Driver defined page sizes incorrectly scaled down from 10.2 on

I have created a PM / PDE driver combinations for my companies
narrow-width thermal printers. The PM component supports US Letter and
A4 paper sizes in addition to several custom paper sizes which it
defines (72mm wide and 104mm wide). Prior to 10.2, the custom paper
sizes printed very well.

Following the update release 10.2, printing using one of the PM defined
custom paper sizes (from some application), the print out is severely
scaled down.

This problem does not occur in all applications. For example: using MS
Word for X, printing is OK; but using TextEdit, the print is formatted
incorrectly.

Prior to 10.2, TextEdit worked fine as well.

The following knowledge base document has been prepared by Apple about
printing from TextEdit. It states that if you use TextEdit's menu
options to select the "Wrap to page" formatting, that the document's
text will be printed with the correct scaling. This is in fact the
case, and when I select "Wrap to page" my 72mm wide documents are
correctly printed.

The problem is though.

Some of my customer's applications (Point Of Sales) which previously
worked fine, now exhibit the same behavior as TextEdit does when using
the default "Wrap to screen" option. I can not require my customers to
rewrite their applications to "wrap to page".

Can somebody confirm if the "Wrap to page" and "Wrap to screen"
scenarios have changes at all since 10.2. And if they have, what I
might do within my PM driver module to correct the situation with out
requiring application side modifications.

Thank you.
