I don't suppose the cache ever clears out automatically, or any way to set it not the keep those files?
Actually, it does clear automatically either upon next restart of the Host service, or next use of remote printing feature, whichever comes first.
You can see that for yourself. On the Host computer open the folder and leave it open on the desktop. Then try to print to Remote Utilities printer from an application, like a Notepad for example. You will see that with each remote printing attempt the old files will be replaced with new ones in that folder.
If I want to remove the printer from all computers on our network is the best way to push out a new msi package with the option to install the printer unchecked?
Yes. When configuring your Host, make sure that you select "Pre-configure Host settings, do not change security settings" option in Step 4 of the configurator. This will ensure that you retain connectivity with the Hosts after the update.
If you only need to update few Hosts, you can do so without updating/re-installing the Host. Use the
uninstall printer driver button in the Host options. You can do so either manually on each Host or remotely via the
Remote Settings command.
Let me know if you have other questions.
