inkblot: Inkblot reports on the remaining ink levels in a wide variety of USB
inkblot: and Parallel connected printers. Inkblot provides an ink status
inkblot: notification, and can provide a more detailed dialog showing the
inkblot: level of ink remaining to your printer. Inkblot uses libinklevel to
inkblot: detect your printer on first run. Where available, the status of
inkblot: individual colour ink reservoirs is shown. Inkblot lives in the
inkblot: notification area, and uses session management to ensure it remains
inkblot: available once added to your setup.
