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 50.
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 when the print buffer is held. If the printer is set to hold on error
then one of these commands must be used when the error condition is
cleared.
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. To re-enable the printer, the
printer must be reset.
Data buffer management and batch printing
Marker command
Syntax
ESC = marker or X'1B 3D' marker'
Where:
marker = 1 byte marker: 0x00 and 0x01 markers are reserved.
Purpose
To allow the driver to monitor how much of the data in the printer's buffer
has executed. The EC Level command returns status with the EC bit set. If
you want to know when a specific command has finished execution, a
buffered EC level request could be sent following the command. When
status is returned with the EC level bit set, then the previous command has
been completed.
Remarks:
The marker will be sent as status byte #4 in place of the EC level of the
code, and Status Byte 9, bit #1 will be set to indicate that the EC level has
been replaced by the marker for this status. The status with the marker
will be sent when all commands received before it has been processed. If
only a partial line is sent to the printer (characters without a line feed
command), the marker will be sent before the line gets printed.
Example:
LINE 1 FGHIJKLMNOPQRSTUVWXYZ1234567890x'0a'
LINE 2 FGHIJKLMNOPQRSTUVWXYZ1234567890x'0a'
LINE 3 FGHIJKLMNOPQRSTUVWXYZ1234567890x'0a'
