The Black Ice printer drivers include a feature which
allows the driver to refuse any print jobs other than those coming from
the developer’s printing application. The restriction is made using a
password. The printer driver will print jobs only from the application
that “knows” the password. The password can be any string defined by the
developer.
The Black Ice printer driver will scan the document
name passed by the printing application for the presence of the
password, i.e the $MyPassword$ string. If the password string is present
in the document name, the files are generated, if the document name does
not contain the password, the print job will be aborted.
Developers can integrate this feature into their
applications which use the printer driver to ensure that no other
application, such as Word, Excel, etc. can print to the Black Ice
printer driver.
