We recommend to disable printer firmware updates

Ever wonder why printer manufacturers are so keen on firmware updates? They say it's to enhance printing speed, fix bugs, and ensure smoother operation. However, there's more to it than just improving your experience. Printer manufacturers release these updates to control your printing options and influence your purchasing decisions, it's no secret printer manufacturers make most of their profit from selling their own branded ink cartridges.

Just as your mobile phone or computer receives updates, printers also need periodic updates. While it's usually a no-brainer to update your phone or computer, you might want to think twice before updating your printer. These updates can render compatible cartridges useless, forcing you to buy their costly branded ones.

To safeguard your printing experience, disable automatic firmware updates in your printer’s settings. This will help prevent any disruptions.

By choosing to opt out of firmware updates, you can maintain the ability to use cost-effective compatible cartridges, avoiding the higher costs of branded ones. Remain alert for update notifications and decline them to preserve your options.

Since each printer varies, it's always advisable to consult your specific printer manual on how to disable firmware updates.
