I have printed labels for a couple of years at Christmas on this printer with no problems.
Howver this year, when I print a "proof" and align it with a label up to the light the proof aligns perfectly with all the addresses in each box with margins top and bottom. However, when I insert the actual label the addresses are printed up by about one or two lines and overlap the edges of each of the labels.
I am using an apple computer and printing through Contacts. I get the same issue with either an iMac or Macbook.
It would suggest to me that it is a printer issue .....but what?
