I am using the zpl string below to send data to and print a stored label on our ZT410 printer. Everything is working except the "^LS" command. It is very strange because the printer settings for left position reflect the data I provide( example -23). The problem is the label is not adjusted. The "^LT" command works. I can change it  and the label moves accordingly. Any help would be appreciated. Thanks

            string ZPL_STRING = string.Format(@"^XA                      
                                ^XFE:csa.ZPL                                                       
                                ^FN12^FD{0}^FS
                                ^FN11^FD{1}^FS
                                ^FN13^FD{2}^FS
                                ^FN14^FD{3}^FS
                                ^LS-23^FS 
                                ^LT12^FS                           
                                ^PQ{4}                          
                                ^XZ
                                ",
                                 data1,
                                 data2,
                                 data3,
                                 data4,
                                 data5
                                 );
