A powerpoint file which is 165 KB on the harddrive, increrase it's size to
3,3 MB when printing in color. Why?
 
Hi,

This seems strange but it is sort of normal. It has to spool to the printer
and this seems to take up some memory more than expected. Are you just
curious or are you having some sort of memory problem with this increase in
size?

Hello,

First, thank You for Your answer. The second, we really have a problem with
it. Users in my company creates powerpoint presentations and very often they
print them to the network printers. I've tested one presenation which has 1,5
MB on harddrive, and it has growen to 130MB when printing on the printer
connected to the local port (during the printing, I open printer's window and
in column size I can see how the amouynt of bytes grows and grows up to 130
MB). The same things happens even if I create a simple presentation with few
pictures - size on hard drive 129 KB but while printing 1,1 MB (ten times
bigger). You can imagine how long time it takes when such presentations need
to be printed over the network.

Kind regards

Brada
 
What type of printer do you use? Some printers may require the driver to send
completely rasterized data at the final print resolution. If the printer runs
at hig DPI settings, that can add up to a LOT of data. For example:

720dpi X 720dpi X 3 bytes per pixel = >1.5mb

That's per square *inch* of paper.

Changing the printer settings (ie, from Fine or Photo to a lower rez mode) might
help.

It might be worth changing the Print Processor setting from RAW to EMF to see if
that helps (Start, Settings, Printers, Properties page for your printer,
Advanced tab, Print Processor button.)

If switching to a PostScript printer is a possibility, that'd be worth
investigating as well; PowerPoint's PS output is quite inefficient and porky,
to say the least, but it's still likely to result in much smaller spool files
than what you're getting. If nothing else, you can test it easily; install a
driver for a PS printer, connect it to FILE instead of to a port and print one
of these same presentations. If the file's notably smaller, you have a possible
answer.
