Print All Files After…

I use an expanded 64K version of ZX Pro/File to maintain a large mailing list of over 500 names. A problem that I have encountered is that my printer sometimes jams during a label run, and it always seems to happen at around the 400th file. After stopping the program and clearing the printer I have to restart ZX Pro/File from the beginning. The first 400 labels were fine, but there is no way to jump to the file where the printer jammed and just continue printing.
