Label Buffering
The user may select one of three levels of serial buffering. With Full Buffering (the default) selected, the scanner will place all scanned labels into a buffer for transmission. This allows the operator to con- tinue scanning even though the previous label may not have been transmitted yet. Scanning will continue normally until the buffer is full, then scanning will stop. Scanning will continue when enough space is available for the current label.
When No Buffering is selected then scanning will be stopped until the current label is completely transmitted.
When One Label Buffering is selected the scanner will allow the oper- ator to scan one more label in addition to the label already in the transmit buffer. In other words, one label may be scanned beyond the label being transmitted.
