Two issues were found that prevented the Image printer from communicating. The Image printer requires the binary communication commands with the 6370. Neither issue was in the driver itself but in the common communication code that passes binary data to and from the 6370 board.

1. Single character commands would not be sent to the printer. There was a bug with a single character string that resulted in the command not being sent. This was intrroduced in the restructuring done in SCN 4139.

2. For binary communication the code did not wait long enough for the response when using the new protocol introduced in SCN 4138.
