Signum! (don't forget the exclamation point!) was an amazing piece of software. The key to its incredible print quality: carefully hand-crafted pixel fonts with incredible attention to detail.

With a 24-pin printer the output beat vector fonts on a 300dpi laser printer at the time. The actual resolution was higher than a single pass of printing with the 24 pins. Signum! would advance the print head in minute amounts and overprint to achieve its remarkable quality.

Printing a single page at maximum quality took a while... Think minutes per page instead of pages per minute. But it was very impressive.

Fond memories!
