website? If you scroll down under ''Printing'', you'll see where it say's,
'Labels are printing out of line' . This affords you 4 possibilities. My guess is, if you've spoken to Tech Support, these areas may have been covered. On the outside chance, they haven't been, it's worth reading.
If the above doesn't help, maybe some ''poking around'' the site itself will. There's a great deal of information there.
I have downloaded numerous templates (mostly from Avery) for making cards, labels, etc. I use the Avery labels or cards or whatever, and I enter my info on the template, but it doesn't print correctly on the actual label. In the case of labels, the first one is just slightly off, (usually too high or too low), but the labels get increasing off target as they print on down the page. Greeting cards and other things like specially sized photo paper have the same problem. For example, a 5x7 card doesn't print onto a 5x7 photo paper correctly.
Any suggestions would be welcome, as I have spent a lot of time on the phone with tech support and they don't seem to know what the problem is.
