A print control device, printing system, and print control method can reliably execute desired operations according to the status of the printer. A print data receiving unit 81 receives print data including mode information from a host 20; a status acquisition unit 82 gets the status of a printer 32; a decision unit 83 determines if the mode information and the status of the printer 32 meet an execution condition; and a printer control unit 84 changes the printer 32 to a specific mode and sends commands generated from the print data to the printer 32 when the decision unit 83 determines the execution condition is met.
