Printed photos from Aperture 3.2.1 have lines through them - don't get that when printing from iPhoto

Question

I recently downloaded Aperture 3.2.1 and after editing a couple photos (love that process!), tried to print them.  Both had horizontal lines across the entire photo.  I don't have this problem when printing from iPhoto.
As an FYI, I have this problem when printing from PSE too, but worked around it by importing edited photo back into iPhoto and printing from there.  I don't want to do that with Aperture, because they have much better printing choices.
I have a Canon MP 500 & a Canon IP 4300 - same issue with either one.
I contacted Canon tech support and got this reply:
We appreciate your correspondence regarding your PIXMA MP500. I am sorry that lines are printing through photos printed from aperture.
If aperture is the only program the issue occurs with then the print setting in aperture will need to be changed. You will need to use the icc profiles for the paper you are using. For details changing the print preferences in aperture please goto: http://www.redrivercatalog.com/profiles/how-to-use-icc-color-printer-profiles-ap erture-3-canon.html
I looked at the link and basically had a brain freeze.  It was very complex, and I was concerned that it was for Red River papers - I use HP paper.
I called HP to get their instructions for icc color printer profiles - complete zero.  They said it's a printer issue and would be happy to sell me a HP printer.
Please, can anyone help a struggling Aperture newbie?  I'm so frustrated.
Thanks - Jma

Hello Kirby,
Your recap is correct.  I ran Apple Software Update and both programs are up to date.  I looked on Canon's site and there are no new firmware updates for either printer.
When I select "print" in Aperture, I've selected the Canon MP500.   Under the "Rendering" section, the color profile offers six different selections that include the MP500.  I've tried them all.  They all have lines through them.  There is a note, in grey, beneath the Color Profile box, that says to "Turn off color management in the printer driver".  I have absolutely no idea how to do that, and I've googled it, to no avail
Under "Render Intent" I've tried both selections - Relative Colorimetric and Perceptual.  Still, lines through both.
This is really discouraging.  Both printers work perfectly fine - with iPhoto, so it's hard for me to justify buying a new printer.  And how do I know I wouldn't have the same problem with a new printer?
Fingers crossed that this can be resolved.  I have several photos I'm supposed to be printing for gifts.  And if the problem is in Aperture or PSE, won't the lines still be there even if I use one of the online printing companies?
