• a converting unit that converts print data of the first print job to image data;
• an image-forming unit that forms an image based on the image data;
• a storage unit that stores therein a first log of receipt of the first print job and a second log of formation of the image;
• and
• a control unit that checks, after the first log is stored in the storage unit, whether an available space on the storage unit is equal to or more than a predetermined size, suspends receipt of the second print job when the available space is less than the predetermined size, and sends an error message to the host to notify the host of suspension of receipt of the second print job, wherein
