Are you trying to print 33 lines of a file, or trying to set the printer to 33-line mode?

If you want to print 33 lines of a file, there is no easy way to do that in DOS or using batch commands - you have to use a 3rd party utility or write a little qbasic script.

If you are just trying to send data to the printer, the easiest way is to redirect the ECHO statement.

for instance, assuming your printer is on the first parallel port:

ECHO This is a test > LPT1

Will print "This is a test" to the printer. You would have to look up the control codes for the printer to get the 33 line setting, but from that point it should be as simple as echoing the control characters into the printer.
