Does ESL Print Driver work with a Web Proxy?

Question asked by a customer: Does ESL Print Driver work with a Web Proxy? We use a web proxy to filter out bad web sites when connecting to external sites (not to be confused with their proxy product). Is there a way to configure the driver with a Web Proxy address and port? Again, I know they have a proxy product, which makes the names confusing..... but this is a security appliance that many large corporations use to help secure workstations from Internet malware and malicious web sites. The issue I think is that the driver can't connect to the Web Proxy because it needs to be configured to connect to it. I have not seen any documentation on this; If not, then we can route around the proxy with a special configuration for your users.
