Add layout adjustment options: vertical/horizontal offset, label height, and scale.
This commit adds several new customization options to improve label alignment and output quality when printing QR code labels: - Introduced vertical and horizontal offset inputs to shift the entire label grid for fine alignment. - Added label height input to adjust the height of each individual label in millimeters. - Added content scale input to resize the entire label content (QR code and text). Also updated the UI to include explanatory text for each of these parameters, and added a summary paragraph to the main instructions describing how each setting affects the layout.

To fine-tune the label alignment for your specific printer or label sheet, you can adjust the following parameters:
|
||||
<strong>Vertical Offset</strong> moves the entire label grid up or down on the page, while
|
||||
<strong>Horizontal Offset</strong> shifts it left or right.
|
||||
<strong>Label Height</strong> controls the height of each individual label, and
|
||||
<strong>Content Scale</strong> resizes the text and QR code inside each label.
|
||||
The <strong>Show Border</strong> option adds a visible border around each label, which can help with calibration and print alignment.
|
||||
Use these settings to ensure the labels are printed accurately on your sheet.

One <strong>known limitation of this tool</strong> is that it
|
||||
<strong>only works on Google Chrome and possibly Firefox</strong>.
