HEL P - Landscape printing greater than 128 characters giving errrors

HI,

 I am trying to print using the command
gslp -lqr -p/tmp/prntfl1 report2 
This is creating an error when the print file has more than 128 characters.

Is there a command to mention the max chars?  or any other solution to my 
problem

Thanks in advance
