A. 1. Ensure that you are using high-resolution images for printing. Low-resolution images can result in grainy prints. 2. Check the printer settings to see if there are options for print quality. Set it to the highest quality available. 3. Clean the printer heads if you are using an inkjet printer, as clogged nozzles can affect print quality.

B. 4. If the issue persists, try printing from a different app to see if the problem is with Tiny Print or the printer itself.
