Sending graphical output to a printer

Dear all,

Does anyone know how to send graphical output to a printer using R for Windows
version 1.6.2. For example if I do

plot(x,y) # Sends output to the graphics window

which command will let me print this graph?

The reason I need to do this is to automatically print out a lot of graphs
without having to select Print from the graphics window at each one.

Thanks in advance for your help.

Paul.
