A client of ours has had a semi-recurring (yet not able to replicate) problem with printers on their Citrix TS machines. Normally the first error is ""Print driver hosr for 32bit applications has stopped working"" followed by ""Unable to print SO_Invoice2.rpt"" or ""The handle is invalid."" I have bounced this around here in the past and I guess my question is, when printing through Paperless Office, does the system create an RPT image before creating the PDF? We have checked user rights and that doesn't seem to be the issue. Again, we can't make this happen on demand. It goes away for weeks and then pops back up. Usually the client can simple reboot the terminal and print.
