Fr?CodePudding user response:
What is the code128 auto?General barcode format is defined, such as code39 code93, code128, format may refer to relevant national standard, the format is fixed
Depends on the type of bar code width 1, draw the line width of the bar code 2, how many of your string
If it is too long can set the line width clip figure, general code128 not too wide, the same line width cases than code93 points wide, similar to code39
Specific how to draw, reference gb rules canvas painting by yourself

If you want to write their own CODE, to implement the CODE 128 yards of printed, reference FR in the source CODE directly, about the barcode part..If you just because the label paper is too narrow, or print area is too small. Can hold. There are two methods to solve.
1. Adjust the print "scaling factor", can make the printed barcode, accounting for less space, but, if it is too small, could scanners cannot properly identify..
2. Select the appropriate code system, overall speaking: 39 use most, but occupies a space, the biggest 128 yards, accounting for the space is little, if you print the content of the pure digital, and is double digit, so suggest you use code128 C code, take up the space of only 128 a, 128 b half yards of size..

That is to change the width of the small line,CodePudding user response:
Adjust barcode display scale attributes can shorten the length, but the small barcode gun could not identifyCodePudding user response:
The same problems and the original poster.Must use CODE128 AUTO.
CODE128C cannot meet the requirements, with letters.
Know the come out to solve it.
FASTREPORT inside without CODE128 AUTO options.
ZPL language command also didn't find that is a set of.

With q, CODE128 AUTO can really reduce the width, I've always wanted to know is how to implement, check a lot of information can solve
