How to replace Ink Cartridge for HP DeskJet 4100e, 4155 All-in-One series | HP 67XL Tri-color Black 

Compatible with HP ENVY 6055, 6052, 6058 models: • HP Envy Pro: 6455, 6475, 6452, 6458, 6454 • HP DeskJet: 1255, 2755, 2752, 2732, and DeskJet Plus 4155, 4152, 4140 printers

I have the Deskjet 4100e series. Hp sent me HP 67/305. This does not fit my printer yet HP says it does. I have been using HP 67XL which I don’t have a problem with ?? Why change something that works with one that doesn’t?????
