/******************************************************************************
* The real dumping routine. Few things are taken into account: *
* 1. The Nice flag. If TRUE each pixel is printed twice in double density. *
* 2. The Invert flag. If TRUE each pixel before drawn is inverted. *
* 3. The rendering mode and dither matrix flag if dithering is selected. *
* The image is drawn from ScreenBuffer ScreenTop/Left in the bottom/right *
* directions. *
* Unfortunatelly, there is a BUG in DOS that does not handle ctrl-Z *
* correctly if we open lptx: device in binary mode (should treat it as any *
* other char). Therefore I had to write to it directly using biosprint. I *
* dont like it either, and if you have better way to do it, let me know. *
