Error #3717 (Printer Code Modifier search failed) at print time
When trying to print, the user receives Error message 3717:
This is happening because of a printer code modification you've set in the BarTender document. You can find the printer code modifications by going to "File > BarTender Document Options". On the General tab, click the Action List button:
For this example, it's ZPL being replaced. The code says to replace a character using code set 0 (and older code set). This in particular replaces the 0 with ∅, aka slash zero. This is primarily a cosmetic change so that people can distinguish between 0 and O.
The problem in this instance is that the ZPL produced never had a regular ^CI0 code to begin with so the search/replace errored out. Removing the Action caused the error to go away.
More Information (optional)
Another option to not using printer code modifications is to use TTF to add a slash zero in: https://support.seagullscientific.com/hc/en-us/community/posts/216564207-Slash-Zero-Fonts
