Prints come out stretched - HP Officejet Pro 8620 - CentOS/RHEL 7

[Jack Beckitt-Marshall]

I have a problem with my HP Officejet Pro 8620 within CentOS 7. Essentially, when I try to print from certain programs (such as Firefox), prints come out stretched, and do not appear on the page as they are supposed to. The attached JPEG shows my problem. This problem does not exist under Windows, so it is not a problem with the printer itself, but it seems a little strange.

This is free software, and you are welcome to distribute it
under certain conditions. See COPYING file for more details.

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]
