Overall operational Notes
Spool space - Qimage preserves full image detail when printing to your printer, regardless of print size. For this reason, your printer may require a very large hard drive "spool" file. Requirements of over 500 megabytes up to several GIGAbytes of spool space are not uncommon when printing a few dozen images in one image document. Please make sure that your print spooler or print driver is pointing to a drive with plenty of free space for spooling high resolution images. In addition, there should be plenty of free space on the drive where Qimage itself is installed (if this is a different drive from the one your print spooler uses).
Qimage performance - The amount of time that Qimage takes to spool a print job is directly related to the settings under "Edit", "Preferences", "Printing Options". The higher your settings, the longer Qimage will take to process them (and the better your prints will look in general). Note that Qimage normally generates much larger spool files and takes a bit longer to process your images than the average printing program due to the super high quality interpolation being performed. Choosing an interpolation setting of "None" under "Print", "Print Interpolation" will cause Qimage to print as fast or faster than other printing programs while generating prints of about the same quality as other software. We recommend, however, setting the interpolation to "Max" or "High" with the interpolation method set to "Hybrid".
Thumbnail storage - Qimage thumbnails are normally stored in a folder called "Thumbs" directly in the Qimage Application Data folder (Use "Utilities", "Explore Qimage Application Data" to see this folder). After periods of extended use (browsing many images), the thumbnails can occupy a large amount of space on your hard drive. You can click "Utilities", "Manage Thumbnail Cache" for options regarding management of thumbnails.
Raw cache - Similar to thumbnail storage, Qimage uses a folder named "RawCache" to cache raw photos for the "Lightning Raw" feature.
