I am printing a batch of checks with a DOS based accounting package. Some of the checks print and some don't. Yet the software marks them as printed and I recieve no errors. I am using a Panasonic KXP 2023 dot matrix printer on my local LPT1 port. I have set the Spool Settings to "Start printing after first page is spooled" with EMF data format. Under the Port Settings button, the "Spool MS-DOS Print Jobs" checkbox is greyed out and is not selected. How do I enable this checkbox so I can select it? Should I print directly to the Port, and should I use EMF or RAW data format?

Thanks for the help.
