QM Query report prints with smaller font

I created a QM query and form which I want to print on standard 8.5 x 11 using a typical laser,
which is a >Laser Jet 600 M602< in my department.

I started with the following over-ride:

      OVRPRTF FILE(QPQXPRTF) PAGESIZE(66 84) LPI(6)   +
              CPI(10) OVRFLW(60) FONT(*CPI) PAGRTT(0) +
              USRDTA(SMP925C)


The first query manager form that printed, printed at 6 LPI x 10 CPI, which I need for readability.

As I changed column headings and page headings/footings, the report began printing at about 6 lpi x 15 cpi ?

(6 lpi >is< the lines per inch but the font is >narrower< than 15 cpi)

I then changed to a minimal over-ride:

       OVRPRTF FILE(QPQXPRTF) USRDTA(SMP925C)

That produced the same reduced-font report.

DSPF shows:

The Settlement Location value is from a six character field.

The last line in the DSPF snip is the default QM page footing, which I don't
know how to change/eliminate, but because it's the longest line, I wonder if
that causes the use of a smaller font ?

Any advice as to how to get my report to print at 10 CPI is most welcome - thanks all!
