Request you to help us on the below.
We have around 3000 QLN 320 printers with us. Recently, wee have developed a new mobile app and calibrating all these printers by sending the below ZPL command through Link OS to these printers from mobile app . The below mentioned calibration command worked on few printers and on other printers the media settings were not being updated even after applying the below calibration command .
Could you please suggest if there is any option or command to force the below settings
Calibration command : "! U1 setvar \"device.languages\" \"zpl\" <CR><LF> ! U1 setvar \"zpl.print_width\" \"576\" <CR><LF> ! U1 setvar \"media.sense_mode\" \"bar\" <CR><LF>! U1 setvar \"media.type\" \"label\" <CR><LF>~JC^XA^JUS^XZ<CR><LF>";
