Abstract: One computer-implemented method comprises receiving requests to create subforms associated with a digitally stored expense trip preapproval form; in a particular subform, receiving input specifying input values for attributes of the particular subform, the plurality of input values collectively specifying the travel expense item; programmatically transmitting, to a price modeling server, a query comprising the input values and requesting a cost value for a travel item corresponding to the input values, and receiving a predicted cost of the travel expense item; automatically updating the particular subform to display the predicted cost and to populate the predicted cost into a total cost attribute, the total cost attribute being separate from the predicted cost; receiving an updated value of the total cost attribute and updating it; in response to determining that the updated total cost attribute differs from the predicted cost, presenting a notification specifying an amount of the difference.

Abstract: In one embodiment, a computer-implemented method executed using a server computer comprises receiving from a user computer via a network one or more requests to create one or more subforms that are associated with a digitally stored expense trip preapproval form, each of the subforms being associated with a different type of a travel expense item; in a particular subform among the one or more subforms, receiving input from the user computer specifying a plurality of input values for attributes of the particular subform, the plurality of input values collectively specifying the travel expense item; programmatically transmitting, to a price modeling server, a query comprising the plurality of input values and requesting a cost value for a travel item corresponding to the plurality of input values, and receiving in response to the query a predicted cost of the travel expense item; automatically updating the particular subform to display the predicted cost in the particular subform and to populate the predicted c

Abstract: A printing apparatus with capability for drying printed media is disclosed. The printing apparatus includes a print zone and a post-printing zone, an advancing mechanism for transporting the print medium through the print zone, a print head for ejecting ink onto the medium as the medium is being transported through the print zone, and a heating system for drying the ink ejected onto the medium. The heating system includes a plurality of thermoelectric modules positioned in the print zone or the post-printing zone. Each thermoelectric module has a heat-rejecting surface and a cooling surface. The heat-rejecting surface of each thermoelectric module is positioned to face the medium being transported.
