4.6.4 Tips for Visual Basic
When programming with Visual Basic, limitations prevent data from 81h through 9Fh and from
E0h through FEh from being sent as characters. Therefore, you may be not able to print a part of
Page 0 (for example )in Visual Basic.
However, you can use the following procedure to send this data.
Dim Send_ data(0) As Byte
Send_data(0) = &h81 ’1 byte of sending data
