We were able to duplicate the problem you describe and found that Palatino Bold
prints about one dot (not point size), or about 1/300 inch, smaller than the
Plain text Palatino. This is the result of the PostScript definition of the
font and is independent of application or driver.
This can be fixed only with a change to the ROM.
The only solution with this combination of PageMaker and the LaserWriter
Driver, is to use a different font family.
