Despite upgraging the printer memory, if the number of print copies is less
than 20 , the laser churns out the copies one after the other. However if
when say 100 print copies is requested, the printer slows between copies as I
understand the buffer is full. How can the number of copies be automated so
that up to 20 print copies per 'batch' is sent and when done the next 'batch'
of up to 20 is sent until the total number print copies is done.
