A manual printing system (MPS) for topographical marking of at least one marking topographical information on a surface of a construction provided with at least one topographic mark, said manual printing system being adapted for being handled and moved by an operator, said manual printing system (MPS) comprising:
- a mobile printing carrier (MPC) with an ink printing head (1);
- a frame (F) adapted to be pushed against the surface (S) of the construction to be provided with at least at least one topographical marking information, said frame (F) being provided (a) with a marking window (MW) through which the printing of said at least one topographical marking information by the ink printing head (1) is possible on the surface (S) of the construction, as well as (b) with guiding means (6) adapted for guiding along a movement axis, a linear movement (arrow LM) of the mobile printing carrier (MPC), with respect to the marking window (MW) of the frame (F), whereby the said marking window (MW) defines a marking zone to be provided with said at least one topographical marking information on the surface (S) of the construction to be provided with said at least one topographical marking information;
- at least one topographic positioning means (5), said at least one topographic positioning means (5) being adapted for at least a visual control by the operator, of the position of the frame (F) or mobile printing carrier (MPC) with respect to said at least one topographic mark present on the surface (S) of the construction to be provided with topographical marking information;
- a manual gripping means (MG) connected to a bearing element selected from the group consisting of the mobile printing carrier (MPC) and the ink printing head (1), said manual gripping means (MG) being adapted for manual gripping by a hand of the operator so as to enable the operator (a) to push the mobile printing carrier (MPC) towards the frame (F), whereby pushing at least one part of the said frame (F) on the surface (S) of the construction to be provided with said at least one topographical marking information, as well as (b) to move the mobile printing carrier (MPC) with respect to the frame (F) following the guiding means (6) for guiding the linear movement of the mobile printing carrier (MPC);
- at least one control means (5) for controlling the at least one marking information to be printed within the marking zone, said control means emitting gap information of a gap existing between (*) an actual position of the ink printing head (1) relative to said surface (S) of the construction to be provided with said at least one topographical marking information, and (*) a desired position of the ink printing head (1) relative to said surface (S) of the construction to be provided with said at least one topographical marking information, when the ink printing head (1) is in front of a portion of the marking zone to be provided with said at least one topographic marking information, and
- an activating means (AM) for activating the ink printing head (1) when the ink printing head (1) is in front of said portion of the marking zone to be provided with the at least one topographic marking information, so that the ink printing head (1) is adapted to print said at least one topographic marking information in the said marking zone, whereby said activating means (AM) is selected from the group consisting of (a) an activating means (AM) associated to the control means controlling the at least one topographic marking information to be printed, (b) an activating means (AM) associated to the manual gripping means (MG), whereby said activating means (AM) associated to the manual gripping means (MG) is mobile against a return mechanism with respect to the manual gripping means (MG), at least by exerting a pressure on said activating means by at least a part of the hand of the operator, and (c) a combination of said activating means (AM) associated to said control means controlling the at least one topographical marking information and said activating means (AM) associated to the manual gripping means (MG).
