ABSTRACT:
A printer architecture structure in which a flexible external case is used to compress and sandwich internal printer structure comprised of a rigid metal base and printer chassis structure by nominally compressing resilient pads between the chassis structure and case top and side walls. Additional resilient pads between the base and chassis structure are ordinarily nominally uncompressed by the flexible case except during application of shock loads during shipment or vibrations during printer operation. The construction minimizes transmission of externally applied shock loads through the internal components of the system and assists in containing vibrations and noise generated during printer operation interiorly of the case. The relatively rigid base comprises a metal enclosure for RF shielding of the electronic components.
