LINEPRIN
If your Hewlett Packard LaserJet printer is printing the compressed
font with a relatively faint font, you may be able to darken it
by choosing PRINTER CONTROL CODES (option 8,A from the Main Menu),
Then select printer number 5 (or another printer number if you know
you use a different number.) Select "Compressed" and replace the code with:
027,040,115,112,056,046,053,118,048,084,027,038,107,050,115,055,072
(This was tested with an HP 2100 LaserJet but may work for other HP's)
