Odd. We sold 2400 dpi monochrome laser printers years ago. (They were 
very expensive then.) I have a half dozen 1200 dpi ones in-house now. To 
be honest, I usually use them at 600 dpi, because there's just not much 
point going higher on simple text output, which is what we primarily do. 
There are LED printers, which are often referred to as laser printers, 
which typically have had a 600 dpi resolution, and been cheaper than 
laser printers. I haven't really paid much attention to the market in 
recent years, as we no longer do much with the printing & publishing 
industry as we used to. (That used to be our bread and butter, but has 
largely evaporated over the years.) So, I don't really know what's 
current, but higher than 600 dpi resolutions were common back in 2000. 
They were in the business class and publishing class market.
