An image processing apparatus includes a memory, a receiving unit, a detector, a generation unit, a determination unit, and an alert unit. The memory stores output characteristic information, information on image output characteristics of a printer, which is specified for output. The receiving unit receives a print command. The detector detects a one-dimensional code in accordance with a received print command. The generation unit generates print data in accordance with a received print command. The determination unit determines, in a case where a one-dimensional code has been detected, whether or not a printer, which is specified for output, is capable of printing the one-dimensional code with a predetermined print quality or higher by referring to the stored output characteristic information. The alert unit issues an alert in a case where the printer is incapable of printing the one-dimensional code with the predetermined print quality or higher.
