UNIX Printing Overview<br />

Motif and character-based UNIX operating systems do not have <strong>the</strong>ir own standard<br />

interface <strong>to</strong> printers as does Microsoft Windows. Individual applications are<br />

responsible for sending <strong>the</strong>ir output in a streamed file <strong>to</strong> <strong>the</strong> printer and adhering <strong>to</strong><br />

<strong>the</strong> specifications of <strong>the</strong> printer. On UNIX platforms, <strong>Oracle</strong> <strong>Reports</strong> output must be<br />

formatted properly (e.g., PostScript or PCL) before sending it as a stream <strong>to</strong> <strong>the</strong><br />

printers. To print on UNIX, <strong>Oracle</strong> <strong>Reports</strong> mimics <strong>the</strong> behavior of <strong>the</strong> Microsoft<br />

Windows printer drivers internally. The next section describes more precisely how this<br />

mechanism works on UNIX.<br />

5.1.2 <strong>Oracle</strong> <strong>Reports</strong> Printing Mechanism on UNIX and Windows<br />

The diagrams below depicts <strong>the</strong> differences between <strong>Oracle</strong> <strong>Reports</strong> printing on UNIX<br />

and on Microsoft Windows.<br />

To support printing on UNIX, <strong>Oracle</strong> <strong>Reports</strong> internally creates logical printer drivers.<br />

A logical printer driver simulates <strong>the</strong> behavior of Microsoft Windows printer drivers<br />
