Explanation

Point-of-sale (POS) receipt printers are almost universally thermal printers - they use heat to activate a chemical coating on specially treated thermal paper to produce text and images. They have no ink or toner. If standard, non-thermal paper is loaded, the printer will appear to 'print' (the mechanism runs and paper feeds) but the output will be completely blank because there is no heat-sensitive coating to react. This is by far the most common cause of blank receipts. Installing a new driver (B) or checking power (D) would not cause blank output on an otherwise functioning printer. Checking the default printer setting (C) is irrelevant to print output quality.
