    I think the standard method is to lock the back buffer, and copy each pixel to a bitmap file, and save that file. I dont use OGL, so i cant give you any code, but that will work.

    If you can get an hDC I believe you can pass it to the Printer object.
    All contents of the above post that aren't somebody elses are mine, not the property of some media corporation.
    (Just a heads-up)

    Yep. As long as you can get a DC, you can print from that.

    Showing the image and taking a screenshot is probably the best way of getting it to a DC. THEN you could print it

    If you're interested just reply here and we'll give you some code
    Code:
    Temp = Me.GetIQ()
'Error 9: Overflow
'DON'T PANIC! :eek:
