and last two lines of text cannot print (leaving 62 printable lines). Adjust the top and bottom
margins in your document to allow for this.

The application machine emulation setting and the machine’s emulation do not match. Check in
the application software which machine you have selected to make sure the machine is set up
correctly. Remember that the machine emulates widely used machine selections:
HP Laser Jet 6P, HP Laser Jet 6P, Epson FX-850, IBM proprinter XL
Try setting the machine into HP emulation and then select the HP LaserJet 6P printer in the
application software.
