In one of the documenation files, extend.doc, it tells how to access them. In the MSDOS case, the ega is device 0 and the epson driver is device 1. One merely gives the interpreter the (extended postscript) code 1 getdevice setdevice and Ghostscript then sends all output to the second (epson) device. For the UNIX version I don't know what the default setup is, but my guess is that you have to check to see that the epson driver is mentioned in one of the make files, so that it gets included when the whole thing is compiled. Then just access it using the above sequence with the 1 replaced by the appropriate driver number. By the way, with my setup I can't get a whole page of output. It does start to print and after printing about 10% the printer just stops. My guess is that there's not enough memory for a full image at epson resolution, but since I don't know C I'm not sure. After looking at the source for a while, it seems there is some kind of virtual memory handler, but it doesn't seem to be working in the version I got. (I've tried it on machines that all have 640K base memory, and either lots of expanded or lots of extended memory, all with no differences.) Does anyone know if I should reset something in the configuration and recompile, or is there another extended postscript sequence that enables virtual memory? This is a really *great* program, and it is certainly extremely useful as it is. The epson (or laserjet) driver would really be icing on the cake, though.
