The user inputs a plurality of print characters constituting the print content in the print content input area 121c, and selects a print font in the font selection area 121d and a print direction in the direction selection area 121 e. In the present embodiment, as shown in fig. 5(b), the user has input 7 print characters, i.e., the zip code "1234567", as the print content, the selected print font is "bold", and the selected print direction is "lateral print".
In addition, the print input screen also has a template new button 121g for the user to select a new template. If the size and position information of the actual print frame for printing the characters input by the user is not stored in the template data storage section 11, the user can also obtain the size and position information of the print frame by external inquiry or by measuring the information himself/herself, and then create the template by the template creation button 121 g. When the user selects the template new button 121g, the input display section displays a template new screen 124 for allowing the user to input a template name corresponding to a print frame group to be newly created, the number n, height H, width W of print frames in the print frames, and coordinates X of each print frame1,X2,...Xn。
When the user presses the confirmation button 121g to confirm the information including the print font, the print direction, and the print content selected and input on the print content input screen, the print font identification unit 14 identifies the print confirmation font that can be confirmed by the user by printing the print character in the corresponding print frame, based on the print font and the size of the print frame.
The print font size determining section 14 includes a maximum font size acquiring unit 141, a preview image generating unit 142, and a font size setting unit 143.
The maximum font size acquiring unit 141 acquires the maximum font size that enables the print character to be printed in the corresponding print frame, based on the print frame height H, the print frame width W, the print font, and the predetermined font size reduction rule.
For example, for "template 1" selected by the user, the maximum font size acquisition unit 141 first acquires the height H of the print frame from the template name "template 1" selected by the user1And width W1(ii) a Then according to the height H of the printing frame1Calculating a font size which can be printed in a corresponding printing frame in the height direction of the printing character as the maximum font size to be determined, and the height H of the printing frame1In mm, the size of the font size in inches is the font size divided by 72, and 1 inch is 25.4mm, so the calculation formula for the maximum font size to be determined is as follows:
Figure BDA0002515593840000081
determining the width of an actually occupied area corresponding to each printed character according to all printed characters, printed fonts and the maximum character size to be determined; further judging whether the widths of the occupied areas of the respective printed characters are smaller than the height H of the print frame1。
If the word size is judged to be the maximum word size, the maximum word size to be determined is set as the maximum word size.
If not, reducing the maximum character size to be determined according to a preset character size reduction rule, taking the reduced character size as a new maximum character size to be determined, determining the width of the occupied area of each printed character according to the new maximum character size to be determined, and then judging again until the widths of the occupied areas of the printed characters corresponding to the maximum character size to be determined are smaller than the width W of the printing frame1And setting the undetermined maximum character size as the maximum character size. Wherein the predetermined word size reduction rule is: each time the judging module 141c judges no, 0.5pt is subtracted from the maximum word size to be determined.
The preview image generating unit 142 generates a maximum font size preview image formed when the print characters are set in the corresponding print frame, from all the print characters, the print font, the maximum font size, and the size of the print frame.
FIG. 6 is a diagram illustrating a print font size confirmation screen according to an embodiment of the invention. Fig. 6(a) is a schematic diagram illustrating a maximum font size preview image displayed on a print font size confirmation screen according to a first embodiment of the present invention. Fig. 6(b) is a schematic diagram of the preview image of the current font size when the print font size confirmation screen displays a reduction ratio of 40% in the first embodiment of the present invention.
As shown in fig. 6, the print font size confirmation screen 122 includes a preview image display area 122a, a reduced scale setting area 122b, and a scale confirmation button 122 c.
As shown in fig. 6(a), once the maximum font size preview image 122d is generated, the input display unit 13 displays the print font size confirmation screen 122 and displays the maximum font size preview image 122d on the screen to allow the user to confirm whether or not the maximum font size preview image satisfies the print request, that is, whether or not the maximum font size corresponding to the maximum font size preview image 122d is used as the font size for printing.
When the user confirms the maximum font size preview image 122d (i.e., presses the scale confirmation button 122c), the font size setting unit 143 sets the maximum font size as the print confirmation font size.
If the user is not satisfied with the size of the characters in the displayed maximum font size preview image 122d, for example, feels that the characters are too well supported in the print frame and wants a margin between the characters and the frame to be large, the reduction ratio of the print characters can be set by the reduction ratio setting area 122 b. For example, in the present embodiment, the reduction ratio is set to "40%".
Upon the user confirming the reduction ratio after inputting the reduction ratio (i.e., pressing the ratio confirmation button 122c), the font size setting unit 143 acquires the font size of the maximum font size multiplied by the reduction ratio as the current font size, and the preview image generating unit 142 generates the current font size preview image 122e corresponding to the current font size. As shown in fig. 6(b), the input display unit immediately displays a current font size preview image 122e in the preview image display area 122a of the print font size confirmation screen 122, and allows the user to confirm whether the current font size preview image 122e satisfies the print request.
If the user confirms the current font size preview image 122e, the font size setting unit 143 sets the current font size as the print confirmation font size; if the user is not satisfied with the current font size preview image 122e, a new reduction ratio may be set in the ratio setting area 122b again, and the process of acquiring the current font size preview image 122e may be repeated until the user confirms the displayed current font size preview image 122e and the font size setting unit 143 sets the print confirmation font size.
The occupied area determining section 15 determines the height and width of each print character occupied area from the print font and the print confirmation font size. The characters generally have certain margins on the upper, lower, left and right sides, the margins and the characters form occupied areas actually occupied by the characters, the heights of the occupied areas actually occupied by the characters with different fonts under the same font size are equal, but the widths of the occupied areas may be different, for example, the width of the occupied area with the number 1 is obviously smaller than that of the number 2.
Because the height of each print character occupation area is equal and the width of different print character occupation areas is different, the height of the print character occupation area is h and the width is wi，i∈(1,2,...n)。

The housing of the hand-held printer 2 is provided with a reference line 2a, which reference line 2a may be a raised line or a printed line, on the side perpendicular to the face with the print head. The reference line is parallel to the ink ejection array 26a and has a length equal to D, which is G, for indicating the position of the printing head and the length of the ink ejection array 26 a. Before printing, the user presses the hand-held printer 2 onto the medium so that the reference line conforms to the left or upper edge of the leading print frame in the print frame group and the center of the reference line is aligned with the center of the left or upper edge of the leading print frame, thereby aligning the inkjet array 26a with the left or upper edge of the leading print frame.
The sensing unit 27 senses whether the side of the handheld printer 2 having the print head is pressed against the print medium by the user and whether the handheld printer 2 is slid by pressing the handheld printer 2 against the print medium by the user. The case of this sliding is whether the handheld printer 2 has slid a certain distance.
