>I still don't know of anyone who printed to a Zebra without trouble.

ME! The Japanese manufacturing company I worked for printed to Zebra printers at more than 20 workstations on two production shifts six to seven days per week for years. No issues.

Those printers are amazing for what they do. The ones we had were parallel ports, and we assembled a .TXT file to get it working exactly the way we wanted it (formatting, fonts, boxes, coloring, inverse coloring, etc.), and then read in those text files with macro portions (typically something %like_this%), and we would issue STRTRAN(lcText, "%like_this%", lcValue) on them in sequence to update with real content.

To print, we issued a DOS command: "copy file.txt lpt1:" using the RUN / ! command.

Worked beautifully. They printed around 500 labels (kanbans, which were about 3" by 5") per shift, 1000 per day, per printer. And as I say, they had 20 or so at the facility.
