Hi Netters(tm), I've got this problem of having to draw simple vectors on an HP IIP laser printer. The scenario is this: The page consists of a lot of text with one area containing a simple graph (just a few connected lines). If I position the `cursor' at the last printing position, can I simply enter graphics mode and start `plotting'? I've figure that lines may be drawn with relative (or absolute if that's required) cursor motions (+/-x dots, etc) and points plotted by drawing 1x1 dot rectangles (yes, utterly yech). The only problem is this: it does not work! Note: I do *not* want to generate a full bitmap and download that! Question(s): Do I have to be in graphic mode to draw the rectangles? I've only got a User's Manual, no Programmer's Manual, so it only lists the command codes. Will the `define rectangle height, define rectangle with, fill rectangle (Esc*c#a#b2P) sequence do the `plot'? Will the move cursor with relative coordinates (ie. # prefixed with +/-) work for move the plot position? Alternatively: Has somebody perhaps got sample code to show how the vectors can be done? Any pointers will be highly appreciated.
