Printer Maintainer - 1 Year Subscription - macOS, Windows - [Cancel Anytime]:
Printer Maintainer sends a color text page to printers to prevent inkjet printer heads from drying out and getting clogged. You don't want this to happen, because as a minimum, you will have to spend time cleaning the clogged print heads. And if left for a long enough timeframe, it may be necessary to throw away the cartridges before the ink has been fully used.
This app can work with as many printers as you may own, this feature can be helpful if you have a print shop full of printers.
On macOS, Printer Maintainer is designed to be scheduled to run at regular timed intervals by the Calendar app or 3rd party scheduling apps like the Scheduler for Macintosh or Task Till Dawn. On Windows, the Windows Scheduler can be used to schedule the application.

The File menu includes the Save LiveCode Stack... menu item. This menu item saves the entire source code of the application to disk.
Things you can learn from the source code include:
• Using custom properties to store binary data.
• Saving and restoring printer and page setup info before printing.
• Setting up an event based countdown timer within an app.
• [macOS] Compare sandboxing limitations working with printer icons. See the last screenshot in the photos to see that the actual icons for the printers are displayed in the list of printers. In a sandboxed environment, it isn't possible to run the sips command to create a PNG from the printer driver ICNS file. If you re-build the stack using LiveCode to run on your own computer, you can remove this limitation.
• [Windows] On Windows, the generic icon of the Printer Maintainer app is used to represent each printer, since these icons aren't straightforward to read from the drivers.
• Includes: .com Solutions Inc. developed Button Bar widget.
