If you can get access to the PC on which this will run, you can print single labels from VFP. On the PC I create a second printer for the dot matrix that will have to continuous labels. Within that printer I define the user defined paper size as 1" by 3.5" (or 100 X 350 .o1 inches).

Now define a label format in vfp that uses that printer. Label form next 1 command in the program will print one label and the custom page size will prevent the annoying page up that was soo easy to avoid in DOS.
