Thermal printer barcode height problem

Post by scottdrums89 »

Hello,

I just purchased the mini thermal printer from your site and am having some problems getting barcodes to print properly.

The result of the example script is attached - the CODE39 barcode printed but the UPC code only created one row of pixels.

When I change the text of the CODE39 barcode, it will also go down to a single row. I've tried different settings for setBarcodeHeight, but it seems to have no change other than adding the text under the row of pixels when set to 1.

Not sure if this is a bug in the code or a defective printer. Can anyone help?

Thanks,
Scott

Doesn't look good. I'm checking with our printer expert...

That's a new and strange one. I doubt it's the code, since it's been running as-is for a long time for a lot of people. Let's swap out the printer.

Email [email protected] with your order number and a link to this thread, we'll have a replacement on its way asap.
