The method of claim 9 and wherein the double sided tape is located relative to the leader portion at a location from the leading end of the leader portion so that when the supply core and take-up core are mounted on the cassette assembly with the thermal ribbon wound about the cassette assembly and the cassette assembly is supported in the printer apparatus the double sided tape is positioned downstream of a print nip where the printer would engage the thermal ribbon so that the double sided tape does not engage receiver media during printing. 11. The method of claim 7 and wherein the thermal ribbon includes a leader portion that extends from an outer convolution of the roll of thermal ribbon with a leading end portion of the leader portion being attached to the take-up ribbon core and a double sided tape being attached to the leader portion so as to adhesively couple the leader portion to the outer convolution of the roll and wherein the adhesive coupling is sufficiently strong so as to prevent unraveling of the thermal ribbon from the roll on the supply core when the take-up core is supported by an operator and the supply core with the roll of ribbon thereon is allowed to dangle freely. 12. The method of claim 11 and wherein the double sided tape is located relative to the leader portion at a location from a leading end of the leader portion so that when the supply core and take-up core are mounted on the cassette assembly with the thermal ribbon wound about the cassette assembly and the cassette assembly is supported in the printer apparatus the double sided tape is positioned downstream of a print nip where the printer would engage the thermal ribbon so that the double sided tape does not engage receiver media during printing. 13. The method of claim 6 and wherein the thermal ribbon includes a leader portion,formed of the thermal ribbon, that extends from an outer convolution of the roll of thermal ribbon with a leading end portion of the leader portion being attached to the take-up ribbon core and a double sided tape being attached to the leader portion so as to adhesively couple the leader portion to the outer convolution of the roll and wherein the adhesive coupling is sufficiently strong so as to prevent unraveling of the thermal ribbon from the roll on the supply core when the take-up core is supported by an operator and the supply core, with the complete roll of ribbon thereon except for the leader portion, is allowed to dangle freely. 14. The method of claim 13 and wherein the double sided tape is located relative to the leader portion at a location from a leading end of the leader portion so that when the supply core and take-up core are mounted on the cassette assembly with the thermal ribbon wound about the cassette assembly and the cassette assembly is supported in the printer apparatus the double sided tape is positio ned downstream of a print nip where the printer would engage the thermal ribbon so that the double sided tape does not engage receiver media during printing. 15. For use in the method of claim 6 a thermal ribbon supply and take-up for loading into a cassette assembly of a thermal printer apparatus, the ribbon supply and take-up comprising: a supply core having a supply of thermal ribbon wound thereon as a roll and a take-up core,wherein the thermal ribbon includes a leader portion,formed of the thermal ribbon, that extends from an outer convolution of the roll of thermal ribbon with a leading end portion of the leader portion being attached to the take-up ribbon core and a double sided tape being attached to the leader portion so as to adhesively couple the leader portion to the outer convolution of the roll and wherein the adhesive coupling is sufficiently strong so as to prevent unraveling of the thermal ribbon from the roll on the supply core when the take-up core is supported by an operator and the supply core, with the complete roll of ribbon thereon except for the leader portion, is allowed to dangle freely. 16. The ribbon supply and take-up of claim 15 and further comprising: wherein the double sided tape is located relative to the leader portion at a location from a leading end of the leader portion so that when the supply core and take-up core are mounted on the cassette assembly with the thermal ribbon wound about the cassette assembly and the cassette assembly is supported in the printer apparatus the double sided tape is positioned downstream of a print nip where the printer would engage the thermal ribbon so that the double sided tape does not engage receiver media during printing. d the lower shell cylinder are rotated relatively in a direction of the cam portion. associated by face-to-face contact relationship with the platen so as to restrict substantially only said airflow through said belt by a combined construct comprising the platen and the belt by providing a predetermined net porosity of said platen and said perforated belt in combination such that said airflow is a substantially uniform airflow established for holding an ink-jet print media on said belt; and fluidically coupling the vacuum ports to channels oriented across the platen substantially perpendicularly to the predetermined direction. 7.
