hplip-firmware 2.7.7-0ubuntu4 (sparc binary) in ubuntu gutsy

 The HP LaserJet 1000, 1005, 1018, and 1020 need their firmware to
 be uploaded into them whenever they are turned on. HP ships the firmware
 for the two newer models, LaserJet 1018 and 1020 with the HPLIP
 package.
 .
 To install only the two firmware files install this package.
 .
 Note that HPLIP does not ship a printer driver for the HP LaserJet 1018
 and 1020. You need to install the foo2zjs package to get a driver.
 foo2zjs will also take care of loading these firmware files into the
 printer.
