Dear Mohd
Are you using Windows or OSX?
If Windows, you will need to ensure that the correct printer driver is installed for this printer. You can download it from here: https://download.epson-biz.com/modules/dot/index.php?page=single_soft&cid=64&pcat=2&pid=7
In the printer setup (in Windows, not Hansa) make sure you set the correct paper type and dimensions. These should now be the default settings for Hansa, but if you have already done the page setup for your cheque document, you may want to remove the page setup and start again.
If you're using OSX I'm sure the procedure is similar, however I can't see that this printer is compatible with OSX - there is no driver for it anyhow.
Regards
Paul
