the message, "Delete the Adobe Photoshop Settings file?"

Hi Steve,
Thanks for your response. If I reset the preference in the manner that you just suggested will I be able to continue as normal?

I won't have other problems if I delete the Adobe Photoshop settings file?

Any remapping or shortcut changes you may have made will go back to factory defaults.

Read this first.
Why is Photoshop acting strange? Some things just aren't working right.

You may also be able to locate and rename the file instead and see what happens.
