This is free software, and you are welcome to distribute it

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball
has the proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode
will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

Bought this printer the other day so before i got it I Installed hplip and hplip-gui so it was ready for printer to be plugged in..

Shutdown the computer. Setup the printer with ink and then plugged in via USB.

Turned Computer on -

Linux mint and the hplip-gui did not find anything by its self - .. I went through the setup wtih hplip-gui and it could not find any devices

so i went into System/Printers and that was able to configure the printer.. I can now print all good. However when i open Simple-Scan in the Mint menu it cannot find a Scanner, and when i go to preferences - then -"Scan Source" it is greyed out and there is no options.

The scanning function it self works.. i can copy a page on it directly on the printer

Any idea what i can do to get scanning to work? thanks
