It's hard to tell what you're saying. Yes, even Windows includes an FTP client, and yes, it can be used to transfer files to a JetDirect. Kind of sounds like you're saying that since most people don't use it, it doesn't exist, but that can't be right. > And Print Server is a SERVER not printer driver so it may allow to have > access to printer, but the printer just won't print without Printer Driver.

For example, create a text file using a >> simple text editor (Notepad, not Word), then send it to the printer via >> FTP or port 9100 or lpd or several other ways. No driver. In more detail, and even on Windows: Run Notepad. Type in a few lines of text: "Printers can print files in their native PDLs without drivers. This page is proof of that." Save the file as sample.txt. This is a plain ASCII file. Close Notepad. Start a command shell (cmd). FTP the file to the printer. For this example, we have a JetDirect print server at 192.168.1.50: ftp 192.168.1.50 Connected to laser. 230 FTP Server Ready User (laser:(none)): Press Enter for no user name. 331 Enter password.

No driver was used to create the file or to print it. -- Warren Block * Rapid City, South Dakota * USA

One might define a driver as that which does both things. So if you do both manually, you can print without a driver. If you do only one thing, then a driver is that which does the other. Fred

AFAIR the old dot matrix printers didn't need drivers, you just sent ASCII characters to them, just like you used to do with the ASR33 Teletypes, and Dec Writer page printers. The drivers came in when you had to convert an application produced document to something the printer could understand. And if you got it wrong, instead of a nice printed page you got sheet after sheet of Postscript command language, and had to pull the plug before you ran out of paper.

You seem very confused about all this, and I'm sorry if I haven't been clear enough. In fairness, Windows makes a lot of things more difficult than they need to be, and it is confusing. Let me try to clear up a few things: A "printer driver" is a program that converts application output into a format the printer can understand. If a file is created that the printer can understand directly, no driver is needed. Any of a number of methods can be used to deliver a file to the printer. Usually this is by parallel, USB, or Ethernet. A shorter example that is hopefully easier to understand: An HP LaserJet 4250 printer is attached to a Windows XP computer with a standard parallel cable. A command shell (cmd) is started and the edit command is used to create a text file called sample.txt: C:\>edit sample.txt The file has these contents: This was created and printed without a driver at all! ^L The last line is a formfeed character, entered with Ctrl-P Ctrl-L. The copy command is used to send the file directly to the printer via the parallel port: C:\>copy /b sample.ps lpt1: The page prints. No driver was used or needed. Note that this same procedure works in MS-DOS, which doesn't even have printer drivers. It will also work with most printers. -- Warren Block * Rapid City, South Dakota * USA
