Problem encountered during Check Printing

I have encountred a problem during posting a payment journal through Bank A/c and selecting “Bank Payment Type” as “Computer Check”. After giving required information in the payment journal line and before posting, when I want to view the report from clicking the “Preview” button under “Print Check” option, it throughs an error stated as “Preview is not allowed”. But printing of the above mentioned check will be executed fine. In addition, when I want to post the entry along with “Check Printed” option as “Yes” it will not allow me to post the entry. It throughs an error giving “Check Printed must be No in Gen.Journal Line…” Please let me know the exact solution.

Hi, Print preview is not allowed in the Check Printing report. (Some validation is written in that report).
