On behalf of the Community Support Team, I'd like to extend a warm welcome back, Baylight. Your participation contributes to the discussions and exchanges making this forum a valuable space for everyone. Let me provide you with some information to guide you towards the appropriate support resources.
Since you have carefully followed the troubleshooting steps provided by Ren2216 for resolving the printing issue, yet you're still encountering the same thing, and given the issue isn't isolated to QuickBooks and is affecting other applications on your MacBook Air as well, this suggests a more systemic issue, relating to your printer or its configuration.
In this case, I recommend consulting your printer service providers for further assistance. They have specialized knowledge and tools to diagnose and resolve issues affecting your printer's performance across multiple applications. Additionally, they may be able to guide you through more advanced troubleshooting steps or suggest solutions tailored to your specific printer model and operating system.
Regarding your first two questions, I highly recommend keeping in touch with an IT Specialist. These professionals have the knowledge and experience of troubleshooting and resolving various technical problems. They can help you navigate complex software configurations, ensure your system is at peak efficiency, and provide valuable insights about the best practices.
