This page covers the basics of how to print a check, and also the print alignment and other features found under the Merchant - PDF Settings menu.
NOTE: The moment you click on the Print icon - which you do to view and print a check - the icon changes to grayscale. This feature can be used to indicate which checks you have already viewed and presumably printed.

Error When Clicking the Print Icon: If you are using Internet Explorer and receive an error when clicking the Print icon - please see this page.
Obviously, checks are very highly formatted. Certain data must be placed in exact locations. There is a setting in the Print Dialog box of Adobe that can alter the correct placement of this data. When the Adobe Brpwser helper launches the document into your browser, the Adobe toolbar will appear just above the actual check document.
Click on the Print icon on the Adobe toolbar - not the Browser's Print icon. That will launch the Adobe print dialog box (see image below). On the bottom right area of the dialog box for older versions of Adobe Reader, there is an option for "Shrink oversized pages to paper size." Make sure that option is UNCHECKED!. Adobe should remember this setting for future printings - but it is a good idea to double check each time you print a check. Newer versions may have the option for Page Scaling in a drop-down box. Make sure that is set to None.
On some printers, using the Auto-Rotate and Center option in the Adobe print dialog does the trick, on others - it throws everything way off. Again, depending on the printer you use, you may have to play with the settings to get the positioning within acceptable margins.
Also, depending on your printer, you may receive a warning that certain areas of the page are outside the printable margins. Ignore all such warning and select the option to continue.
However, because all printers and printer drivers vary, the above settings may not put the critical MICR line where it needs to be. Or, due to the way the printer grabs the paper, the entire PDF image may print too high or too low.
The Merchant - PDF Settings menu allows you to fine tune the exact placement of the PDF image to your exact printer by adjusting it up, down, left or right by increments of 1/100th of an inch.
See the PDF Settings page for complete instructions on adjusting check printing and select the size and number of checks per page.
