Hi, I boot freedos (which is installed in a partition of the hard drive). I type debug, then I type d 40:8 The first line looks like this: -78 03 00 00 00 00 C0 9E I tried swapping 03 with C0, as well as with 9E. It rendered the drive c: unreadable. I tried changing 03 to 01, 02, 04, 05, 06, 07, 08, 09, and 10 ---all of which did not help with the clipper printing problem. I tried changing 78 to BC--still cannot print. I tried changing parallel port address in bios from 378 to 278 ---cannot print. When I went in to bios again, it apparently went back to 378 by itself. Is there anything else I can try? I would like to reiterate that, when I'm using the clipper program through command prompt of windows 7, it could print as long as I use the printer pooling --check boxes of LPT1 to 3 all checked.
