I have the good(?) fortune to be going to Chicago on business next week, and having had a quick look have seen that cartridges for my HP Photosmart 7150 are around 30% cheaper - so I was planning on picking up a few, particularly as the Photo cartridge I ordered on the 1st April is still on back order!
However, whilst the product sheets for the the US and UK versions of the printers have the same part number for the printer (q1604a), the cartridges differ. For example the UK black cartridge is C6656AE, whilst the US is C6656AN.
Whilst I'm reasonably confident that they will work, does anyone know for certain? And, are there any differences e.g. chemicals?
click here it appears HP code the product differently for varous geographical reasons, my guess is it's a packaging thing with each variant having different language combinations on the box. There is no indication that the cartridges are different in any way.
