HIGH RESOLUTION GRAPHICS
Up until now all of the dot graphics printing we have done has
been with your printer's normal density mode. This can give
you some pretty sharp images at great speed. Sometimes
though, you may want to create an image with even higher
resolution. This printer has seven graphics modes you can use;
they're summarized in Table 7-2.
