Possible causes for your problem, Charlie...and Dan...
I also use an HP inkjet printer and have never used anything but a PC. A few thoughts: Your printer may think it's still connected to a Mac. When you switched to a PC, did you install the PC printer software, or just let Windoze find the driver? If you didn't install the software, that could cause formatting problems.When you tell the Avery "wizard" to copy the first card into the remaining 9 on the sheet, are you making sure they're all landing in same position on each card? Avery has several different card stocks...are you sure that the 'wizard' you're selecting to design your cards is the same one that's in the printer? Or it may be that you've installed the Avery software for a different version of Word than the one that's in your computer, or using downloaded fonts that aren't downloaded into your version of Word.Or...if your fonts or artwork are sized a little too large, it may be pushing each card a little further down...not enough to push the copy off the card till you're halfway down the page. That's the most likely cause. If you do a test print on plain paper, then hold it against the card stock and hold 'em up a light, you can check the alignment for all the cards and then make any necessary adjustments without wasting card stock. If you're using color or photos for your cards, you can tell the printer to print the test sheets in grayscale and in "draft mode"...that saves your color ink and also uses a LOT less black ink.Dan, since you're printing on photo paper instead of card stock anyway, save your card template on CD then take it to a photo lab to have it printed as if it were 8x10 "englargement" instead of using your own printer. Photo labs use the same chemical printing process for digital that they use for negatives, which has some major advantages: 1. Colors are a lot sharper and truer...and they stay that way a lot longer than inkjet or laser prints. I THINK it also costs a LOT less than printing color photos yourself. You can then print the line art map to your house on the back on your own printer before cutting the sheets into cards.
