The #45 and #56 are pigmented black cartridges. The #45 delivers 42mL of black
ink, has 600 nozzles and is used in literally scores of printers. It was
introduced in ~ 1995 and has been a workhorse for black text for many of HP's
DeskJet, Photosmart and all-in-one units, as well as some large format
printers. The #45 list price is $29.99 USD.

The #56 cartridge was introduced in 2001. It delivers 19 mL of pigmented black
ink, has 416 nozzles and is used in the DeskJet 5xxx, Photosmart 7xxx, PSC
21xx, 22xx, 24xx and 25xx printers. The #56 has a list price of $19.99 USD.
Most printers that accept the #56 black cartridge are designed to swap this
cartridge with a #58 photo cartridge which provides six ink printing in these
printers. The #56 cartridge has drop sizes about 1/2 those of the #45
cartridge.

The #78 cartridge has 432 color nozzles and delivers a total of 19 mL of color
(cyan, magenta and yellow) ink for the 78D version with a list price of $34.99.
There is also a 78A cartridge that delivers 39mL with a list price of $54.99.

The #57 was introduced with the Photosmart 100 in 2000, and is also used in all
the printers that support the #56 cartridge. The #57 cartridge delivers 17 mL
of color ink and lists for $35.99 USD. The drop size for the #78 and #56
cartridges are similar at 5pL.

There are also the #58 photo and #59 grayscale photo cartridges that deliver
17mL each and a list price of $24.99. The 59 cartridge is used in the
Photosmart 245, 7260, 7760 and 7960 printers. When used with HP premium Plus
Photo paper the #57/58 cartridges give 72 years of lightfastness under glass,
or 49 years in open air.

If the print you saw was a photo it is possible that the printer had not been
set to use photo paper. While the 5652 and 6122 both have an automatic paper
type sensor that adjusts the print modes for photo printing, all the printers
that ship with the 27 and 28 cartridges require the user to select the proper
paper type for best results.

The 5652 and 6122 will be similar for black text quality. For photo's the 5652
has an advantage because it can print full bleed (totally edge to edge on all 4
sides) on standard photo paper sizes and can also accommodate the optional #58
photo cartridge. With the photo cartridge installed the print quality will be
better and have better lightfastness. With the 56/57 combination installed the
5652 and 6122 will have similar print quality.

If you will be doing a lot of printing and are not so concerned about photo
quality the 6122 may be a better choice since it can accommodate larger
capacity cartridges. For photo printing the 5652 would be better.

Yes, but the 56/57 combination is more cost effective. The 27 and 28 are lower
cost but they also hold less ink.

Very true. I've had my 5550 since Sept., 2002 and immediately ordered
refills for B/W & Colour carts, for a total cost of $40 (can); I've
refilled the B/W 5 times and the colour 3 times and am still working
on the original refill kit.
