How to print TIF always(!) rotated?

[Peter2]

I have

- TIFF, b/w, 400 dpi
- made with a scanner
- always in "landscape-reading" format (That means that I can read the texts on the scans normally from left to right. Sometimes the paper is portrait DIN A4 etc., but the display on the screen is correct).
- sometimes really huge format (900 height x 4000 mm length, landscape)

I have to print them on a plotter with paperwidth 300-900mm and paperlength endless.
In this sense the printed paper is always "portrait-paper" because the length (the raper-roll, max. 15000 mm) is greater then the width (from left to right, max. 914 mm).

To print a "landscape tif" (from left to right) to a "portrait-paper roll" (from bottom to top) I have to rotate the print. This is no problem with "auto-roate" in print menu.

But:
Depending on the software the rotation is sometimes +90°, sometimes -90°.
To feed my plotter and my plotsoftware with uniform plot-data (for making correct paper-finishing) from different applications.

And this is why ...
I need to rotate every file (every picture) 90° clockwise - not only the large ones, also the small ones.
Is it possible to reach this?
