JSI Tip 1410. How can I automate DOS default network printer assignment in a logon script?

To use a network printer in a DOS program, you must issue a:

NET USE LPTx: \ComputerNamePrinterShare.

In tip 0672, we learned that the default printer information is located at:

HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindowsDevice

Using REGFree, we can add either of the following to a logon script:

for /f "Tokens=1-5 Delims=,: " %%i in ('reg -listvalue "HKCUSoftwareMicrosoftWindows NTCurrentVersionWindowsDevice"') do set prt=%%j&set port=%%lnet use %port%: %prt%

               OR

for /f "Tokens=2 Delims=, " %%i in ('reg -listvalue "HKCUSoftwareMicrosoftWindows NTCurrentVersionWindowsDevice"') do set prt=%%inet use LPT1: %prt%
