CiviCRM Community Forums (archive)

We used civicrm's ability to print mailing labels recently, and found that the standard 5160 label format suffers from a small amount of label "creep".  The first label at the top is positioned correctly, but each subsequent label down the page moves up a bit because they are slightly short, until the last label at the bottom is printed halfway across the seam between the 9th and 10th labels.  Same thing happens horizontally, the labels are slightly too small and creep across the seams.
After some experimenting we figured out how to fix this by inserting spaces like {  } at the top and sides of the label formats in CiviCRM.  Is there a better way to deal with this problem?
We have not tried any of the other label formats.  The 5160 is the most common one for mailing addresses.
Thanks.

After testing on two different PCs, printers and brands of 5160 stock, it is clear that there is some variation due to hardware & labels.  However the following seems to work better in general.

Thanks very much for your pointer.
