Workaround:
1. From AppleWorks, identify the ImageWriter II as a custom printer.
2. Under printer codes, select either subscript or superscript begin.
3. Insert an ESCAPE H 2016.
The H must be a capital H. The code ESCAPE H 2016 sets the form length to 14 inches (in increments of 1/144 of an inch).
4. At the top of the document, by typing the open-Apple O command and the appropriate code:
a. Insert the subscript or superscript begin, whichever you used in step 2
b. Set the page length to 14 inches.
You should be able to print legal size documents from this AppleWorks setup using the sheet feeder on the ImageWriter II.
The problem has been passed on to the product engineer.
