Does each printer work at the same pace?

Let r = documents per hour for 1 printer.

4r%2A6=40, according to rate%2Atime=HowManyDocuments.
r=40%2F%284%2A6%29
r=10%2F6
highlight%28r=5%2F3%29 documents per hour, from 1 printer.

For the question part, the same four printers is implied.
4%2A%285%2F3%29%2A4=HowMany
As a meaningful whole number, only 26 documents.
