Printing control method, printing control device and printing device with printing data printed according to height of another blank space

A printing control device, comprising:

• a receiving module, which is configured to receive printing data;
• a first acquisition module, which is configured to acquire first printing format information of the printing data, wherein the first printing format information includes a first blank space height;
• a second acquisition module, which is configured to acquire paper-saving parameter information;
• a calculation module, which is configured to obtain second printing format information according to the first printing format information and the paper-saving parameter information, wherein the second printing format information includes a second blank space height;
• and
• a printing module, which is configured to print the printing data according to the second blank space height,
• wherein the first blank space height and the second blank space height comprise respectively any one or more of the following:
• first distance, wherein the first distance refers to a distance between a printing position and a cutting position;
• and when the margin-top included in the second blank space height is less than the first distance, retreat a printing paper, wherein a distance of retreating the printing paper is equal to the difference between the first distance and the margin-top included in the second blank space height, or
• determine whether a command to be executed is a paper output command;
• in the condition that the command to be executed is the paper output command, convey the printing paper by a second distance, wherein the second distance is equal to the sum of the margin-bottom included in the second blank space height and the first distance, or
• print a first line of characters;
• and print a second line of characters after controlling a printing paper to be conveyed forwards by a third distance, wherein the third distance refers to the line spacing included in the second blank space height.

A printing device, comprising:

• a printing mechanism, which is configured to execute a printing operation, wherein the printing device further comprises:
• a controller, which is configured to:
• receive printing data, acquire first printing format information of the printing data and paper-saving parameter information, wherein the first printing format information includes a first blank space height;
• obtain second printing format information according to the first printing format information and the paper-saving parameter information, wherein the second printing format information includes a second blank space height;
• and control the printing mechanism to print the printing data according to the second blank space height,
• and further comprising:
• a conveying mechanism, which is configured to convey printing paper;
• and
• a driving mechanism, which is configured to supply driving force to the conveying mechanism;
• wherein the controller is further configured to:
• determine whether a margin-top included in the second blank space height is less than a first distance, and to control the conveying mechanism to retreat a printing paper when the margin-top included in the second blank space height is less than the first distance, wherein the first distance refers to a distance between a printing position and a cutting position, and a distance of retreating the printing paper is equal to the difference between the first distance and the margin-top included in the second blank space height, or
• determine whether a paper output command is to be executed, and to control the conveying mechanism to convey the printing paper forwards by a second distance in the condition that the paper output command needs to be executed, wherein the second distance is equal to the sum of a margin-bottom included in the second blank space height and the first distance, or
• print a first line of characters, and to print a second line of characters after controlling the conveying mechanism to convey the printing paper forwards by a third distance, wherein the third distance refers to a line spacing included in the second blank space height.
