v After the first three lines, the printer will transmit back status with the
normal printer status: Status Byte 4 = x'04'.
v After the 8th line, the printer will send back status with Status Byte 4 =
0x05.
Reset line count
Syntax:
ESC 6 or X'1B36'
Purpose:
Resetting the line count lets the system track the print line where an error
occurs.
Remarks:
The line count is incremented at every print command. The count is sent in
every status message to the system. The count can go to 256 (X'FF'), when
it rolls back to 0. (See “Print character commands” on page 64.)
Disable line count
Syntax:
ESC 8 n or X'1B;38'n
Where
v n = 1, disable line count
v n = 0, enable line count
Purpose:
To temporarily not increment the line count. This can be used when
printing predefined messages, if the number of lines embedded in the
message is unknown.
Hold printing until buffer is released
Syntax:
ESC 7 or X'1B37'
Purpose:
If the system cannot send data to the printer at a speed needed to keep the
printer in constant motion, it can hold the printer queue until it sends all
data lines for a transaction.
Remarks:
The printer must be printing one line while processing the next line. If the
printer is unable to completely process a line, the print speed reduces to
half.
The line count is reset when the buffer is held.
