Hey all, My company is having a weird issue right now. We have both XP and 7 machines currently deployed and just this morning across several sites we've had an issue where Epson receipt printers won't work on Win7 machines. These sites are unrelated and the base hardware differs wildly so I can't see it being a driver issue. I can also see Windows updates haven't been installed in a week or so so I'm unsure if I can point the finger at them. However, on to the issue, it appears that all the Epson virtual printer ports (ESDPRT001, ESDPRT002 etc) have been removed from these machines. When trying to uninstall the Epson Advanced Printer Driver 5 it will go part way through the process then show "Uninstallation failed. Close all applications and uninstall again from the beginning." The same message is shown when you try to install from the base package (just swap uninstall for install). I am unable to use the config utility to reinstall the printers using the USB auto setup function as it just fails (presumably due to the port issue). Disabling all Epson services and print spooler do nothing to resolve the uninstallation issue (all services are also starting fine). Devices and Printers still show the printer under "Unspecified" and it's listed in devmgmt as its' proper name, albeit without a driver installed. The only thing I found strange that may be related is that I couldn't install SQL Service Management Studio 2008 as whenever it would try installing it couldn't find the installation files that were unpacked mere minutes ago. All programs were run as admin and under an admin account too.
