Thank you, Jim. To make sure I'm understanding this correctly, I should modify the string to:
1. *27,"E",*27,"&l2a0o6d0e-216u216u0z66f" ?
...but use a value less than 216?
For what it's worth, we also tried using this string:
*27,"E",*27,"&a1L",*27,"&l-163U",*27,"&l0E",*27,"&l0Z",*27,"&l66F",*27,"&l7.38C",*27,"(s10.5H",*27,"&u6D",*27,"&l1H"
Using this string the output is no longer clipped, but it's misaligned, and not consistently across the page (i.e. some boxes need to be shifted right, others left; some up, some down). What's different about this string that prevents character clipping? It seems to contain the same commands as the *27,"E",*27,"&l2a0o6d0e-216u0z66f" string with some additions that affect the vertical positioning.
