Raster Graphics | Epson 8900 Series specs

The printer offers the following print-quality levels and speeds.

qLetter quality (LQ) — high-resolution, 32-dot by 18-dot characters at 100 characters per second (cps).

qText quality — medium-resolution, 15-dot by 9-dot characters at 240 cps.

qNormal draft quality — low-resolution, 9-dot by 9-dot characters at 400 cps.

qRapid Print draft quality — low-resolution, 7-dot by 9-dot characters. This mode is only valid for character spacings (pitches) of 12 characters per inch (cpi) and 15 cpi. These character pitches allow the printer to print at speeds of 480 cps and 600 cps, respectively.

Raster Graphics

The all-points-addressable raster graphics mode lets you use your printer to produce pictorial material, such as charts, graphs, special characters, or almost any design you can devise. Special commands allow you to design images of any shape by causing the printhead to print dots in the appropriate places. (See Chapters 4 through 8 for information about raster graphics commands.)

The best way to print graphics is to use one of the many commercially available application programs. These programs let you design images by drawing them on your computer monitor and then issuing a command to send them to your printer.
