Do the taxes show on the screen when you select Print Preview?

If you select Setup | Reports & Forms | Invoice, is '[x] Print subtotal' still selected?

Did this just start happening when you updated to version 2016.2?

Does this happen on every invoice, or just one? Is the GST amount positive? If negative, it could be trying to print red and coming out invisible.

Are there multiple tax codes?  I did not test with that.
 
Does it happen with the Sample file?

Does this happen with the other invoice templates?

If you close everything and restart, does it still happen?

I'm testing with 2016.2, and it works on this workstation.

Hi, Thanks for the answer and sorry for the delay !

Do the taxes show on the screen when you select Print Preview?  No, they don't show

If you select Setup | Reports & Forms | Invoice, is '[x] Print subtotal' still selected? Yes

Did this just start happening when you updated to version 2016.2?  It was the first time, I tried it.  I used it for my suppliers, but that was the first with a client.

Does this happen on every invoice, or just one? Is the GST amount positive? If negative, it could be trying to print red and coming out invisible.  I try it with 3 different clients and it does the same.  Yes the GST amount is positive.

Are there multiple tax codes?  I did not test with that.  I have also one for + taxes.

Does it happen with the Sample file? They appear on the invoice made by Sage 50. 

Does this happen with the other invoice templates?  I only have one template ?

If you close everything and restart, does it still happen?  Yes

So, I suppose, it's something with my template I made.  It's the same template we use since 2013, maybe it's the problem.

Thanks a lot for you answer !
