The number of pages of a print job received at printer ( 10 ) is determined ( 256 ). If the number of pages is low, printing is conducted at intermediate speed ( 262 ). If the number of pages is higher, printing is conducted at high speed ( 254 ). If the number of pages is not known, a default is selected ( 260 ). The default often will be to print at intermediate speed because most jobs are short. If high speed printing is in progress when a job is received, the next job is printed at high speed ( 254 ). Alternatively, a predetermined number of the first pages of a job may be printed at intermediate speed.
