I would try to suggest that you remain friendly with those responding to try and help, or help may not continue to respond. I think what USAFRet and I are trying to say is that, from experience, trying to use printing the way you are describing is going to cause great frustration with your customers, which will likewise cause great frustration for you. Think about it this way. Every customer that comes in your door will potentially want to print something. They're not going to know how, so it will be up to you to do it for them.
Creating a shortcut is actually going to be creating a mapped network drive. You first have to put in place many things to have this working properly, so it's not necessarily just one easy step and that's why we haven't given you specific details yet. First, you will need to ensure that you have the proper user account settings on your end client computer and the main, server computer. Is this currently set up in a domain environment, or workgroup environment? Simply put, the server PC will need to share out a folder and allow access to the user (or users) that will be logged in to the client computers. We don't know your current system, or how your user accounts are set up, so this is difficult for us to try and walk you through without knowing much more detail.
Once the shared folder is set up with permissions for the end users, then on each computer system you will need to set up a mapped network drive to the server and the share, such as //COMPUTERNAME/SHAREDFOLDER. Again, this is going to depend on DNS settings and domain settings. If you are in a domain environment you can set up an automatic mapped network drive within the User Properties of each user within the Domain Users and Computers. Otherwise you will need to go to each computer, log in as the end user account, and manually create the mapped network drive. This will show up as a new hard drive on the computer, such as G:/SHAREDFOLDER.
