Code128 Barcode not printing (again) ... #206

Open ctenov opened 1 year ago

ctenov commented 1 year ago

Hi Luke,

I know this was discussed in #31, #39 and #59 issues, but I think there is an error (again) on printing Barcode Code128 in version 3.0.0 applied on Windows C#. (If it does matter I am printing via Ethernet)

I did a little print of barcode 128 with original driver of printer Sweda SI300L and after that I printed a slight modification of your master sample of the library and you will see on the photo that Barcode 128 is not present when I used ESCPOS library.

I will paste below the code I used and the photo of print. Can you help me on this ?

Many Thanks

Barcode128

The problem was the length of the barcode data, if the barcode image is too large to be printed, the printer will just ignore it and not print the barcode.

@ctenov reported that the solution for him was to set the bar width to the thinnest possible (refer to command SetBarWidth). However he actually had to use the value 1 in the command which is currently not supported by this library enum, but there's a reason for that, EPSON's manual doesn't display 1 as an option for this command's parameter.

Another thing to keep in mind about the mentioned enum is that according to EPSON manual, the default value is not 4 as the enum states, but 3. image
