The HP 720c and 722c printers aren't officially supported by Shop-Pro.
Sometimes they work well - other times not at all - even for the same
person and without any special change that they made! However, here are
some tips which may help you.

HP DESKJET 720/722C SERIES PRINTERS - PROBLEMS PRINTING
FROM THE DOS SHELL IN WINDOWS 95/98
ISSUE: The HP DeskJet 722C / 722C printer is not printing from a DOS
application when accessed through a Windows icon or when shelled out in MS-
DOS (R). No error messages are generated on the computer and no lights
blink on the printer. Printing from within Windows 95/98 works fine.
1. If the DOS application will not print when accessed from the
application's Windows icon, try accessing the application through the MS-
DOS prompt. To do this:
a. Choose Start, Programs and select MS-DOS Prompt.
b. At the C:\ prompt, type the path to the DOS application and press ENTER.
c. Retry printing from the DOS application from here.
d. If unable to print from here, go on to step #2.
2. Try printing a directory from the DOS shell to verify that the problem
is not application specific. To do this:
a. Choose Start, Programs, then MS-DOS Prompt.
b. At the C:\ prompt, type DIR>LPT1 and press ENTER.
If the directory prints, contact the DOS program technical support to
verify the correct printer settings within the DOS program.
3. If the directory does not print, check the following settings:
a. Choose Start, Settings, then Printers.
b. Make sure that only one HP DeskJet 722C printer icon is installed. Also
ensure the printer icon name has not been changed. It must read "HP DeskJet
722C Series Printer." If more than one HP DeskJet 722C printer is
installed, remove all HP DeskJet 722C printer icons except the one labeled
"HP DeskJet 722C Series Printer." Highlight the extra icon, then choose
File and Delete to remove it.
c. Highlight the remaining HP DeskJet 722C Series Printer icon. Choose File
and look for a check-mark next to Set As Default. If there is not a check-
mark, highlight the Set As Default line and click once. If the check-mark
is already there, cancel the File menu by clicking once on any blank space.
The File menu will disappear.
d. Try printing the DOS directory again if a change was made above.
(Otherwise, proceed to step f.) If it does not print, delete the last
remaining HP DeskJet 722C icon. Choose Yes to delete the driver files if
e. Restart Windows and reinstall the HP DeskJet 722C series printer driver
by following the instructions on the diskettes. Make sure the printer icon
name does not change. It must read "HP DeskJet 722C Series Printer" and be
set as the default.
f. Choose File, Properties, then Details. Make sure the correct port and
printer driver are selected
g. Choose Port Settings. Ensure that the box labeled "Spool MS-DOS print
jobs" is checked. Choose OK.
h. Choose Spool Settings. Ensure that the box labeled "Enable bidirectional
support for this printer" is selected. Choose OK.
4. Try printing a directory from DOS again. If the printer still does not
print, type the following command at the C:\ prompt.
and press ENTER.
5. Try printing the DOS directory again. If the directory still does not
print, delete and reinstall the printer driver. (Refer to Topic document
#BPD02922 or HP First document #4035.)
6. Try printing the DOS directory again. If the directory still does not
print, contact Windows 95/98 technical support to verify that the LPT.vxd
file in Windows 95/98 is the latest version.
7. If possible, try installing the printer driver software on another
computer and try printing.
