public void PrintJob(PrintJob job)
{

}
//protected override void PrintJob(PrintJob job)
//{
// if (!Initialized) Initialize();
// StartDocument();
// Stream renderedDocument = RenderDocument(job);
// WriteDocumentToDevice(renderedDocument);
// EndDocument();
//}
protected override Stream RenderDocument(PrintJob job)
{
//device specific code
throw new NotImplementedException();
}
protected override Stream RenderDocument(PrintJob job)
{
throw new NotImplementedException();
}
protected abstract Stream RenderDocument(PrintJob job);
