newspaper sheets; newsprint; newspaper used for wrapping or packing
Refers to newspaper as paper material: sheets used to wrap, protect, cover, clean, or pack things. The reading しんぶんがみ is particularly natural for this practical-material sense, though しんぶんし is also used.
Means a newspaper as a printed physical object. When simply referring to the publication or daily news source, 新聞 is more common; this sense is restricted to the reading しんぶんし.
