The short answer is: no. Manufacturers are not allowed to legally require any printer owner or lessee to exclusively purchase supplies from them. If a representative of the manufacturer threatens to void the machine warranty, or charge for a service call because you are using a compatible supply, request their statement in writing. They are not allowed to demand verbally or otherwise that you buy their supplies. This "tying agreement" is not lawful and violates provisions of the Sherman and Clayton Antitrust Acts as well as the Magnuson-Moss Warranty Improvement Act.
In 1936, the Supreme Court set a precedent by ruling IBM was not allowed to terminate a customer's data processing machine lease just because the customer was using tabulating cards from other manufacturers. The more recent Magnuson-Moss Warranty Improvement Act title 15, Section 2303 specifically prohibits a manufacturer from conditioning a written or implied warranty on the use of its own brand product except under very restrictive circumstances.
