HP Photosmart C7280 Prints Crooked

Does the c7280 use seperate Magenta and PhotoMagenta cartridges? If so make certain the right cartridge is in the correct slot.

Clicked on Start/Control Panel/PrinterI. Clicked Add a printer. Obtained (Copy 1) of my HP Photosmart C7280 all-in-one printer. Right clicked on (Copy 1)/properties. Opened Ports tab. Saw comment "Print to the following Ports. Documents will print to the first free checked port." A listed USB Virtual printer port, showed three printers -- my first printer, my copy 1 (& my fax printer) -- was unchecked. I placed a checkmark in this Port box. Both the original printer, and my copy 1 printer are printing just fine. *I have not checked to verify that my fax is functional.
I did rename the original "color". I renamed Copy 1 as "grayscale", and --under printer preferences, checked, under "color options", to print in greyscale.

There you go. Good luck!

Here is the solution. It's real simple.

Here's a simple solution. It's easy! Instead of it being the C7280 - it's the C7250 - should be the same driver however. Good Luck!

ahem...well..this has a lot to do with the rgb to cmyk issues on the transforms. You may need to see if the Photosmart is compatible with the Adobe Photoshop C2 transforms..
