It could be that Epson were correct in the first place - although companies are selling cables that they claim will work with the 440
Are you absolutely sure that the printer is working? Have you tried it on another PC recently?
Some things that you might want to try - cannot give any guarantees that this will work though. Also I have very little experience with Vista!!
1.
Device Manager. Check for problems indicated by a yellow exclamation mark or red x. I think you will find it by going to Start / Control Panel / System Maintenance / System / Device Manager. Do you see any yellow exclamation marks next to any device
2
Printers. Check to see if any Printer installed and remove it
Goto the Start button then Control Panel, click Hardware and Sound, and then click Printers. If you see that you have a printer installed if so delete it then make sure that you have disconnected printer and cable, then restart your computer.
With the above checked you can then attempt to install your cable then your printer
1. The cable should be plugged in and properly installed before you attach the printer!
Without printer or cable attached switch on computer. When Windows fully loaded plug in the cable only and wait for Windows to load the default drivers.
2. Then plug the cable into your printer and turn it on - it should reinstall itself
3. Next Select the “Ports” tab. Find “USB001 Virtual printer port for USB” and place a checkmark in the box. As per the instructions in last post
