Media processing device with enhanced media and ribbon loading and unloading features

A printhead pressure adjustment assembly comprising:

• a barrel defining an internally threaded bore;
• a threaded insert disposed within the barrel, wherein the threaded insert defines an external thread configured to engage the internally threaded bore of the barrel;
• a biasing element configured to apply a biasing force to a printhead;
• and
• a spring coupled to the threaded insert, wherein the spring is compressed, increasing the biasing force, in response to the barrel being rotated in a first direction, and wherein the spring is decompressed, decreasing the biasing force, in response to the barrel being rotated in a second direction, opposite the first direction.

A printer comprising:

• a printhead assembly;
• a printhead pressure adjustment assembly configured to apply pressure to the printhead assembly, the printhead pressure adjustment assembly comprising:
• an internally threaded barrel configured to rotate about an axis, wherein the barrel comprises biasing pressure level demarcations arranged around a perimeter of the barrel;
• a threaded insert comprising external threads, wherein the external threads of the threaded insert engage the internal threads of the barrel;
• a biasing element received within the barrel and configured to apply a biasing force generally along the axis to the printhead assembly, wherein the biasing force applied to the printhead is adjustable in response to the barrel being rotated;
• and
• a spring arranged to apply the biasing force to the biasing element, wherein the spring is compressed and the biasing force is increased in response to the barrel being rotated in a first direction, and wherein the spring is decompressed and the biasing force is decreased in response to the barrel being rotated in a second direction, opposite the first direction.
