Problems with DOS Program in Windows 7 32-bit

We bought our first couple of Windows 7 computers at work and had 32-bit installed so we can install our DOS program.  However, we're having a couple of issues.  The latest was the employee was receiving memory errors when he tried to print.  I saw the memory tab, but unsure about the settings.  How would you all solve this problem and are there any other common problems in moving from XP to Windows 7 32-bit that affect a DOS program that I should know?

Thanks.

Regarding the former, our boss doesn't want us running in compatability mode as we have low-level users and does not want them to to get confused.  Regarding third-party printing, we print fine to our printers using the netuse command and setting LPT1, 2, or 3.
Compatibility mode is set by right clicking on the exe file and select xp option...you dont have to install xp for that.

I think perfectpc: has provided a good resolution.

Compatability mode is grayed out because it is on a network drive.
Can also try program like virutal dos.

I am sorry its dosbox

Following are a couple of responses from a previous post.  Isn't the 32-bit of Win7 similar to any virtual DOS environment?  We'd prefer to stay in Win7 32-bit if possible.

Tried DOSbox and it didn't work.

Turns out that Sweeps was correct:  our Win7 did come with XP mode.  Turns out that the reason it didn't work was because we use our DOS program from a drive on the server.  Didn't know that you had to join the virtual XP environment to the domain as it is just as if it is a different computer.  It took a bit to join the domain (my partner had to enable something in the virtual settings), but once we did everything worked fine.  Giving credit because I didn't give enough information -- that we access our DOS program from a mapped drive on the server.  And, giving credit to the first person to mention XP VM.
Does changing any of these settings help memory issues?

Can u post the error message or screenshot.

Will try, but just checked and it worked for him today.  It is probably just a problem in one module of his DOS app.
There is no error mesage; it just froze.  Changed to a different printer and this seems to solve the problem.  However, giving credit because I think we are being stubborn and just need to run in compatability mode.
