Hold printing until buffer is released
EIA-232 Syntax:
ESC 7 or X'1B37'
Purpose:
If the system can not 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.
