Hello,
There seems to be a bug in the latest version of LAMMPS when using fix print with multiple variables, in which the first row of the output is either missing entries or some of the variables are not being substituted correctly. The attached sample script demonstrates this problem. Rows after the first are unaffected.
For information, when I run this script, I get the following output:
