Abstract

A system comprising a processor and a memory comprising firmware is provided. The firmware is executable by the processor to cause the processor to operate a print mechanism in accordance with a first state associated with a capability of the print mechanism, change the first state associated with the capability to a second state in response to receiving first information from an external interface, and operate the print mechanism in accordance with the second state associated with the capability.

Claims

1. A controller for performing a hardware related process for a printer, the controller comprising:

at least one interface to first pens of a print cartridge for implementing a first printer related process on a print medium, second pens of the print cartridge for implementing a second printer related process on the print medium, and a memory configured to store a first capability indicator corresponding to the first pens of the print cartridge and a second capability indicator corresponding to the second pens of the print cartridge, wherein the first pens of the print cartridge are configured to be operational according to the first capability indicator being in a second state allowing the first pens of the print cartridge to be operational before a state changing verification, wherein the second pens of the print cartridge are configured to be inoperable according to the second capability indicator being in a first state disabling operation of the second pens of the print cartridge before the state changing verification is received for changing the second capability indicator to a second state enabling operation of the second pens of the print cartridge;

wherein the printer comprises the first pens of the print cartridge and the second pens of the print cartridge; and

wherein the second pens of the print cartridge are initially configured to be operable on the printer and then subsequently disabled on the printer;

wherein the controller is configured to;

control an operation of the first pens of the print cartridge and the second pens of the print cartridge according to the first state and second state of the first capability indicator and the second capability indicator, respectively;

receive the state changing verification from a server authorizing operation of the previously disabled second pens of the print cartridge; and

in response to receiving the state changing verification, change the second capability indicator from the first state to the second state, the second state corresponding to the operation of the second pens of the print cartridge being enabled in response to the verification received from the server.

2. The controller of claim 1, wherein the second state enabling operation of the second pens of the print cartridge is set to expire at a time identified in a license.

3. The controller of claim 2, wherein the set expiration time identified in the license corresponds to a trial period.

4. The controller of claim 2, wherein the trial is a predetermined number of uses of the second pens of the print cartridge.
