7.2.11.2 Nibble Mode
Transmission mode
EEE-1284 nibble mode
Synchronization
Refer to IEEE-1284 specification
Handshaking
Refer to IEEE-1284 specification
Signal level
TTL level (IEEE-1284 level 1 device)
Adaptable connector
57-30360 (Amphenol) or equivalent
Data transmission timing
Refer to IEEE-1284 specification
Extensibility request
When the printer receives the hexadecimal values 00H or 04H, the
printer responds in the following manner:
00H: The printer enters reverse channel mode, allowing data to be
sent to the host.
04H: The printer sends the device ID to the host
Device ID
[00H] denotes a hexadecimal value of zero. [SP] equals space code
20H
<00H><4EH>
