PRINT--Notes

Length of a PRINT queue entry

Each print queue entry can contain a maximum of 64 characters. Each queue   
entry includes the drive letter, directory, and any subdirectories.

Limitations on switches

You can only use the /D, /B, /U, /M, /S, and /Q switches the first time you
use the PRINT command after starting MS-DOS. To use one of these switches
after using PRINT, you need to restart MS-DOS.

Use an application's print command when possible

Many applications have their own print commands. You should use an
application's print command to print files that you create with the
application.
