Help installing missing dependencies for HPLIP

Hi there!

While trying to set up my printer and installing HPLIP, I got this message:

MISSING DEPENDENCIES
--------------------
Following dependencies are not installed. HPLIP will not work if all REQUIRED dependencies are not installed and some of the HPLIP features will not work if OPTIONAL dependencies are not installed.
Package-Name Component Required/Optional
libcrypto network REQUIRED
libnetsnmp-devel network REQUIRED
sane-devel scan REQUIRED
pil scan OPTIONAL
pyqt4-dbus gui_qt4 REQUIRED
python-devel base REQUIRED
cups-devel base REQUIRED
python-dbus fax REQUIRED
reportlab fax OPTIONAL
pyqt4 gui_qt4 REQUIRED
libusb base REQUIRED
libtool base REQUIRED
cups-image base REQUIRED
python-notify gui_qt4 OPTIONAL
xsane scan OPTIONAL
libjpeg base REQUIRED
dbus fax REQUIRED
Do you want to install these missing dependencies (y=yes*, n=no, q=quit) ?

and then

INSTALL MISSING REQUIRED DEPENDENCIES
-------------------------------------
note: Installation of dependencies requires an active internet connection.
warning: Missing REQUIRED dependency: python-devel (Python devel - Python development files)
warning: This installer cannot install 'python-devel' for your distro/OS and/or version.
error: Installation cannot continue without this dependency. Please manually install this dependency and re-run this installer.

Now, I've since managed to install a few of these on my own. The ones I haven't been able to figure out how to install are:

sane-devel
pil
pyqt4-dbus
cups-devel
reportlab
pyqt4
libusb
libtool
cups-image
libjpeg
dbus

Out of these, I get the following for libtool and dbus

and this message for the rest of them

E: Unable to locate package [package name]

I'd really appreciate any input as to how to install the these/ get my printer running!

printer is HP DeskJet 3762
elementary OS 0.4.1 Loki for a distro

Thanks in advance!
