The
HQ
Drivers
"high"
squeezes
the
highest resolution out of
your
printer. A higher print
density
on
9
and
24 pin printers is unattainable. 9 pin printers
reach
an
unreduced
resolution
of
240
x
216
dpi
using
six
passes, and
24
pin printers
attain
360
x
360
dpi using four
passes.
The
difference between
"med"
and
"high"
is
not
that
drastic.
We
recommend
"high"
only
when
uncompromised
print quality
is
demanded, as it requires
the
longest printing
time.
The print
ribbon
should
not be brand
new,
or
your printout
may
smear.
Printer Type Specifications
Following
the
degree
of
quality
tenn is
the
abbreviation
for
the
printer type,
which
is
usually
"Eps".
Drivers
with
this
name
work
with
just about
every
printer
(9
and
24
pin).
24
pin
drivers
for
high
resolution are
named
"NEC"
or
"EpN".
"EpN"
drivers
only
work
with
newer
Epson
printer
models
(not
LQ400).
The
"NEC"
drivers
work
with
NEC
and
nearly
all so-called
Epson
compatible
24
pin printers. The
"IBM"
drivers are for those rare
IBM
compatible printers
(MPS
1000
parallel).
Only
parallel
IBM
drivers are
contained
on
the
disk. Drivers
for
exotic printers
such
as Star
SG
are also
available.
Other drivers,
such
as
for
color printers,
are
in
developmenL
Connection Specifications
The
fmal
specification listed
in
the
driver's
name
indicated the type of
connection.
Here
you
will
find
the
abbreviations: "Sl", "S4", "S5", "S7",
and
"GC".
The "S" stands for serial connection
and
is followed by
the
secondary
address
used
by
the
driver.
This
is
very
important with
serially
connected
printers,
as
a
wrong
secondary
address
leads
to a
useless
printout!
This is
the
reason
why
many
of
the
drivers
contained
on
the
GEOS
System
disks do·not
work
with
some
serially connected printers.
The
Perfect
Pririt
HQ
drivers
solve
this
problem
by
offering printer drivers
for
all
commonly
used secondary addresses. The next section discusses which secondary
addresses
to
use
with
the
various
printers
and/or
interfaces.
All
serial
drivers
use
the
device
number
four.
If
yom
printer is set for
device
number 5, please switch it
to
4
to
use
it
with
any
of
the
drivers included
with Perfect Print.
If
you
have
a
specifIC
need
for
serial
drivers
which
use
device
number
5, contact
CMD
Technical
Support.
The abbreviation
"GC"
indicates a driver
which
has
been
written
to
use
a
parallel printer directly connected
to
the
user port of your
computer.
These
drivers are
the
fastest due
to
the
higher transfer rate of data between
your
computer and printer. Historically
"GC"
stands·.for
"geoCable"
which
was
produced
by
Berlceley
Softworlcs,
but
many
other
cables
have
been
produced
by others
which
are
compatible.
For
more
information
about parallel
cables
and
connections,
see Section
7.
