Cups on my system at times is extremely slow finding the printer.
my default printer hpd is an HP M402 printer. But if I run say lpstat -a
it takes 25 sec before it lists the printere. It will do the same at
times when i try to print something. I cannot tell when it behaves and
when not. 
In /var/log/cups/error I getthe following lines

-------------
