DPI (Dots Per Inch) measures a label printer’s accuracy—how many ink/thermal dots it places per inch. More dots mean smoother edges, clearer text, and better graphic fidelity. Why does this matter? For labels, DPI directly affects text readability (especially small or dense fonts), barcode scanning success (blurry edges cause misreads), and overall professionalism. 203 DPI works for standard tasks like logistics labels or price tags, while 300 DPI is essential for fine details: medical test tube labels, electronic component tags, or high-end product logos. DPI also influences speed and cost—higher DPI prints slower and costs more. It doesn’t affect label durability (that’s down to printing tech and consumables), but it does enhance readability in harsh conditions like strong outdoor light. Understanding DPI helps you avoid overpaying for unneeded precision or settling for blurry, unusable labels. Click here to know more.
