Printer Offline 
When the printer is switched off or unplugged the printer can display the error offline, 
it will also be greyed out, to fix this make sure the printer is switched on and plugged 
in with a working USB. 
 
 
 
 
 
 
 
Default Printer 
The Brother printer needs to be set as the default printer in windows, this will then 
print from the Petrol and Diesel programs, to check this go to start>control 
panel>Devices and Printers and then check that the printer you have has the green 
tick like below. 
 
 
 
 
If the printer is not set as the default printer (no green or black tick) right click the 
printer and select “Set as default Printer”
