Bad printer drivers

I bought an HP C6380 all-in-one printer the other day and just noticed something weird. The time it takes before it starts printing is exponential to the number of copies I want to make. How stupid is that? If I want to print the same page 20 times it shouldn’t have to take 20 times longer for it to figure out what to do before printing, should it? Just calculate everything once and use the same calculation 20 times. There is obsiously something I don’t know about writing printer drivers, or the drivers are just bad. Scary.
