    <p><font face="Arial">Is it possible to ask Kinkos what scale they
        printed the base maps?  They don't have to actually reprint the
        maps, just go through the motions.  Open the PDF and look at the
        print options. As Andreas points out, the default is often "Fit"
        and there will be a "zoom" or "scale" percent displayed in the
        application (I use Foxit, and Adobe and both show this).  The
        page size parcel maps will have to be printed at this scale.  If
        they can guarantee that the print scale was 100%, then I would
        assume some other export discrepancy.</font><br>

      <p>Hi John,</p>
      <p>No - the PDF export does not distort the scale. But the
        printing of the PDF file might.</p>
      <p>It is absolutely important that - when printing the PDF - the
        setting "Actual size" or "Custom Scale at 100%" is used. All
        other options will change the scale.</p>
      <p>As far as I know, the default option when printing is "Fit",
        which will often shrink the content by some percentage - because
        some often "invisible" or white background might be present in
        the file that extends right to the edge of the page format.
        Acrobat then thinks that the content goes beyond the "printable
        area" of the printer and will scale down the whole file.</p>
      <p>Hope that clarifies this potential pit-fall when printing PDF
        files. It might well be a different issue than the one I
        describe, but this is a very common source of error that I know.</p>

                              massive) paper wall map on which to plot
                              and rethink its delivery driver
                              assignments. Both drivers and delivery
                              addresses are subject to change from week
                              to week but it's not a pizza delivery;
                              this is a regular run to supply people in
                              a bad way. So the plan was to print the
                              base map (roads and road names and county
                              boundaries only) and then print 8.5 x 11

                              That way, the base maps don't change but

                              solution, but not everyone is cut out for
                              that. It is what it is.) In order for this
                              to work, the parcel maps have to be the
