Print macro using Microsoft Office Document Image Writer

I am using Word 2003 on Windows XP Pro.

I need to set up a print macro that prints a template to Microsoft Office Document Image Writer.

I got the macro set up to engage the printer but not sure how to proceed on the following steps:

1. I need Microsoft Office Document Image Writer to open

2. then you have to select one of 6 file names

3. save as one of those names then it is saved as a .tiff image

4. then need the printer to reset back to default printer for regular printing.

I have step one down but unsure how to proceed on the next three steps.
Any suggestion on the next steps or where I could find documentation to assist me would be appreciated.
