User is trying to print a check in Core, but it does not print in the expected layout and size. The check printing is off and it is not aligning by the grid in Alignment.
The check alignment is something that needs to be tried and tested a few times till you get it right. In the Print Checks screen, you should check the Check Style being specified as well as the Alignment. It allows you to test print the check. You can print to a blank sheet of paper and hold up to your check vouchers to see how the alignment is. Each printer and check style can be different. You should also check the settings and options like scaling (should be 100 by default) and margins in the Print dialog.
