Patent ID: 7738800

Claim:
A printing device comprising: a printing module which executes printing of a print data instructed to be printed on a printing medium using printing material with a set print density; an amount detecting module which detects a remaining amount of the printing material; a first value determining module configured to determine a maximum value of a density range within which a print density is to be set for printing, wherein if the amount detecting module detects that the remaining amount of the printing material is equal to or less than a predetermined amount, the maximum value is determined to be a value smaller than a maximum value of the density range for a case where the remaining amount of the printing material is larger than the predetermined amount; a density judging module configured to judge whether a print density currently set for printing of the print data is greater than the maximum value determined by the first value determining module; and a print density changing module configured to change the currently set print density for printing to be equal to or less than the maximum value determined by the first value determining module if the density judging module judges that the currently set print density for printing is greater than the maximum value determined by the first value determining module, wherein the printing module executes printing of the print data with the changed set print density changed by the print density changing module.
