Compaq IJ1200 2400 1200 B gutenprint-ijs-simplified.5.2 This printer is reported to work with the drivers for the Lexmark Z42, so it is probably a rebadged Lexmark Z42.<p> The Compaq cartridges have a little plastic tab to make them incompatible with Lexmark cartridges. Otherwise they are the same. I think you can break off the tab and use the other brand?<p> Consumables/Refills: color and black or photo cart.<p>
