I have seen your code and I don't understand this lines :

if (phW>phoX+PageWidth)

phW = phoX+PageWidth;

I think this condition is always true and create a false result when you

calculate :

TmpRM = MulDiv(RVPrint1->RightMarginMM, 5*lpx, 127)-

(phW-(phoX+PageWidth));

because the right margin offset calculate is 0.

i.e :

In my case, phw = 4960, phox = 100 and PageWidth = 4760.

The "if" is true and phw is affected to 4860.

The right margin offset is calcultate to 0 (4860-(100+4760)) and not 100

(4960-(100+4760)).

So : Right margin = RightMarginMM + Right margin offset.

I suppose the problem as same for Bottom margin Offset.
