(A) Inkjet printers do not produce noticeably lower print quality than laser printers for standard office documents.
Print quality has nothing to do with servicing. NO
(B) Offices that use laser printers are not far more likely to operate them at substantially higher print volumes over time than offices that use inkjet printers.
Heavy usage could explain more servicing instead of lower reliability. If they are used heavily, the comparison would be unfair and conclusion is weakened. COREECT
(C) At least as many offices in the survey had acquired laser printers as had acquired inkjet printers.
The question is about percentages. NO
(D) Laser printers do not generally require longer periods of downtime for each service visit than inkjet printers do.

(E) Offices that acquired printing equipment within the past year are not far more likely to have chosen laser printers than offices that acquired equipment five years ago.
Purchase timing is irrelevant. NO
