I too had the same problem.  I found a solution that may or may not
work.  (If you have an epson or compatible, this should work)

When I had the problem, I checked the printer manual to see if there
was anything else I could send instead of a CHR(0).  Indeed 
There WAS!.  The printer would accept CHR(128) also!  This DOES
work in dBase III+.

Set Print ON
?? . . . +CHR(128)+. . .

instead of

Set Print ON
?? . . . +CHR(0)+. . .

Hope this helps.
