The fiducial nozzle deposits a marks on a medium. The printing device forms an image on the medium. ## Claims ### Claim 1 A floor printer comprising: a means for printing an image on a medium; a means for determining a position of the floor printer; and a nozzle on a bottom of the floor printer, wherein the nozzle deposits a layer over the printed image; and wherein the means for determining the position of the floor printer includes a magnetic sensor for detecting magnetic gridlines on the medium. ### Claim 2 A floor printer comprising: a means for printing an image on a medium; a means for determining a position of the floor printer; and a nozzle on a bottom of the floor printer, wherein the nozzle deposits a layer over the printed image; and wherein the means for determining the position of the floor printer includes a fiducial nozzle on the bottom of the floor printer, and also includes a sensor having a filtered light that shines on a marking made by the fiducial nozzle, the filtered light corresponding to a color of the marking, wherein the means for determining the position of the floor printer further includes a means for producing, receiving and reading reflectance data based upon the light shone on the marking. ### Claim 3 A floor printer comprising: a means for printing an image on a medium; a means for determining a position of the floor printer; and a nozzle on a bottom of the floor printer, wherein the nozzle deposits a layer over the printed image; and wherein the means for determining the position of the floor printer includes a ground tracking radar system. ### Claim 4 (depends on 2) The floor printer of claim 2 wherein the marking includes a line substantially paralleling a print swath of the floor printer. ### Claim 5 (depends on 2) The floor printer of claim 2 wherein there are three fiducial nozzles in a first corner, and another three fiducial nozzles in a second corner, wherein the three fiducial nozzles are substantially aligned with a directional movement of the printer. ### Claim 6 (depends on 5) The floor printer of claim 5 wherein each of the three fiducial nozzles includes two edges fiducial nozzles, and a middle fiducial nozzle that deposits a different fluid than the edge fiducial nozzles. ### Claim 7 (depends on 6) The floor printer of claim 6 wherein the edge fiducial nozzle nearest a front edge of the printer deposits a first fluid, and the middle fiducial nozzle deposits a second fluid over the first fluid. ### Claim 8 (depends on 7) The floor printer of claim 7 wherein the first fluid has a greater reflectance rate than the second fluid, the floor printer further comprising a locating device that is responsive to reflectance of fluids on the medium. ### Claim 9 (depends on 2) The floor printer of claim 2 further comprising a translational mechanism that enables the floor printer to automatically move to print on an adjacent print swath. ### Claim 10 (depends on 2) The floor printer of claim 2 wherein the means for printing includes a carriage containing print cartridges that moves along a slide rod in a direction perpendicular to a translational direction of the printer. ### Claim 11 (depends on 2) The floor printer of claim 2 further comprising a heater on the bottom of the floor printer to dry the image deposited by the printing device. ### Claim 12 (depends on 2) The floor printer of claim 2 further comprising a heater to dry the deposited layer. ### Claim 13 (depends on 1) The floor printer of claim 1 wherein the means for printing includes a printhead along the bottom of the floor printer. ### Claim 14 (depends on 1) The floor printer of claim 1 wherein the means for printing includes a carriage holding print cartridges along the bottom of the floor printer. ### Claim 15 (depends on 1) The floor printer of claim 1 further comprising a heater on the bottom of the floor printer to dry the image deposited by the printing device. ### Claim 16 (depends on 1) The floor printer of claim 1 further comprising a heater to dry the deposited layer. ### Claim 17 (depends on 1) The floor printer of claim 1 wherein the means for printing includes a carriage containing print cartridges that moves along a slide rod in a direction perpendicular to a translational direction of the printer. ### Claim 18 (depends on 1) The floor printer of claim 1 further comprising a translational mechanism that enables the floor printer to automatically move to print on an adjacent print swath. ### Claim 19 (depends on 3) The floor printer of claim 3 further comprising a heater on the bottom of the floor printer to dry the image deposited by the printing device. ### Claim 20 (depends on 3) The floor printer of claim 3 further comprising a heater to dry the deposited layer. ### Claim 21 (depends on 3) The floor printer of claim 3 wherein the means for printing includes a printhead along the bottom of the floor printer. ### Claim 22 (depends on 3) The floor printer of claim 3 wherein the means for printing includes a carriage holding print cartridges along the bottom of the floor printer. ### Claim 23 (depends on 3) The floor printer of claim 3 wherein the means for printing includes a carriage containing print cartridges that moves along a slide rod in a direction perpendicular to a translational direction of the printer. ### Claim 24 (depends on 3) The floor printer of claim 3 further comprising a translational mechanism that enables the floor printer to automatically move to print on an adjacent print swath.
