  If you check the header option the import will skip the first line of the input.

• How do i use the Scanner ?
• By clicking Scanner in top menu or scan under input field you will start the scanner.
  
  You'll have to give permission to the web page to use your camera to use the scanner.
  
  It is recommended to use the scanner on your phone in portrait mode.
  
  The scanner is very useful for creating copies of barcodes when you need more or just when you need to see what data the barcode contains.
  
  By pointing your camera at the barcode, the system will detect the barcode type and number.
  
  It is necessary that there is good light in the room and the barcode is bright for successful scanning.
  
  You should try to adjust the camera so that the picture is clear and crisp. You may need to move it around a little to get the right position. Sometimes it helps if you move the camera slowly away from the code to get the scan.
  
  After successful scan you can add the code directly to the input list of the codes by pressing the Add button.
  
  
• How do i create automatic barcode sequence ?
• To create an automatic sequence of barcodes please click the "0-9" button and fill out the requested numbers.
  
  Prefix -text or number added at beggining of each code
  Suffix -text or number added after each code
  Start-Stop -the range of number to generate the sequence.
  Step - the increment used after each barcode
  Length - the generated numbers will be at least this long, padded from left by 0 digits
  Label - if checked, will automatically add label for each generated number
  
  Example:
  Prefix 00 Suffix 11

  Step 2
  Length 4
  
  Will generate numbers from 0001 to 0009 and add 00 prefix and 11 suffix to each code
  
  These numbers will be generated:
  
  00000111
  00000311
  00000511
  00000711
  00000911
  
  

• How do i adjust the visuals / dimensions of the barcode ?
• You can adjust the visual settings in the Barcode section, the next section after where you input the barcode numbers. 
  
  The most important setting is size which defines the size of the barcode. By using the slider you can adjust from smallest to largest and the size should follow the specifications for that barcode type.
  
  DPI setting sets the quality of the print and the resolution of the resulting barcodes. 300 is the standard. 600 is higher quality.
  
  You can also define the margin around the barcode. The margin is defined in the units selected after it - either mm or inches. This unit setting also affects other length settings at the site.
  
  Next to the DPI setting, you can also set the colors of the barcode and rotation.
  
  You can click Text to adjust the text display options. Text defines the font and size used for barcode numbers. And label settings define how the text labels look. Before each option is a checkbox which you have to check if you want to display the barcode number or label. After clicking Text/Label you can adjust font size, font type, color. For Labels you can additionaly set if the label should appear below or above the barcode.
  
  
• How do i download the barcode image ?
• You can download the barcode image under each generated barcode by selecting the download format - PNG, SVG
  
  PNG - download as png image, this is the most used image format for general use.
  SVG - vector format which can be freely resized
  
  You can also dowload all the barcodes in .ZIP file in the download all section above the first barcode.
  
  Additionaly you can copy the image to clipboard for pasting in other programs like Excel. Please see other section about copying to clipboard.
• How do i print the barcode image ?
• You can print either individual barcode by clicking print button under it or if you have entered multiple barcode numbers you can print all by clicking Print All button under the generate button.
  
  First you have to select paper size like A4 and printing mode.
  
  Then there are 3 print modes supported in the print settings:
  
  1. # Copies - prints X copies from each printed barcode.
  2. Full Page - for each printed barcode prints full page.
  These two modes allow you to set margin size and if you check border setting it will draw a border around each code - this is good for example for cutting the barcodes.
  
  3. Label Sheet - prints X or full page of copies on predefined label sheet paper. For example on self adhesive label paper. 
  The sizes of the labels must exactly match the type of label sheet you are using.
  
  Label Width/Height - the dimensions of 1 label. By clicking Set # you can set the number of labels in each direction and the software will calculate the label width/height automatically based on the current paper size.
  
  Label Gap - horizontal/vertical gap between all labels
  Margin Left/Top - margins of the page left/right, top/bottom
  
  In all 3 modes you can see how many barcodes / pages will be printed.
  
  We suggest you try printing small amounts of barcodes to test if they are working first.
  
  After you setup the settings for printing you must click print to bring up the system printing dialog. In the browser print dialog it is necessary to select the correct paper size again and use zero margins.
