usb printer testing(modified)

[R1nso13@aol.com]

I understand that a command such as 'lptest 20 10 > /dev/lp1' (or lp0) will 
print a test page to a parallel port printer assuming the device file 
properly links to the printer. I have a usb printer instead (as well as a 
kernel that supports it, and the device file '/dev/usb/lp0' with the, i 
think, correct major and minor numbers 180, and 0). I know I need to install 
drivers for the printer, but are the drivers nessicary for a simple test like 
'lptest 20 10 > /dev/usb/lp0'? I don't get any error messages from this 
command, but the printer doesn't do anything.

I know there are programs such as printtool that will automatically configure 
the printservices, but I would prefer to do without them. So a simple "yes, 
you need this driver to execute that command" (which i think is unlikely 
because according to linux-usb.org the driver is in the kernel) or "no, 
here's the problem:" would be good for now (in addition to some explanation 
of why a seperate usbdevfs was created).

all I've done so far: 1. set up kernel w/ usb printer support 2. made 
/dev/usb/lp0 3. Tried to issue 'lptest 20 10 > /dev/usb/lp0"

thanks

by the way, its a lexmark Z32 connected to the usb port
