From: Talib Al-Ali Talib on 21 May 2007 02:10 Hello everyone, I've been using the following command to programmatically add & install LPT printers connected directly to WinXP computers. Everything goes ok with that. However, when I try the same command to connect a USB printer, it fails. Here is what I did. rundll32 printui.dll,PrintUIEntry .... /r "LPT1:" ... (The dots represents other paramteres that are non-relevant to my question) Above command works OK !! with LPT printers. Then, I assumed I would have to make below changes to make it work for USB printers rundll32 printui.dll,PrintUIEntry .... /r "USB001" ... Still, the command gets processed successfully and the printer is added. BUT !! I cannot print a test page, I get an error message that printing is failed and the test page is visible at the printer queue. It will only work if I manually change the port of that printer to another USB (2, 3, ...) from the list of ports on printer properties. I don't know how to assign the right port to a new printer using the command line. I found no documentations on adding USB printers using the above command (which is supposed to support USB ports). I'd really really appreciate it if someone can help me out with this issue - I've been invistigating on it for so long time. Talib

Also make sure that the USB device is actually plugged into the USB port. -- Stefan Kuhr "Lesen schadet der Dummheit"
From: Talib Al-Ali on 21 May 2007 09:19 Thanks Stefan, I downloaded the tool and tried to use it but I had no clue on the HWID, do you know where I can get it for a particular USB printer/device? is it unique for each device or is it related to the USB port into which the device is connected? Thanks again for your response..
