A long time ago, I remember reading a tip on how to make the Imagewriter print bi-directionally. (It was something like pressing command option shift when clicking on OK in the "page setup..." dialog box.) Does anyone know for sure? And does anyone know why this isn't the default? -Bri -- --- ---- Brian Kenney kenney@hsi.com ----- 3M Health Information Systems Wallingford, CT ------

Question 1 -- Nope! Question 2 -- Apparently the Imagewriter on the return pass may not align the dots with those when the print head is going in the other direction. The printout doesn't look so good Hope this helps -- Jeff Wiseman: ....uunet!tellab5!wiseman OR wiseman@TELLABS.COM

Keep trying. You can't press them all, because one of the modifiers turns the feature OFF. You do have to select the "faster" option, but I don't remember which of the modifiers to use, either. Don't you just LOVE hidden things like this? It provides so much good detective fun... -- Steve Dorner, U of Illinois Computing Services Office Internet: s-dorner@uiuc.edu UUCP: uunet!uiucuxc!uiuc.edu!s-dorner

And once you get bidirectional printing ON, if you can't find the modifier to turn it OFF, just replace the "Imagewriter" file in your System folder with a fresh copy. I had to do that. bill

One of the reasons the IW does not print bi-directionally is because of the heat factor. The mechanism basically gets a 'rest' when it's traveling back. Over the course of a large document it seems like it's a bad idea to have the print head heat up. Don't you agree? What I'm not sure about is what exactly that page limit is. For example, is it ok to print bi-directionally on a five page paper or ten ... ?

It does print bidirectionally in "Best" mode. The ImageWriter I print head could be damaged by overheating (I did it). The ImageWriter II is supposed to protect itself from such (by ceasing to print if the head gets too hot). -- Steve Dorner, U of Illinois Computing Services Office Internet: s-dorner@uiuc.edu UUCP: uunet!uiucuxc!uiuc.edu!s-dorner

Actually the suppression of bidirectional printing is not related to heat. The printer firmware prevents excessive heat buildup by simply pausing the mechanism between scans when this is necessary, so you need not worry about heat. The reason bidirectional printing is suppressed is that it looks bad on *some* ImageWriter II's. David Casseres Exclaimer: Hey!

The problem seems to be that the print head move,emt has some slack in it, so
that moving to the left places the dots in other places than moving to the
right.
Aren't the two smaller, difficult-to-change, "factory set--do not touch"
DIP switches supposed to be able to correct that problem?
I dimly recall a posting a few months ago...
