Data transfer is carried out by observing the ACKNLG or BUSY signals. Data
transfer to the printer occurs only after receipt of the ACKNLG signal or when
the BUSY signal is LOW.

Data must be present a minimum of 0.5 microseconds before and after a mini-
mum 0.5 microsecond STROBE pulse. BUSY goes high before the end of the
STROBE signal and remains high until the end of an ACKNLG pulse of minimum
4 microseconds.
EPSON HP LASERJET EMULATION
Most Epson laser printers have
an
option to emulate the Hewlett Packard LaserJet
printer. Check your user’s guide to determine if your printer has this option,
which can be selected from the front panel of the printer. Be sure to save the HP
option selection into the
printer's
default settings so the HP option is always
loaded at power-on. The HP option provides increased capability including easy
font selection and portrait and landscape printing.
