If they're persistently stealing traffic from my network then the printers administrative password is the least worrisome part.

Self obsessed to the point of absurdity? There was a vulnerability a few years ago where you could embed an HP Printer Firmware update into the middle of a print file by taking advantage of some insane JCL commands. You can also embed JCL commands directly into a word document.

So these researchers created a word document that when printed updates your printers firmware with a hacked version allowing an advanced persistent threat to live inside your printer.

If your printer has no anti virus or no intrusion detection then putting an SSL certificate on there is entirely pointless.
