since I am currently working exclusively in the home office and no longer have to do with labels professionally (only as a hobby), I can unfortunately no longer work on this project. But if someone would like to provide me a @Zebra printer, I would be happy to develop it further. Of course, pull requests are still welcome. ZPLGFA Golang Package convert pictures to ZPL compatible ^GF-elements The ZPLGFA Golang package implements some functions to convert PNG, JPEG and GIF encoded graphic files to ZPL compatible ^GF-elements ( Graphic Fields ). If you need a ready to use application and don't want to hassle around with source code, take a look at the ZPLGFA CLI Tool which is based on this package. install install Golang go get simonwaldherr.de/go/zplgfa example take a look at the example application or at this sample code: package main import ( "simonwaldherr.de/go/zplgfa" "fmt" "image" _ "image/gif" _ "image/jpeg" _ "image/png" "log" "os" ) func main () { // open file file , err := os . Open ( "label.png" ) if err != nil { log . Printf ( "Warning: could not open the file: %s \n " , err ) return } defer file . Close () // load image head information config , format , err := image . DecodeConfig ( file ) if err != nil { log . Printf ( "Warning: image not compatible, format: %s, config: %v, error: %s \n " , format , config , err ) } // reset file pointer to the beginning of the file file . Seek ( 0 , 0 ) // load and decode image img , _ , err := image . Decode ( file ) if err != nil { log . Printf ( "Warning: could not decode the file, %s \n " , err ) return } // flatten image flat := zplgfa . FlattenImage ( img ) // convert image to zpl compatible type gfimg := zplgfa . ConvertToZPL ( flat , zplgfa . CompressedASCII ) // output zpl with graphic field data to stdout fmt . Println ( gfimg ) } label server If you have dozens of label printers in use and need to fill and print label templates, this tool will help you: License MIT
