Wow, thanks everyone for your replies - I wasn’t sure if I would get any!
We were running v15 server in 64-bit mode (clients were 32-bit of course). We changed some of the web processors to pre-emptive, no change. Will ask the developer to answer some of the more technical questions you asked. Some good suggestions - thank you. It is just strange that we don’t have the problem when we print to the Xerox printer (although it is a slow printer, at least only the 1 user is waiting). Current server is an iMac Pro, but we can reproduce the problem on a late-2013 Mac Pro. The reason we have the server do the printing is because we have people pick orders using iPads with barcode scanners. When they have finished picking, the server processes the order and prints out the invoice and packing slip. Thanks again for all your help.
