[tcoop]

Can someone tell me the difference between the HP hpc6657a tri color ink
cartridge and the hpc6658a photo cartridge? Thanks for the help...Tom

Seems I saw somewhere that the photo cartridge uses pigment black.

The #57 cartridge is cyan, magenta and yellow. The #58 photo cartridge has
light cyan, light magenta and photo black (dye based). Together they can
provide photos with less visible grain. For most of the printers that use the
#58 cartridge it replaces the #56 pigment black cartridge. Some printers such
as the Photosmart 7960 or 7550 can hold all three at once.

There is also a #59 photo gray cartridge which has light gray, gray and photo
black. In some printers it can be used in place of the #58 for better B&W
printing. When used in the 7960 or 7550 printers in conjunction with the #57
and #58 cartridges it provides more detail.
