Venue 11 Pro 7130, printer offline

I have a Dell Venue 11 Pro 7130, connected to an HP Deskjet 1050. Suddenly, the printer is listed as 'offline' and I can't change it, even if disconnecting and reconnecting the printer, turning printer on/off, and so on. The Dell does not recognize the printer as connected, so I can not even reinstall the printer driver. It is definitely the Dell Venue that is the issue, as I can print if I connect the printer to another computer via the same USB cable. The only change in the Dell Venue that I can think of is a recent BIOS upgrade.
