VARIABLE TEXT BUFFER
Function This command sets the size of the text buffer and
the text overflow buffer.
Explicit Form
Implicit Form
VARIABLE TXTBFR txt ovf
V TXTBFR txt ovf
Parameters
txt
Size of the text buffer, in bytes. The
allowable range is 4096 to 65535, with a
default of 4096.
ovf
Optional; specifies the size of the overflow
buffer, in bytes. The allowable range is 0 to
(txt - 1024).
NOTE: Turn the printer OFF and back ON again just
before you send this command to the printer. Some
printers may ignore the
TXTBFR command if printer
power is not cycled first.
Comments When using this command, send it to the printer
with VARIABLE WRITE in a non-printing label
format. Do not use this command in stored label
formats.
The text buffer holds incoming ASCII data before it
is processed. The overflow buffer is part of the text
buffer. It begins filling after the rest of the text
buffer is full, at which time the printer will signal
the host to stop sending data.
Data sent via the serial port cannot overflow the
text buffer, providing hardware or software flow
control is enabled. Data sent via the parallel port
will overflow the text buffer if the size of the ASCII
label format is larger than (txt-ovf). Overflowing the
text buffer in Code Courier or Barcode Blaster will
cause the printer to lock up. Blaster Advantage and
Solus will print an error label if the text buffer
overflows.
Increasing the text buffer size will decrease the size
