UDS follows several guidelines when designing reports. The amount of information that must be displayed determines the size of the report. If the necessary information can be displayed in portrait on your paper size it will. A smaller font size will be used until the type would be unreadable if made smaller. If the necessary information is too wide to fit portrait the computer will switch to landscape mode. If the required information is still too wide legal paper (8 by 14 inches) will automatically be selected in the printer. Your printer and print driver will determine how the commands are handled by your system. UDS makes it easy for you to get the information you must have.
