It appears that I cannot print a line-only scatter plot with more than 2709
points in the series.

In a new workbook, I filled column A with "=row()" and column B with
"=sin(0.01*a1)". The chart appears correctly on the screen and in the print
preview, however printing to an HP printer (tried both laserjet 6 and deskjet
6100 series) or Adobe 9 PDF driver results in a chart with axes and legend
but no data.

If I change the range to 2709 points or less, the chart prints properly. If
I format the plot to include markers, it prints properly.

The system I'm using has both Excel 2003 and 2007 on it. I can save the
file as either a .xls or .xlsx file and open the file in Excel 2003. The
chart prints properly in this version of Excel.

I tried to reproduce the problem on a another computer, which did NOT have
Excel 2003 installed, and the problem does not appear. There are multiple
differences between the two systems however, so I cannot determine if this is
correlation or coincidence. I am very hesitant to uninstall Excel 2003 on my
main computer, since 2007 continues to present minor glitches like this one
that make life difficult.

Any comments/suggestions would be welcome.
