Laserjet 4630 suddenly starts duplexing after years of NOT duplexing?

[EPPack]

A big part of the reason we bought this device some years back was because it offered duplexing. However, I could never get that to work at all, and was resigned to printing the second side manually. This morning, however, very very oddly, I printed a two page doc out of Word (same version I've always had) and after it printed the first page but before fully ejecting it, I saw a message I'd never seen before: Something to the effect the ink was drying. And then it pulled it BACK into the printer and printed on the back side!! 

I've made no explicit changes whatsoever to the print dialogs/settings, Word settings etc etc, but I'll be darned if I know how and why, after a bunch of years it suddenly started working the way I thought it should have from the beginning.

Thoughts?

The OfficeJet 4630 is an auto duplexing printer model:

To print in automatic duplex you need a compatible print driver that knows how to send the duplex print command to the printer.  If the automatic duplex printing feature started working all of the sudden then my guess is that your print driver updated without your knowledge.  As a result you now you have the full functionality of the printer that you may have been missing out on.

We would have to know specifically what that error message is to assist you.

Aha! The printer is actually attached to our second laptop, to which I have full shared access. That laptop is my Luddite husband's, so he never notices what gets changed, etc, as long as it works. And he rarely prints, so there you go. And while I rarely need to print in duplex, I've pretty much just done the manual replacement of pages. It may  well have updated that driver a LONG time ago.

Sorry, I didn't make note of it when it occurred, as I was so surprised to see it. I don't have the *exact* wording but I think it was close to this: "please wait, ink is drying". I'll run a test to see if it shows again, but that's very close. Not like there's a lot of space for a wordier message 🙂 But regardless of the wording, it is pretty obvious to me that it's duplexing.

 THanks!
