I have no idea what the problem is. Might it have something to do with paper
size? Does changing the size of your screen devices/win.print help?
I should mention that this is probably not a good way to print lattice graphs.
The settings for screen devices are not suitable for printing. I think there
are also more general issues with converting output of one device to another (I
don't understand all the details). In this situation, I would use
trellis.device(pdf, file = "foo.pdf")
for(i in 1:50){
print(histogram(~dbh|species.c, data=eval(parse(text=site.names.sort[i])),
breaks=c(0,seq(4,92,by=2)), main=site.names.sort[i], type="density"))
}
dev.off()
and then print the PDF file.
