>Hi All,

>Does anyone know of an easy way to print multiple reports, all with different layouts, information, etc to files then easily concatenate them together for one monster print job? We have an almost infinite number of combinations of data and reports. For convenience sake we naturally have broken these into their component parts, printing each as needed. This suits all needs except the printing speed issue. (I want my cake and to eat it too.. <g>)

>We are dealing with a speed issue that results from multiple color print outs, each being a separate print job. We have been informaed that if we could concatenate all these teports into one file that this would markedly speed up the printing time.
