Zebra EPL no dithering option

[petec81]

Im using CUPS with PDF and zebra barcode printers. I have noticed that the printout comes with wiggly lines on the barcode. when i use a windows driver i have the option to turn the output to strict B/W so the issue goes away. I cant find something like that in cups. Any idea how this can be accomplished?

I had the same problem which was caused by the mandatory anti-aliasing in the pdftoraster cups-filter. See OpenPrinting/cups-filters#129

Setting to false (below) and rebuilding the filter sorted it for me. It needs to be optional. I have yet to explore https://github.com/michaelrsweet/lprint

• pr.set_render_hint(poppler::page_renderer::antialiasing, true);
• pr.set_render_hint(poppler::page_renderer::text_antialiasing, true);

• pr.set_render_hint(poppler::page_renderer::antialiasing, false);
• pr.set_render_hint(poppler::page_renderer::text_antialiasing, false);
