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.
