As Stefan says, if you use a raster format like BMP, TIFF, or PNG, use
it at the resolution of your printer.

That can make a really huge file if your board is very big. 4x5 inches
at 1200dpi is 20 x 1,440,000 = 2.88 x 10^10 or about 30 Meg (assuming
greyscale). If your laser printer does not have 30 Meg, it won't print.

Someone who knows tell me- is the file converted to BW by the driver
or the printer itself?

Vector formats are superior to raster, if you can use them.
