Stardraw's default print setting is "Fit to Page" - this means that it will size the printout so that all the objects in the drawing will fit onto a single page.It is therefore very likely that there is an object or collection of objects in the opposite corner of the drawing to the objects that make up what you assume is the full drawing. It is common to find symbols (or 'blocks' in AutoCAD terminology) offset by a significant distance from the main contents of the 'modelspace'.
The quick and dirty fix would be to open the drawing, drag a selection rectangle around the corner opposite to the main drawing and delete whatever is selected (you should see selection handles when the offending objects have been selected). The objects may not be visible, even at very close zoom, because of color or their nature - it might be a single 'point'.
Alternatively you could copy the objects you do want, i.e. the main drawing, and paste them into a new drawing.
I hope this is helpful.
