EO Mnemonic - End Output Transparency (Printer Channel and Printer Device)

Syntax

'EO'

Description

The 'EO' mnemonic turns off output transparency set by the 'BO'mnemonic. When transparency is on, all data is passed through the device driver without translation except for the 'EO' and 'RM' mnemonics. 'EO' prevents the interception of characters that are special characters to the driver, such as ESC. Standard (two character) mnemonics are sent as $1B$ (ESC), plus the characters representing the mnemonic. Long mnemonics are sent as $1B$, plus a length-byte and the characters representing the mnemonic.

Data printed in output transparency are sent to the printer immediately. The data in the line buffer will not be sent until a 'CR', 'LF', 'FF', or slew command is sent. To intermix transparent data with a typical print command, use serial mode on the printer. This, however, removes the 'cursor' positioning capability in parallel mode.
