The controller default part print message has a rotation of 270 degrees. The Keyence Print driver only prints one character of the default part print message. The single character that does print, prints horizontally instead of vertically. Because the message gets rotated by 270 degrees, the rest of the message is hidden in the screen and does not print on the part..

It is too late to change the default message for the driver. This will break existing customers installs that may use the default message. It is also too late to completely adjust the driver’s interpretation of the rotation property so that the default message prints properly. Again, any general adjustment will impact existing customers of the printer.

A new setup has been added that is enabled when the Keyence Part Print drivers are selected. It is called Adjust Part Print Rotation. The parameter has two options, 0 and 90. It defaults to 0 degrees for legacy reasons. When set to 90, it will add 90 degrees to the rotation found within in any print message definition. This effectively converts 270 degrees back to zero. All the other rotation options are shifted by the same amount.
