Description

Name: jk109818			Date: 07/29/2002


FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :

Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
I am trying to write a program that will perform
silent printing to a card printer.  Everything seems
to work when printing to another printer that we have but
nothing seems to happen when the program prints
to the card printer.  I tried playing around and
noticed that an exception gets thrown when
trying to get default values from the printer.

EVALUATION Looks like we are accessing an array with 0 size. To avoid this exception, we need to check for mediasizenames.length > 0. ###@###.### 2002-07-29 No longer reproducible with the recent fix for 4701198 but length still needs to be checked. ###@###.### 2002-09-04 ================================= Fix: Added check for length = 0. ###@###.### 2002-09-16 ====================================
