We can not print invoices. THey spool but do nothing else. No error messages either.

We can print invoices that have items with no bins. But invoices with bins we can not print.

Bill,

Do the crystal versions of the invoice print? Have you customized the built in invoice forms? I would imagine you've tweaked the form and damaged the fields related to bins (so that's why items without bins print ok, but those in bins don't). Try printing to a standard invoice form and see if it works. If it does, you'll need to make a copy of the standard form and modify it to meet your needs, being careful not to modify the bin fields.
