I have an HP Deskjet 2600 all-in-one series. I want to sign up to Instant Ink, for which I need the printer's unique email address, similar to ovgo7654cyg15@hpeprint.com. I talked to HP support for hours and there is no way around it: they need this code to associate the printer to my HP account.
I have used that code to print but now it has expired. The ink cartridges are completely dry and nothing comes out when I print. The code is not showing on the Embedded Web Server page, and Help Desk cannot recover that code even with the serial number and the printer connected to the internet. (They say it's for security reasons.) Their solution was to buy ink cartridges so I could sign up for ink cartridges, which defeats the purpose: if I buy ink cartridges, I'll have no need for Instant Ink.
Has anyone succeeded in extracting the printer's unique email address without printing?
