Go to Tasks > Enter Checks and call up this check.  If the status is truly "Manual" that means that you indicated that the check had been already manually written. On one of the screens in "Enter Checks" there's a place where you enter the check number for a manual check.  A check status of "Manual" will not print. Only checks with a status of "Processed" will print.

thanks ! my cheque status is 'processed' !

Another reason for a "Processed" check no printing is that a bank account was assigned to the check, possibly because the bank was specified in the Pay Group, but when you choose to Print Checks, you select a different bank account than the account stored on the  processed check record.

I can't say for sure why this has happened to me, but I have gotten that error a time or two.  I can never find anything that I may have done differently; it's always the first check in the sequence and shows processed, and we only have one option for the bank account, so I know that's not incorrect.  If I go back to task>enter checks, reprocess the check and finish, then task>print checks the check will print with no problem everytime. 

Is it a new employee or one that has previously had checks printed?

Thanks Stacy ! will try and let you know.

'new' employee.
