Writing CCITT Fax Group 4 TIF format from Photoshop

Dear Newsgroup,

I use Photoshop CS to edit photos primarily.
However, I prefer to use it as my editing tool for all images. As such I sometimes scan documents and then use Photoshop to correct blemishes, errors, dark spots, etc. with all the great tools Photoshop has. So far no problem.
When it comes to outputting the image, as it is a black and white document, JPG is lossy and ill-suited to this type of image. TIF is perfect, except in the uncompressed format takes up too much space. Photoshop CS reads all types of TIF files including raw (uncompressed), packbits, CCITT 1D, LZW compressed, CCITT Fax Group 3, CCITT Fax Group 4, JPEG and ZIP (deflate). However, it can only save to raw (uncompressed), LZW and ZIP (deflate).
The freeware program IrfanView can read and write to all formats! I would have expected my (more expensive) Photoshop to be able to do a bit better than that especially since Adobe currently holds the copyright to the TIFF specification (curently in Version 6).

My question is:
Can Photoshop CS wriste a TIF file in the CCITT Fax Group 4 format? If no, are there any plugins for it that may be able to do so?

Thanks in advance,

Xerxes

You don't know Adobe very well, do you.

It's trivial to use the tools at http://libtiff.org/ to recompress your TIFFs G4 (see, in particular, tiffcp). They've even been ported to Windoze.
