oh no. Um..I don't know how to cancel it but I will research it for sure. It looks as though some others are watching this auction so maybe others will out bid you if we can't cancel it. But I will let you know.
It depends. I had two different HP printers that these worked on but I had to downsize so I gave my printers away and was found these in my filing cabinet. Does this cartridge 940XL in your manual for your printer? or maybe online you could see if its compatible with your printer.
