Printing an image dynamically using ZPL
Posted 01 November 2012 - 08:47 PM
This question isn't directly related to ProIV but I'm hoping somebody here may have come across something like this already.
We currently have the ability to print to labels (using ZPL - Zebra Printer Language) in our system but have only ever printed text and horizontal/vertical lines. We simply call a logical report that displays the raw ZPL and direct the report to the label printer.
We have now been asked to incorporate a company logo on one of these labels. After researching the ZPL spec it appears as though this can be done one of two ways; either by loading the image (bitmap) onto the printer ahead of time and then calling it each time you print the label or by embedding the image in the label itself. The problem with method 1 is anytime the printer loses power you need to reload the image onto it. The problem with method 2 is that it makes the label company specific (each company would have to have their own version of the label). Just wondering if anyone else has run into this and, if so, how you handled it.

Mike are you sure the image is lost on power loss? We load images into Zebra printers without any power problems.
Thanks for the reply.
Must admit I haven't actually tried that yet so I don't know for sure. We're using Wasp printers and I haven't been able to find a way to load an image onto the printer without writing some ZPL code to do so. When you load the images are you using ZPL or do the Zebra printers allow you to load the image through the print driver or another utility?

There is a Zebra utility called Net Bridge which we use. We called Zebra support and they told us about it. It is a pay for product but they gave us a trial which has not expired and works fine. You simply import your image to the printer. With the paid version you can copy all settings, including uploaded fonts,etc. from printer to printer, which for any install with more that a couple of printers, will be required.
That sounds great. Hopefully Wasp has a similar product.
Thanks for the info.
