Due to a new EU law every food packaging label has to outline possible allergy-causing ingredients by either styling them bold or underlined in the ingredients list.
Currently I'm printing my labels via ZPL to zebra printers. I checked the ZPL manuel 1 & 2 and didn't find way how to print something in bold or underlined. Is there any way to do this?
Example: "Ingredients: water, sugar, milk, cheese, chocolate"
SHOULD BE NOW: "Ingredients: water, sugar, milk, cheese, chocolate"
My current label code for the ingredients is:
^CF0,15
^FO13,245
^FB530,2,,L,
^FH^FD__VAR_INGREDIENTS__
^FS
Thank you very much for your help,
Stefan
To underline - use a monospaced font like AA,AC,AD,AF or AG
Use
^FO350,50^AGR^FDwhatever,milk,butter,salt^FS
^FO340,50^AGR^FD ____ ______^FS
where the underline here is under milk and butter, you can adjust the offset by trimming the FO
's X and Y positions by a few dots (10 X here)
On further investigation, I found
To bold
Use an old dot-matrix-printer trick. Still using fixed-pitch font, reprint the text but replacing the non-bold characters with spaces and adjust the X-position by 1 or 2 dots, reprint again with the Y-position adjusted by 1 o2 2 dots.
^FO350,50^AGR^FDwhatever,milk,butter,salt^FS
^FO348,50^AGR^FD milk butter^FS
^FO350,52^AGR^FD milk butter^FS
To underline, draw a graphics box below the required letters. This is relatively easy to calculate since the width of each letter is constant.
^FO345,490^GB0,160,4^FS
^FO345,690^GB0,240,4^FS
I tested using an A300 and 8"*3" labels, so I needed to rotate the text, hence some odd calculations. The manual does not show the ^FS
, even in the examples but I found it was required.
