cannot print from envelope tray on HP 4300

So when you open an envelope, and go to File, Page Setup, is the envelope feeder selected for both first and second pages?  If not, select it and try it again.

I'm not sure the File, Page setup applies. I'm using the "Create Envelopes" command, then "Print". There doesn't appear to be a Page Setup option at this point.

To me, the area with the red circle around it indicates Word should try to pull from the Envelope Feeder.

It works from Notepad, but Word doesn't seem to be able to do it.

Any other ideas? Maybe you've got a better way of printing envelopes. The whole thing is going to be automated with VBA, so anything that works is fine.

If you click the Options button, it should say Envelope Feeder... but you're telling me that these are all set to print to the envelope feeder, yet it still isn't pulling?  

If you're writing it in VB, you shouldn't really worry about this at this point because you can set it in the VB....with code:

        ActiveDocument.PageSetup.FirstPageTray = wdPrinterEnvelopeFeed
        ActiveDocument.PrintOut

Hope this helps :)

I keep getting the error. I've tried several things. But what I'd like to get to is the following:

    lngSource = InputBox("Enter the WdPaperTray code number", strTitle, 0)
    appWord.ActiveDocument.Envelope.PrintOut FeedSource:=lngSource

0 prints ok, 5 (WdPaperTray.wdPrinterEnvelopeFeed) and most other values display the error shown below in the attached screen shot.

Again, if I print from Notepad I can get the EnvelopeFeed tray to work. But I can't get it to work from Word.

Any other ideas?

I just loaded Office 2007.  Let me give it a shot....

And you're trying to set the envelope feeder from VB right?

I've been unable to get to the physical location until last week (working from out of town remotely). Sorry for the delay.

This is what I finally got to work:

appWord.ActiveDocument.Envelope.PrintOut FeedSource:=0

For some reason "WdPaperTray.wdPrinterEnvelopeFeed" wouldn't work.

Glad you finally got it to work.... sometimes you just have to record a macro to view what the tray names are .....
