I have a similar problem, printing to an hp deskjet 1220c, its only been on one drawing thou, but no mater what i did the drawing top was cut off, even when resizing the entire image, the print preview show the image as being inside the boundary box/printable area but the plot came out with the top missing, the only way to get a hard copy was to save as a jpeg and plot out through another package, so far its only happen to one image? but i suspect it was something to do with the amount of imported objects at different scales. apart from that minor problem, impressions is turning out to be a very useful tool.
