Libre Office macro used to format spreadsheet for printing wire labels on a laser printer.
A spreadsheet is used as sequential wire numbering with prefix or postfix characters is easily accomplished.
The wire labels are entered in a single column on one sheet which is then transferred by a macro to a second sheet in the specified number of rows and columns. The label sheet can be formatted precisely to the size and shape of the label sheet.
Labels are printed from the bottom of the sheet to the top as the sheet tends to shrink each time it is printed with the greatest error at the bottom of the sheet.
Both inch and metric measurement units are available, but metric is preferred as the resolution is much higher.
