Focus and source quality
Enough pixels do not repair missed focus, motion blur, aggressive compression or sharpening artifacts.

then test the right assumption.
Print failures often look similar even when the cause is different. Choose the symptom, answer the specific checks, and jump to the tool or guide that can confirm the next step.

When the file is not the only variable
A technically correct file can still produce a disappointing print.
Material and process
Paper texture, ink limits, printer calibration and finishing affect the result after the file passes numerical checks.
Display and viewing
Screen brightness, ambient light and viewing distance can change whether a print appears dark, soft or low contrast.
Provider-specific rules
Templates, profiles, bleed and accepted file formats can change by product. The written current specification wins.
