Barcode not showing up on screen or when printing

I have windows 7 and IE 11 Event espresso 4.6.16 and I can’t get the barcode to show up on the screen on when I print the ticket. I have changed the output_type to bmp but still no results. When I open the ticket up in FireFox it displays but is very large and takes up most of the screen. What am I doing wrong.

Hi Shon,

Can you post the barcode shortcode that you have input in the ticket editor so we can investigate?

Here is the bar code from my ticket
[BARCODE_* w=2 h=70 fsize=18 bgcolor=#ffffff color=#000000 output_type=bmp]

I am able to see the barcode now, now sure what changed but it just started to show up, however, it does not have any of the numbers below the barcode.

Thanks Shon

Hi,

The BMP output type doesn’t show numbers, removing that parameter or changing it to CSS, SVG or Canvas will enable the numbers.

One thing to keep in mind is CSS will not display a barcode on when printed, and some browsers do not display SVG or Canvas. A good cross browser solution is use two barcode types or the bmp and add the [RECIPIENT_REGISTRATION_CODE] shortcode to the ticket template.

OK so I the scanner and it does scan bar codes just not the ones out of event espresso. I think it is the black bars at the end of the image that should not be there. I have reversed the colors for that the background in white and the color is black and I get no image at all in any output type on any browser. here is my settings:

[BARCODE_* w=1 h=50 fsize=18 type=code93 color:#000000 bgcolor=#FFFFFF output_type=bmp]

[BARCODE_* w=1 h=50 fsize=18 type=code39 color:#000000 bgcolor=#FFFFFF output_type=bmp]

[BARCODE_* type_code=39 output_type=bmp]

Really need to have a solution to this issue ASAP. I have a conference that needs to open up this week and I need the ticketing issue resolved. Can I buy another support level to get faster response time?

Thanks,
Shon

Hi Shon,

The reason this code:

[BARCODE_* w=1 h=50 fsize=18 type=code93 color:#000000 bgcolor=#FFFFFF output_type=bmp]

is not working is due to the : before the hex value:-

color:#000000

This should be

color=#000000

So if you replace your code with this:

[BARCODE_* w=1 h=50 fsize=18 type=code93 color=#000000 bgcolor=#FFFFFF output_type=bmp]
[BARCODE_* w=1 h=50 fsize=18 type=code39 color=#000000 bgcolor=#FFFFFF output_type=bmp]
[BARCODE_* type_code=39 output_type=bmp]

Do you get 3 barcodes? 2 with a white background and one with black background?

Yes that worked. Thanks for all your help.

Your most welcome 🙂

However just to confirm, do those 2 barcodes now scan and the bottom one not?
