HP1050C

Plotting 43meg file, portion of file is reaster image and the other is mostly text, on HP1050C, HPGL ver 17.0, Win driver 5.00-2195.2104, 33 x 44 inch paper size and only 3/5th's of the drawing plots, then the balance is a black line about one inch wide and then nothing else. File did print correctly when it was less than 30 meg. I also use advanced properties and select to plot from the computer and not from the plotter's memory.Same file prints correctly from ACAD 2000 when imported to another networked computer. Retry from intellicad prints with the large black line again! Any suggestion?
