Writing printer friendly pdfs with ggplot2 and many (>25000) dots or lines

I am creating a lot of facet plots with ggplot2 and writing those into a multiple page pdf file. I added some sample data as an example.

reps <- 1000
df <- data.frame(id=rep(letters[1:25], each=reps),
                 group=rep(LETTERS[1:25], each=reps),
                 x=runif(reps*25),
                 y=runif(reps*25))
pdf('test.pdf', width=11.69, height=8.27)
for(i in seq(4)) {
  p <- ggplot(df, aes(x,y, group=group)) +
    geom_line() + geom_point() +
    facet_wrap(~ id)
  print(p)
}
dev.off()

To view the PDF it is really nice, but most of the time these big files with vector graphics kill my print jobs.

Is there a way to handle this properly? For example, creating PNG images and saving them in multipage PDFs? Or, am I the only one having problems printing such files?

I am aware that the PNG file might be bigger, but I guess the printer can handle it much better than a vector graphic.

The only solution I found so far is the following: https://helpx.adobe.com/acrobat/kb/quick-fix-print-pdf-image.html

I think this might be the best way since the creation of PDF is the same, you just switch to "print as image" in the advance printing dialog in Acrobat Reader...
