Detailed Description of the Preferred Embodiment With reference to FIGURE 1, there is shown an assembly generally indicated at 10 of a portable printer generally indicated at 11 and a portable data entry device generally indicated at 12. The printer 11 and the device 12, individually, as well as the assembly 10 are portable and in particular are hand-held for ease of use. The device 12 includes a scanner 13 at its front end for scanning a bar-coded label L. The device 12 also has manually operable keys 14 and a display 15. The scanner 13, the keys 14 and the display 15 are housed in an elongate relatively thin housing 16. Manually depressing buttons 14' operates the scanner 13. The printer 11 is shown to have an elongate housing 17 having opposed mirror-image housing sections 18 and 19. The front portion of the housing 17 has a compartment or space or pocket 20 for receiving and releasably holding the data entry device 12. The compartment 20 has an open top 21 to enable the keys to be operated and to enable the display 15 to be seen. The compartment 20 is channel-shaped as diagrammatically depicted in FIGURE 6 to capture the data entry device 12. As shown, the housing 17 has flanges 22 and 23 which help retain the device 12 captive in the compartment 20. The front end of the compartment 20 is open as indicated at 24 to enable the device 12 to be slid into the compartment 20. The device 12 is releasably latched in the compartment 20 by opposed latches 25. The latches 25 are each comprised of a pad 26 flexibly secured to a wall 27. The pads 26 have opposed projections 28 which are received in recesses 29 in the housing 16 of the device 12. By simultaneously depressing both pads 26 rearwardly of the wall 27, the projections 28 are withdrawn from the recesses 29 which allows the device 12 to be slid out of the compartment 20. The underside of the device 12 has a 10-pin connector 30 which cooperates with a mating 10-pin connector 31 on the housing 17. As the device 12 is slid into the compartment 20 in the direction of arrow A in FIGURE 2, the connector 30 at the rear end of the device 12 connects with the connector 31 at the rear end of the compartment 20, thereby enabling the data entry device 12 to control the printer 11. The latches 25 are latched when the connectors 30 and 31 are connected. As is apparent from FIGURE 3, the underside of the printer housing 17 has a hollow or concave surface 32 for receiving the palm of the user's hand. A strap 33 can fit about the back of the user's hand. The strap 33 can be a continuous loop of a hand as shown in FIGURE 3. FIGURE 3 also shows the device 12 diagrammatically and that a label roll R and a prior art print module or print mechanism generally indicated at 34 are disposed at a rear portion of the printer 11. The label roll R is illustrated as being comprised of a label web (or a web of labels) W received in space 35 in the housing 17. The roll R is suitably supported either at its central opening 36 or simply in a cradle 37 as shown. The web W passes from the roll R between a battery powered thermal print head 38 and platen in the form of a platen roll 39. The printed label web W exits the housing 17 at a slot 40 one side of which is formed by a tear edge 41. FIGURE 7 shows that the print module 34 comprises a frame 42 which has sockets 43 and 44. The module 34 includes a platen roll 39 having a shaft 46. The shaft 46 is releasably held in the sockets 43 and 44 in the FIGURE 3 position. The module 34 further includes an electric motor 47 and gearing generally indicated at 48. The gearing 48 includes gear 49 on the shaft 46. Springs 50 which bear against a support 51 resiliently mount the print head 38. The platen roll 39 is rotatably mounted to a cover 52. In particular, the shaft 46 passes through a flange 53 and is removably received in a C-shaped cutout 54 in a flange 55. The end of the cover 52 opposite the platen 45 has a pair of outwardly extending projections 56 for receipt in opposed recesses 57 in the housing sections 18 and 19. Accordingly, the cover 52 is pivotally mounted for movement between a closed or operating position shown in FIGURES 1 and 3 and an open or non-operating position providing an access opening as illustrated in FIGURE 2. It is apparent when the cover 52 is in the position shown in FIGURE 2, a label roll R can be readily inserted into the space 35. If the roll R has a core C as shown the core can be readily removed. Also, the print head 38 and the platen roll 39 can be readily cleaned when the cover is in the open position. If required, the platen roll 39, its shaft 46 and its gear 49 can be readily replaced by snapping the portion of the shaft 46 between the flanges 55 and the gear 49 out of the socket 44, and pulling the other end of the shaft 46 out of the hole in the flange 53.
