The size of the PostScript header is less than 8K. Most header functions are
efficient and compact. This minimizes the overhead of print jobs that include
the header to just a few seconds.
Users who want to reduce printing times as much as possible should download the header to their printer using the Print Options dialog to make all the functions used be resident in the printer. With the header in place, printing times are reduced by about 10 seconds. However, for sending files to service bureaus, the header must be included in the print job and not downloaded previously.
