m n Description
A 41 Enable unsolicited status.
Note: A status message is returned immediately after
execution of this command. To enable these status
messages, the Status Sent to System setup command
must be enabled. See “Status sent to system” on page
141.
B 42 Disable unsolicited status
C 43 Disable transparent XON/XOFF
Purpose:
To process a command immediately.
Remarks:
Either the Release print buffer or the Cancel print buffer command must be
used in these situations:
v When recovering from a cash receipt print error
v After clearing an unrecoverable home error
After the printer resets, it defaults to not sending status unless requested. If
an error occurs, the printer appears hung, unless a status is requested. If
unsolicited status is enabled, the printer sends the error to the system as
soon as it occurs.
Note: If transparent XON/OFF is disabled, X'10', X'11', and X'13' can be
imbedded in returned status and data. (See “XON/XOFF control” on
page 29.) To re-enable the printer, the printer must be reset.
Data buffer management and batch printing
Reset line count
EIA-232 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 156.)
Disable line count
EIA-232 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.
