What might be happening is when you select a form code other than 1, the associated printer (which is accessible to other users) may not be accessible to this Windows 10 user OR it is accessible but it cannot read the printer properties. In 4.05, Sy_ReportSetting did not include the WorkstationName field as part of the key therefore whatever PrinterName$ you see in that record is what it's trying to connect to and must be available / accessible for all users who print using that form code.
Perhaps in the end you need to create another Form Code just for this user. Also I assume the Windows 10 user default printer is not they Dymo.
