Approximating for Zebra printing (i.e. A4ZPrinting) is a C# library to design, generate ZPL commands and print labels for programmers.
A4ZPrinting is an object oriented library that uses and extends SharpZebra (https://github.com/rkone/sharpzebra) to generate ZPL commands for Zebra printers. It is a library targeted at C# programmers who likes an object oriented way of thinking and working with ZPL. It's not meant for end-users as it is not a WYSIWYG editor that show how the final print looks like. However, you can copy the generated ZPL commands and paste it in http://labelary.com/viewer.html to get a preview of the final printout.
I got tired of trying to piece low level ZPL commands together to get a successful label printed. There were too many elements to juggle like the size of the labels, the printer's dots per inch or DPI, the exact x and y coordinates of the text fields and barcodes. On top of these, trying to ensure that the text fields and barcodes don't exceed the physical label dimensions and don't intersect one another.
First, it abstracts out the physical objects like your printer model and print labels. Then, it uses the Composite design pattern to create derived classes like text fields and barcodes (known as field classes). The field classes are placed inside a template class. The template class are applied onto a label class. And finally the label class are send to the printer class to generate the final ZPL commands.
This is a work-in-progress so if you encounter any issue or have a question regarding this library, you can drop me an email at c_h_o_n_g_d_a_m_o_n@g-m-a-i-l.c0m (remove the underscores and figure out the domain) although no guarantee I will respond fast.
Please goto the wiki page for detailed instructions on how to test out and customized the library to suit the zebra printer model and label type that you are using as well as to get the look and feel of the printout you wanted.
This library approximates the layout and design you have in mind, generating the ZPL commands and sending them to be printed onto labels. But like all approximations, it's not perfect. In the event that the layout and design is not exact or as accurate, at least, the generated ZPL commands give you something to work with instead of starting from zero. Tweak the generated ZPL commands to achieve your desired results. Lastly, if you tweak the C# code and got a more exact result, do email and send me the updated codes and I will incorporate them in the next version. Thanks and happy coding!
