[Koha] Printing Spine Labels in Koha 3.2

Greetings! I am new to Koha (this is my second week using it) and am thus new to printing spine labels using Koha. I have run into some label printing problems, and would greatly appreciate any words of advice from those of you who have sucessfully printed spine labels. Some background: I use DEMCO WS14217670 labels (8 1/2 x 11 sheets of 1" x 1.5# labels). The first three columns are perfectly aligned and centered. The last four columns of label data are not; they need to be shifted to the right, but I am at a loss as to how to do so. Any suggestions, ideas or advice would be most welcome! Thank you in advance, Sharon Reidt Technical Services Specialist Marlboro College Marlboro, Vermont, USA
