Canon cp-330 prints only one haf of the picture

Question edited to fix errors in printer name format. Plus it is either a CP-200 or a CP-1200. There isn't a CP-2000.

This is the likely reason.

Also remove the cartridges, remove the printhead, and look for scraps of paper or lint in the area.

It is a known issue on these.

Can't help you with OSX; your printer should work, no idea why it doesn't but then, I don't know much about OSX.

Only half of the picture prints on my selphy cp 730 canon printer

if Vista and 7 is unsupported by the printer manufacturer, you are pretty much out of luck. If Vista and 7 say the printer is unsupported or un certified, run the manufacturer software if you want.

You doult run in emulate mode ... but for as cheap as printers are these days, why would you want to run in that mode?

you can download it from here http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=259&modelid=10074#DownloadDetailAct

make sure your printer printed an initialisation or alignment sheet once you installed the new cartridge.
you can try a partial reset of the printer and check if the printer prints fine,also there is an option of cartridge calibration in the printer properties or the printer software installed in your computer

Canon 330, but I'm biased as I have trained on the 330.

cleaner? as in the electronic version..those printers can get crusty when not used..might be some deposits inside the cartridge carrier area

Here is a direct link to the same problem with cp-220:
