Got the USB print server working (with both a Brother HL-2140 & a Samsung ML-1740 lasers).

Without reading the book, yesterday I tried (unsuccessfully) to set the printers up as "network printers". In reality they are not "network printers" but rather "local" printers accessible across the network (via IP).

(Think of the NAS as a "computer" with an attached local printer.)

Today, without reading the book, I tried unsuccessfully to set the printers up as a "local printer", but connected to an IP port. (I read about that yesterday & thought, ah, the answer.)

Today after reading the book, it presented me with a question. When using my file manager, I could not open the NAS directly (to its root) but only to a shared subdirectory of root.

So with my file manager I could see & connect to something like:

\\NAS\Music
\\NAS\Office
\\NAS\Porn

Though I could not connect directly to \\NAS & traverse my way to Music, Office, Porn.

The book showed examples with Explorer opening \\NAS (itself) & then directories for Music, Office, & Porn. It also showed a printer icon, LP (line printer, in UNIX speak).

It was this "LP" that I was not seeing from within my file manager, making it difficult to follow the books directions on setting up the printer. Hence my other methods of attempting to set up the printer.

Experimenting, I see that using Windows Explorer, I can (type in &) connect directly to \\NAS (rather then directly to \\NAS\Music). And when connected to \\NAS, then in addition to Music, Office, Porn, I then also see LP.

Now with access to LP, I can then follow the book to set up the printer. (Right+click LP, Connect... which brings up the Add Printer Wizard, select printer & go. You have to do that from each computer on the network that you want to have access to the "network" (aka "shared" printer.)

Now seeing that in Explorer I can access (the address) \\NAS itself, I figure I must be able to do the same in my file manager & in fact I can. Just had to figure it out.
