If someone has an issue with the printer how to fix it?

Your question is stated in an extremely confusing manner, but what I think I understand is that 1) you're developing a hardware product, and 2) you need to pay someone to write code for it, but 3) you're nervous about outsourcing the code development outside the US because you don't want someone else to copy you? Let me know if that's accurate, and if not, please state your question more clearly so I, or someone else can answer it correctly. best, Lee

ECC memory can provide benefits for non-server applications, but it is generally not necessary in most cases. Here are some key points: ECC memory can detect and correct single-bit errors in memory. This improves data integrity and stability. Without ECC, single-bit errors can potentially cause crashes, data corruption, or other issues. For most desktop and laptop usage, like web browsing, document editing, media playback, etc., the risk of encountering memory errors is very low. ECC would provide little practical benefit in these scenarios. Systems are robust enough to handle occasional errors without issue. ECC becomes more important for tasks that involve large memory usage, data-intensive workloads, or applications where data integrity is critical. Things like video/photo editing, 3D modeling, code compilation, database usage, etc. could potentially benefit from ECC's error correction. ECC is virtually mandatory for servers and other mission-critical systems where uptime and avoiding data loss are business-essential. But for average home or consumer use, the extra cost of ECC RAM is generally not worth it given the low error risk. Newer memory technologies may make ECC less critical over time as memory reliability improves. But it remains best practice for applications where correctness is paramount over absolute maximum performance. ECC can provide benefits to data integrity on non-server systems used for intensive tasks. But for general desktop or laptop use, the low error risk means ECC is not usually necessary from a practical standpoint. It's beneficial where accuracy is mission-critical.
