In a printing control apparatus and method for performing printing by a printing
device based upon a print job, a password corresponding to a print job is entered
and print data with the accompanying password is generated and sent from a host
computer to a printer, where the print data is to be printed. The host computer
is capable of setting any information for the document name and user name associated
with the print job. When the printer receives and prints the print data to which
the password has been appended, the printer displays the user name and document
name associated with the print job and performs printing in response to entry of
the corresponding password by the user.
