By setting up caching, end users are able to download printer drivers, printer profiles and Printer Installer Client updates from locations other than the Printer Installer web server, allowing customers with many thousands of end users spread across hundreds of sites, connected with slow WAN links, to quickly download and install printers or client updates without overloading WAN connections.
There are two parts to the cache feature.
Specify the cache manger in the Tools > Settings > General page. The cache manager can be any computer on your network with the Printer Installer Client installed.
The cache location value (UNC path to a share) is set on an IP Address Range object's General tab and only applies to members of that IP address object.
Once a computer is designated as the cache manager (most often it is the computer hosting the Printer Installer web server) it will copy the cache files to it's local file system, then copy the cache to all of the cache locations specified in all of the IP Address Range objects. When end users make a request to the Printer Installer web server for a file that is in the cache, the web server will redirect the client to the cache location specified in the IP Address range object the client is a member of. The client will then obtain the file from the cache location.
To setup caching do the following:
The computer will now behave as a cache manager. To specify locations for the cache manager to copy files to, do the following:
Question:
Does the cache manager log errors to a log file?
Answer:
Yes. C:\Program Files (x86)\Printer Properties Pro\Printer Installer Client\PrinterInstallerCacheManager.log
Question:
Does the cache manager distribute the files to the cache locations at the same time or does it process each cache location one at a time?
Answer:
The cache locations that have the "Synchronize data files to the specified cache location" option enabled all get updated simultaneously by the cache manager.
Question:
Does the cache manager copy all cache files to the cache locations as soon as they are created in Printer Installer Administrator?
Answer:
Yes. As long as the IP Address Range's "Synchronize data files to the specified cache location" option is enabled.
Question:
Does the cache manager copy the cache files to a local folder before copying them to the cache locations?
Answer:
Yes, the files are copied to the cache manager's "C:\Program Files (x86)\Printer Properties Pro\Printer Installer Client\cache" folder before being distributed to the cache locations.
Question:
What files are copied to the cache locations?
Answer:
Question:
What if a printer file has not been copied to the cache location and a user tries to install the printer.
Answer:
If the needed file is not found in the cache location the user will be shown an error stating that the printer could not be installed.
