Record Summary Print Error

Record Summary Print Error

I have a Record Summary that prints out as an A4 label that is used in a warehouse to identify stock.

Each time the stock Qty is changed, a new label is generated.

This has worked perfectly for 18 months but today the view looks perfect but when I try to print the text is compressed and overlapping.

It is happening on different record configurations.

I haven't changed anything at all and the problem replicates on other PCs and printers.

I use Google Chrome.

Can anyone help?

Update:

I've temporarily got around the problem by removing the header and footer from the record - anybody got any ideas?
