In PB, I have a print feature to print a string directly to a Zebra label printer.  The string includes Escape characters with formatting commands. It works great in my PB app.

ll_job = PrintOpen("Label",TRUE)
li_rc = Print(ll_job, ls_ZPL)
li_rc = PrintClose(ll_job)

I'm just wondering if there's a C# equivalent?  I'd like to write an independent C# program to print labels.

Hi Tracy,

There's not an "equivalent" in the sense that you can get a print out by only specifying 3 lines of code. However, it is definitely possible to print in C#, however the process is a bit more involved (how involved depends on the approach you take) and you won't be able to get through it without writing C# manually.

 

The following is an old tutorial that makes the process as simple as can be:

Hopefully it can help you measure more or less how not-as-easy it is.

 

Regards,
Francisco

Thanks for your response Francisco. Unfortunately, the tutorial your shared causes the string to print as a drawing object, which is standard practice with modern printers. Everything is a graphic. I need to send the raw string as the Zebra printer only receives a string with a start sequence (^XA) and an end sequence (^XZ), Then it parses everything in between for label formatting commands. The data for the label is embedded in the string.

If the printer can be accessed through Serial protocol you can do that relatively easily in C#
