There is nothing special you have to set up inside Sage 100 Contractor to be able to print checks. However, sometimes you have to modify the check form to print the information to align with the pre-printed check forms. Sounds like it is just a printer issue, and your IT people should be able to figure it out. Note: you did not explain the exact problem, so its hard to determine what the issue is. If the printer is really old, I would just by a new one.
