When the Thinkjet first came out, there was only one type of cartridge and you were encouraged to use the special Thinkjet paper -- plain paper would work but didn't absorb the ink as well, and so the printing would be sort of smeared but legible. Later, HP came up with plain-paper cartridges and sold both flavors. I don't know whether they still sell the cartridges for Thinkjet paper, but I guess that if you can get the paper you can probably get the cartridges too. They are the same cartridges as for the QuietJet printers (same idea but wider carriage) so I'd expect you can still get them in office-supply stores. -Frank McConnell
