How we change font in dos foxpro

Many DOS programs were designed to write directly to the printer's buffer, rather than to a spooler like more modern applications. It sounds like FoxPro is doing exactly that - and isn't designed to release the job until being completely closed.

install dos printer drivers.

change the connecting cable serial or parallel what you have it may help you.

You are on the right track, but you need to change the font (typeface) that is being used to one that has a fixed character width.

THE CUSTOMER SHOULD TRY REINSTALLING THE DRIVERS,AND IF PROBLEM PESISTS HE SHOULD TAKE THE PRODUCT TO AN HP SUPPORT END. 

You write "type the above line at command prompt". I dont't know Where exactly to write? Can you tell me!

You can access your printer connected to USB port with loop back configuration and print from DOS.
Not only that, you can also print to a printer on the network

Try
Net use lpt1: \\Comp name\ printer name /persisten:yes

you can do this thru printer maping
try this DOS command
net use LPT1 \\computer name\printer

To answer the question, I need to k**w if your DOS session is running inside Windows. As this is the most likely scenario, I'll answer assuming that - the answer will be different for DOS only systems.

Has the faulty LPT1 port has actually been removed? If it has, why **t just alter the port number of LPT3 back to LPT1 ? This can be done with jumpers on an old style card, or from device manager inside Windows if plug and play. If **t, you can try the following:

1: If the printer is already installed in Windows on LPT3, skip to step 3:
2: Install the printer in Windows. If you don't have a suitable driver for it, you can use Generic/Text only driver.
3: Right click on the printer, go to sharing, and make the printer shareable. Use a share name of 11 or less characters and ** spaces - e.g. EPSONLX500
4: From the CMD prompt, type the command:

net use lpt1: \\%computername%\Sharename

e.g.

net use lpt1: \\%computername%\EPSONLX500

**te that you do **t need to replace %computername% with your exact computer name - the machine will do it for you.

Finally, for others reading this, you can also use this technique to print from DOS to most "intelligent" USB printers (Hi end Laser, Dot Matrix etc). It probably won't work with "dumb" GDI printers or All-in-ones where Windows has to do all the work. If the printer supports PCL or ESCP printing languages, you are probably going to be OK.

yes intel 945 chipset is not proper work on Dos based programs.u can use foxpro for window
