I am trying to setup a usb printer on the computer of a friend
the printer is present, but on the cups webinterface it does not show up

this drives me really crazy..
Imy friend has a router with usb port and printer support - so I put the printer there, to get it away from the usb port.
I have a crunchbang CD with me and tested it there - the printer works without any problems - I did exactly the same adjustments and it the jobs are cancelled - see attachment
Edit: the second screenshot is from crunchbang to compare

ok - I think I have the solution: we miss the package cups-filters
From CUPS 1.6.0 on, this package is required for using printer drivers with CUPS under Linux. With CUPS 1.5.x and earlier this package can be used optionally to switch over to PDF-based printing.
see: http://www.linuxfoundation.org/collaborate/workgroups/openprinting/cups-filters
http://www.openprinting.org/download/cups-filters/
it would be nice, if sombody can compile it

I see the same thing happening when trying to install my old HP Laserjet P1006 with hplip-3.12.2 (self-compiled). Running hp-setup gives the error "unable to setup printer queue." Printer seems to be detected on the USB port, but CUPS cannot find the printer. The printer is wired, not wireless, print-function only, monochrome.
Other distros I've used also have such packages as foomatic-engine, foomatic-rip, hplip-gui, which are lacking in the Slitaz 4.0 repository, so I think more priority should be given to printing support in upcoming Slitaz releases.
I'm looking at compiling cups-filters, compatible with cups version 1.4.6.

I have converted cups-filters and cups-filters-ghostscript from opensuse
https://www.dropbox.com/s/gjmr7c6rf421x3j/cups-filters-1.0.58-2.1.3.tazpkg?dl=0
https://www.dropbox.com/s/5o3gkyyei4qp2ba/cups-filters-ghostscript-1.0.58-3.2.tazpkg?dl=0
now the printer is present, but when I try printing, but I get the error > Idle - "Can't detect file type" <

In most cases cups is a part of the repository, so people will install it from there.
But that method can make it impossible for cups to detect the usb-printer. Why ?
After all, I found, cups must be a special version (1.5.3 or higher) and it must be compiled
with libusb-developer-files. You can test that with
ldd /usr/lib/cups/backend/usb
and should get a line like
libusb-1.0.so.0 => /lib/x86_64-linux-gnu/libusb-1.0.so.0 (0x00007fab56173000).
When you type
/usr/lib/cups/backend/usb,
you should get a full description of the usb-printer like
direct usb://HP/DESKJET%20600 "HP DESKJET 600" "HP DESKJET 600" ...
After that with
lpinfo -v
you should see the usb-printer with a line like
direct usb://HP/DESKJET%20600.
If that does not work, you can type
chmod 700 /usr/lib/cups/backend/usb
and
chmod 666 /dev/bus/usb/x/y
with x is the Bus-number and y is the Device-number of the printer, which you get
from the corresponding line of
lsusb.

There is also the option to configure a parallel-printer by setting a symlink, see:
https://unix.stackexchange.com/questions/245154/dell-3110cn-usb-printer-not-detected
But when you have an usb-printer, cups should be able to find it.

Some additional lines about detecting usb-printer with cups.
The first thing is to have support from the kernel. Also old kernels offer it (even slitaz 3.0
with kernel 2.6.30.6). But you will not see the full name of the printer (HP_DESKJET_600), only
a line like:
usb://Unknown/Printer
This means, that you can install the printer correctly, when you know the right ppd-file. When you
want to install it from the web-interface automatically, the wrong ppd-file could be chosen.
The service to see the full name of the printer comes from the file /drivers/usb/core/devio.c of
the kernel-sources and is seen first in the kernel 3.0.10.
The detection of the usb-printer within CUPS happens in the file /backend/usb-libusb.c of the
cups-sources. If you want to compile a CUPS-version 1.5.2 or older, which detects the usb-printer,
you can copy a usb-libusb.c of CUPS 1.5.3 with some modifications an compile it with
LIBS="-lusb-1.0" ./configure --prefix=/...
