P RINTING FROM DOS
While your HP DeskJet 720C Series is primarily
a Windows printer, you can also print from a
DOS software program when you run the
program within Windows 3.1
x and Windows 95.
At the time of publication this capability was not
available in the Windows NT 4.0 environment.
To print from DOS:
1 Make sure the 720C driver is set as the default
in Windows.
2 Run the DOS application within Windows.
3 In the DOS application, select DeskJet 660C
or DeskJet 550C as the printer. (You might
need a driver for this, which you can obtain
from the software vendor.)
4 Print the document.
The print settings available for printing from DOS
are located on the
DOS tab of the HP print
settings box ✼ (see page 9 to find out how to find
the box). Settings located on the other tabs of the
box will not affect printing from DOS.
The following settings are available:
■ Paper Size. Select the appropriate paper size
in the
Paper Size box.
■ Character Set. Select the appropriate inter-
nal character set (emulated) in the
Character
Set box.
■ Form Feed. Request the printer to automati-
cally eject paper and re-initiate printing on a
new page by clicking the
Form Feed Timeout
check box. Specify the number of seconds it
should wait after the last batch of data has
been received before ejecting the paper by
either typing the number of seconds in the
Seconds box or by clicking the up or down
arrow to select a number.
