Epson 400 Printer User Manual


 
dpi
Dots per inch. The dpi measures the resolution. See also resolution.
driver
A software program that sends instructions to a computer peripheral to tell it what
to do. For example, your printer driver accepts print data from your word processor
application and sends instructions to the printer on how to print this data.
economy printing
Printing in which images are printed with fewer dots to save ink.
error diffusion
This halftoning setting smoothes out edges by randomly placing dots of varying
colors. This has the opposite effect of the Finest detail setting.
ESC/P Raster
A command language that gives you control of your printer from your computer.
Commands in this language produce laser-like features, such as enhanced graphics
printing. (ESC/P is an abbreviation for Epson Standard Code for Printers.)
Finest detail
This printer driver setting feature automatically makes your printed images sharper
and clearer. This has the opposite effect of the Error Diffusion setting. Be aware that
this may increase the time required for printing.
font
A style of type designated by a family name.
grayscale
A scale of shades of gray from black to white. Grayscale is used to represent colors
when printing with black ink only.
halftones
Patterns of black or colored dots used to reproduce an image.
halftoning
Method of using dot patterns to represent an image. Halftoning makes it possible to
produce varying shades of gray using only black dots, or a nearly infinite array of
colors using only a few colors of dots. See also halftones.
high speed printing
Printing in which images are printed in both directions. This provides faster
printing.
initialization
Returns the printer to its defaults (fixed set of conditions). This happens every time
you turn on the printer or reset the printer.
ink jet
A method of printing in which each letter or symbol is formed by precisely
spraying ink onto paper.
