There are sample applications on the websites for the latter two programs that are supposed to test the system, but I cannot get any of them to work correctly. I have downloaded and installed these two programs as well as RXTX, following the instructions as closely as I could. I also have found several web-sites which claim to allow access to the serial and parallel ports from Windows NT, XP, etc, including Parport and Userport. I also understand that Sun pulled the COMM API from their website, claiming that RXTX replaces it. I am aware that Microsoft does not allow Windows XP to have access to the ports directly, but supposedly I have that problem covered. If after troubleshooting you are still unable to print, contact your computer manufacturer or computer support for additional support.I need some assistance with accessing the parallel port using Java within a Windows XP Pro operating system. This will determine if there is a problem with this computer. If you have another computer, try installing your machine on that computer and printing. Remove any switchboxes or other devices that connect between them. Make sure the parallel cable connects directly to the computer and your machine.

If Yes, then the printer and driver are working correctly and the issue is resolved. Attempt to print a document or a test page. Other cable configurations may work, but connection loss is common.ħ. We recommend you use a shielded IEEE 1284 compliant parallel cable that is no longer than 6 feet. Do no use a Parallel-to-USB, Parallel-to-Serial, or a similar type of cable. Use a parallel cable with parallel connectors on both ends. The parallel cable should be directly connected to the machine and computer.
