Hello, I was developped with Java 1.1.4, 1.1.5 and 1.1.6,
but I found a problem when I tried to print a document with
severals pages. I found the BUG in Java Developer Connection=20
(bug id 4084038) that was fixed in releases 1.1.7 and 1.2beta4.
I downloaded the Java 1.2beta4 because the 1.1.7 is not available,
and when I test my application I found another BUG: using=20
Graphics.drawString(String,int,int) the JVM draws a line from each
character printed to the upper-left corner of the page.
Here is a simple code that show the problem when run in Windows NT 4.0:
There are 2 (two) files, MyPrintTest.java and MyPrintTestWindow.java
