Speeding up the ocnPrint() function

I discovered that ocnPrint() can be very slow for larger data sets.
Searching the archives of this group turned up this old post, in which
the poster asks whether it's possible to speed up ocnPrint():

The solutions offered later in that thread may have worked out well,
but I found another one and thought I'd post it for the next person
who searches the archives.

I noticed that ocnPrint() is reasonably fast until the data gets above
a certain size. I don't know what that size is, but one does get a
warning if the printing exceeds 10000 points. To get around this, I
simply embedded the ocnPrint() statement in a for() loop, printing 1%
of the points each time through the loop. The index of the loop is
used to control the ?from and ?to switches. Obviously the 1% is
arbitrary, and can be increased or decreased for smaller or larger
numbers of points, respectively.

In my case, doing all the printing in a single statement took so long
that I just killed it after letting it run for several hours. The
looped version finished executing in under 5 minutes for ~20MB of
data.

Happy printing,
