The method of claim 1, further comprising: electronically by a computer or processor, determining if the portion of the data corresponding to a region of print media where none of the information is to be printed meets one or more predetermined criteria; andelectronically by a computer or processor, designating the first data portion for printing by the first print head and the second data portion for printing by the second print head when the one or more predetermined criteria are met. 10. The method of claim 9, wherein at least one of the one or more predetermined criteria require the region of print media where none of the information is to be printed to comprise a predetermined physical size. 11. The method of claim 10, wherein the predetermined physical size corresponds to a predetermined length of print media along a media feed path. 12. The method of claim 11, wherein the predetermined length ranges from approximately 0.5 to 2.0 mm. 13. The method of claim 11, wherein the predetermined length ranges from approximately 1.0 to 1.25 mm. 14. The method of claim 10, wherein the data represents a bitmap comprising one or more dot rows, and the predetermined physical size corresponds to a predetermined number of dot rows of the bitmap. 15. The method of claim 14, wherein the predetermined number of dot rows range from approximately 4 to 16. 16. The method of claim 14, wherein the predetermined number of dot rows range from approximately 8 to 10. 17. The method of claim 1, further comprising: electronically by a computer or processor, determining if a portion of print media required to print the first data portion and a portion of print media required to print the second data portion meet one or more predetermined criteria; andelectronically by a computer or processor, designating the first data portion for printing by the first print head and the second data portion for printing by the second print head when the one or more predetermined criteria are met. 18. The method of claim 17, wherein at least one of the one or more predetermined criteria require the portion of print media required to print the first data portion and the portion of print media required to print the second data portion to differ in size by a predetermined amount. 19. The method of claim 18, wherein the predetermined amount corresponds to a predetermined length of print media along a media feed path. 20. The method of claim 18, wherein the data represents a bitmap comprising one or more dot rows, and the predetermined amount corresponds to a predetermined number of dot rows of the bitmap. 21. The method of claim 18, wherein the predetermined amount corresponds to a portion of print media required to print predefined print data. 22. The method of claim 21, wherein the predefined print data comprises one or more of a coupon, a logo, a serialized cartoon, a condition of sale, a graphic, an advertisement, a security feature, rebate information, contest information, ticket information, and legal information. 23. A method of splitting data for printing by a first and a second print head of a two-sided printer, the method comprising: electronically by a computer or processor, identifying a portion of the data transverse to a print direction comprising no information for printing;electronically by a computer or processor, designating a first portion of the data for printing by the first print head before the portion of the data transverse to the print direction comprising no information for printing is identified; andelectronically by a computer or processor, designating a portion of the data for printing by the second print head after the portion of the data transverse to the print direction comprising no information for printing has been identified. 24.
