Adding and/or configuring CUPS printers can be done with lpadmin(8), but
for a quick and easy (graphical) setup, after starting the CUPS daemon,
point your browser to:
http://localhost:631
If you want to print to non-Postscript printers or use CUPS bundled PPD
files (i.e. drivers), you'll need to install gstoraster. You will also
most probably want to install foomatic-filters which provides a
universal filter script along with the foomatic-db-engine package which
will allow you to generate a PPD (Printer Postscript Description) file
for your printer.
Depending on your printer model you may also need to install some driver
package like (non-exhaustive list): hplip/hpijs, gutenprint, foo2zjs,
splix...
To be able to use CUPS printers from GTK applications, the corresponding
package needs to be installed: gtk+2-cups and/or gtk+3-cups.
USB
===
Since USB printing will be handled by libusb, you need to allow the
_cups user access to the corresponding USB endpoint. To do so, find
where your printer is attached to using `sudo usbdevs -vd` then change
the ownerships accordingly.
e.g.
Controller /dev/usb5:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), ATI(0x1002), rev 1.00
uhub5
port 1 addr 2: full speed, self powered, config 1, USB MFP(0x082f), EPSON(0x04b8), rev 1.00, iSerialNumber L83010704250947490
ugen0
$ sudo chown _cups /dev/ugen0.* /dev/usb3
The reason we are changing the user and not the group is that it will
allow for multi-function devices to work for both printing and scanning
(e.g. by being owned by _cups:_saned).
To preserve your changes after a system update, use rc.local(8).
e.g. for a multi-function printer/scanner add the following lines:
chown _cups:_saned /dev/ugen0.* /dev/usb1
*** WARNING ***
ulpt(4) needs to be disable in the kernel (see config(8)) or the printer
will not be available to libusb.
