Thank you for taking time to answer.

I upgraded to 8.70.
with '-sDevice=pswrite' the output page size is correct A4 (8.26 x 11.69 inches) -- characters and page size are OK.
using '-sDevice=ps2write' the output 8.50 x 11.00 inches -- charachters ar ok, but the document doesnt fit

As I know the 842x592 points are correct for A4 papersize.  

It seems that the code i using (device=pswrite) is correctly convert the pdf to ps (checked using adobe distiller).
When Hylafax conerts this PS to Tiff, things go wrong.

How to get ps2write working with the correct papersize? 
I hope the output of ps2write is going to give better results when converted to tiff.
