HP DESKJET 820C SERIES PRINTERS - PROBLEMS

PRINTING FROM THE DOS SHELL IN WINDOWS 95

ISSUE: The HP DeskJet 820Cse / 820Cxi 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 works fine.

SOLUTION:

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 820C printer icon is

installed. Also ensure the printer icon name has not been changed.

It must read "HP DeskJet 820C Series Printer." If more than one HP

DeskJet 820C printer is installed, remove all HP DeskJet 820C

printer icons except the one labeled "HP DeskJet 820C Series

Printer." Highlight the extra icon, then choose File and Delete to

remove it.

c. Highlight the remaining HP DeskJet 820C 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 820C icon. Choose Yes to delete the

driver files if prompted.

e. Restart Windows and reinstall the HP DeskJet 820C series printer

driver by following the instructions on the diskettes. Make sure

the printer icon name does not change. It must read "HP DeskJet

820C 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.

Mode LPT1:,,P

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 technical support to verify that

the LPT.vxd file in Windows 95 is the latest version.

7. If possible, try installing the printer driver software on

another computer and try printing.

NOTE: If printing problems continue, contact the Hewlett-Packard

Customer Support Center at 1-208-323-2551, Monday through Friday,

6 am to 10 pm, Saturday, 9 am to 4 pm Mountain Standard Time.
