= SUMMARY =

ETX/ACK handshaking can cause characters to be dropped during the printing process. Word will sometimes put the ETX in the middle of the 16-byte string of characters sent to the printer resulting in the characters after the ETX being lost.

This applies only to printers using ETX/ACK. Since no dot matrix printers supported by Word use this protocol, the problem occurs only with daisy wheel printers.

The solution is for you to disable ETX/ACK on your printer by changing the appropriate printer DIP switch and modifying the SerialInterface: flag to a value of 40960.
