Yes. Each PrintGuardian M5 connects to and monitors one printer 24/7. If you have multiple printers, you can add multiple M5s to the app and switch between them.

We do not love subscriptions either, but there are ongoing costs to run the cloud service, mobile apps, notifications, billing, updates, and support.

We kept it intentionally low at $19/year after the included first year, so PrintGuardian can keep working long after the hardware sale.

The iOS and Android apps show printer status, current mode, temperature, humidity, recent print usage, recent cleanings, consumable levels, and power failure detection when your Wi-Fi stays online on backup power.

You can wake or put the printer in standby, run one or more cleans, monitor ink and waste levels, and receive alerts for low ink, full waste tank, film errors, and high or low temperature or humidity.

PrintGuardian monitors printer activity, temperature, and humidity, then uses its maintenance algorithm to wake the printer, run a cleaning cycle, and put the printer back to sleep when needed.

Cleaning uses ink and moisturizer, so the goal is balance: keeping ink fresh in the heads and lines without wasting more supplies than necessary.

DTF printers are designed to be used regularly. If ink sits too long, it can dry in the heads or lines and cause clogs, sometimes leading to expensive print head replacement.

The xTool Apparel Printer should stay plugged in so it can run its stirrer and light maintenance, but it does not automatically perform the same full cleaning routine that PrintGuardian can manage.

No. PrintGuardian helps reduce risk, but it does not replace normal DTF startup checks. xTool still recommends running a clean and printing a test page before production, such as at the start of each day.

The difference is that you can start that clean from the app before you walk over to the printer.

No. PrintGuardian does not affect the actual printing process or the artwork being printed. It uses the printer's own maintenance controls, such as wake, standby, and cleaning.

Because the M5 stays connected, we mute the printer's connection sound. We also recommend turning off oven auto preheat so automatic cleans use less energy and make less noise.

By default, the printer can print a test page after a clean. To avoid clogging the oven with extra pages, PrintGuardian turns that off for automatic cleans.

When you run a clean from the app, you can choose to print a test page. If the previous test page has not been removed, the printer will not print another one.

No. PrintGuardian monitors built-in printer status and counters, such as print count and seconds spent printing. We do not see the artwork, files, or designs you print.

No. The PrintGuardian M5 needs USB-C power 24/7 and should not be powered from the printer's USB-C port. Use a standard USB power adapter and USB-C cable.

The M5 has a built-in backup battery for outage detection. For that detection to work, the printer must go offline and Wi-Fi must remain available.

The printer should be on Ethernet or reliable Wi-Fi, and the M5 should be connected to reliable Wi-Fi. Bluetooth is only used during initial setup to get the M5 connected to Wi-Fi.

Yes. You can share a PrintGuardian-connected printer with another user as view-only access or full control, depending on what they should be allowed to do. You can revoke access at any time.

Yes. For the shaker oven, PrintGuardian can show current and target temperature, heating status, powder status, film motion, and feed, stop, or eject film controls.

For AP2-style air purifiers, PrintGuardian can show fan setting, fan speed, and filter levels. For the IF2 inline fan, it can show fan setting and speed.
