Since you control the firing of every pin, you can print nearly anything with SR-lo/15 that you can draw (and probably better, if you’re like most computer users!). This can be used for creating “computer art” or drawing maps. Or, as we’ll show you here, you can use dot graphics to print your logo at the top of each letter you print.

Since you can print eight rows (seven with a 7-bit interface) of dots with each pass of the print head, draw a heavy horizontal line every eight rows on your graph

paper. And it may be helpful to write the dot values (128, 64,
