I am having a hard time printing from a Java Web Start application to a printer attached to a Windows server. I don't have problems with this printer and other (i.e Mac) applications. When I try to print from the JWS app the job gets sent to the Printer window but the Status is "On Hold (Authentication Required)". If I click the Resume button I get prompted for my (Windows) username and password, after that the print job goes through normally. I noticed the Print window shows this job's username as "System Administrator". When when I print from a Mac application the username is blank and the print job goes straight to the printer. The Activity Monitor shows I am the owner of the JWS process. On Tiger web start just prints normally. This is very frustrating. Any ideas?
