Abstract

The present invention provides a printer responsive to commands from printer driver software. The printer driver software is characterized by being responsive to two types of input data. One of the types includes text data, and the other of the types includes watermark data. The two types of data are separately applied to printer driver software, rather than integrated together prior to application to the printer driver software.

Claims

1. A printer responsive to commands from printer driver software, the printer driver software being characterized by being responsive to two types of input data, one of said types comprising text data, the other of said types comprising watermark data, the two types being separately applied to the printer driver software, rather than integrated together prior to application to the printer driver software.

2. A printer according to claim 1 wherein the printer driver formats the watermark data to be printed as a subtle background tint.

3. A printer according to claim 1 wherein the printer driver formats the watermark data to be printed as a modulation of the text data.

4. A printer according to claim 1 wherein the printer driver is arranged to control ejection of ink droplet from the printer onto a substrate at a first print density for the text data and at a relatively finer density for the watermark data.
