Explanation
The most important factor to consider when upgrading a laptop's RAM is the architecture of the RAM, which determines the type, speed, and capacity of the memory modules. The architecture of the RAM must match the architecture of the laptop's motherboard and processor, otherwise the RAM will not be compatible or function properly. The architecture of the RAM includes the DDR generation (such as DDR3 or DDR4), the form factor (such as SO-DIMM), the pin count (such as 204 or 260), the voltage (such as 1.35V or 1.5V), and the frequency (such as 1600MHz or 2400MHz).
The other options are not as crucial or relevant for the RAM upgrade. The brand of the RAM does not matter as long as the RAM meets the specifications of the laptop and is of good quality. The CAS latency of the RAM is a measure of the delay between the memory controller requesting data and the RAM delivering it, and it affects the performance of the RAM. However, the CAS latency is not a fixed value and can vary depending on the frequency and voltage of the RAM. Therefore, purchasing RAM with the same CAS latency is not necessary or sufficient for compatibility. The laptop's BIOS settings are usually configured to automatically detect and adjust to the RAM upgrade, and do not need to be manually changed by the technician.

802.11 ax is a wireless networking protocol that supports both 2.4GHz and 5GHz devices, as well as backward compatibility with previous 802.11 standards. 802.11 ax offers higher data rates, lower latency, increased capacity, and improved power efficiency than previous protocols. It is also known as Wi-Fi 6 or High Efficiency Wireless (HEW). Reference:

Explanation
The most likely cause of the issue is that the page orientation is incorrect. The printer may be set to print labels in a different orientation than the orientation of the label sheet1.

If an application was previously running in a virtualized environment and is not launching after being installed directly on the base operating system, it's possible that the technician did not account for dependencies or configurations specific to the virtualized environment that are not present or are incompatible with the base operating system. This mismatch can prevent the application from launching properly.
