Epson 4100 manual Parity

64 Configuration

7 Bits: Limits the printer's ability to handle graphics and restricts it to accessing only the lower character and control data bytes (0-127) in the character sets.

Parity

Pressing YES prints out the present parity bit status:

•None (factory default)

•Even

•Odd

•Mark

•Space

The parity bit follows the data byte transmitted from the computer to the printer. The printer can use even or odd parity to check that all data bits from the computer were received correctly.

None: No parity check.

Even: Data bits are either binary 0 or binary 1. For even parity, all of the data bits must add up to an even decimal sum. If not, the parity bit is set to binary 1 to make it so.

Odd: All of the data bits must add up to an odd decimal sum. If not, the parity bit is set to binary 1 to make it so.

Mark: Parity bit is always binary 1.

Space: Parity bit is always binary 0.
