GP strip printing cannot be installed independently. GP strip printing is part of the GP Manager and is added during its installation.

With the GP moulding printing module, you prepare your designed mouldings for the printing process. The lasts you have created on the basis of a measurement are transferred to the GP last printing module as a print job. In the GP last printing module, you have the option of changing the pitch of the last or trial shoe and defining and positioning the connecting elements of the last. The generated data is then sent directly to the printer or optimised for the printing process using the "Simplify3D" program. The lasts or trial shoes are then printed by the printer.

To open the GP moulding printing module, click on the "GP moulding printing" icon in the module overview. You do not need to have selected a customer for this.

The module interface consists of the menu bar (1), the order list (2), the workspace (3) and the function bar (4).

If you have not selected a customer after starting the GP Manager, the following will be displayed in the menu bar:

The arrow (1) takes you back to the module overview. If you have problems or questions about the GP Manager, you can click on the question mark (2). This will take you directly to our support homepage.

The job list displays all print jobs that were created in the GP CAD module. From left to right, the list shows you the date the job was created, the customer's surname and first name and the type of print job (last or trial shoe). Click on the order to select it and display it in the workspace.

By clicking on one of the column headings, you can sort the list according to the selected column. By default, the list is sorted by the time the job was created, with the oldest print job at the top of the list and the newest print job at the bottom.

To move the list up and down, click once in the list with the left mouse button and move the mouse up or down while holding down the mouse button.

By ticking the "Completed jobs" box, all completed print jobs are displayed.

The lasts or trial shoes are displayed and processed in the workspace.

Once you have selected a print job, it is displayed in the workspace. In the job list, the date the job was created, the customer's first name and surname and the print job are displayed from left to right. The active job is highlighted in blue.

In the workspace, you have the option of editing the cut and the connecting elements.

The function bar is located on the left-hand side. From top to bottom, you can first select the printer used, choose between different combinations of connecting elements, switch between views and create the print file.

The exact handling of the individual functions is explained in the next section.

By clicking on the order in the order list, the last or trial shoe is displayed in the workspace.

If the print job for a test shoe is selected, the following view is displayed:

The test shoe is divided into three parts for the printing process: Toe (red), heel (green) and leg (blue). The entire trial shoe is shown on the right-hand side. The orange triangles mark the cutting lines where the trial shoe is divided. The cuts can be moved by clicking on one of the triangles. In the leg area, the height (in mm) at which the height of the trial shoe is cut off is displayed on the cutting line.

On the left-hand side, the individual test shoe parts are displayed as they are positioned on the print bed. The black line above the parts indicates the maximum print height of the printer.

If the print job for a moulding is selected, the following view is displayed:

The last is also divided into three parts as standard: Toe (red), heel (green) and leg (blue). When the last print job is called up, the individual elements of the last are displayed on the left-hand side as they are positioned on the print bed.

The entire moulding is also shown on the right-hand side. In addition to the cutting lines, connecting elements are also drawn in so that the moulding parts can be joined together. These must also be positioned. The description of the individual elements and the special features of positioning are described in more detail in chapter 4.

To place the last or trial shoe anywhere on the work surface, use the following key combinations and mouse movements:

Key combination Mouse movement in the direction of the bar

CTRL key + left mouse button horizontal right or left

CTRL key + left mouse button vertically up or down

To view the last or trial shoe from any perspective, click in the workspace and rotate it with the mouse. The direction of rotation is determined by the following key combination and mouse movement:

Key combination Mouse movement Rotation

SHIFT key +left mouse button rotate all directions freely around all axes

Press the "L, R, O, U, V, H" buttons in the function box to return to the standard views.

When the moulding is rotated, it loses its transparency so that you can no longer see the connecting elements within the moulding. By turning the moulding, however, you can judge where a connecting element is still protruding from the moulding.

You can zoom the last or trial shoe on the work surface using the following key combination:

Zoom key combination

Mouse scroll wheel smaller/greater (pointer must be in active window)

The individual buttons and functions of the function bar are explained in more detail below, from top to bottom.

If you have selected a print job from the job list, you will be shown whether a trial shoe or a last is to be created. Accordingly, the button for the trial shoe or last is highlighted in dark grey.

If you have sent a print job for a trial shoe even though a last is to be produced, you can use these buttons to switch between the two print forms.

The 3D printer for which the print file is to be created is selected in the top list of the function bar. By default, your printer should be highlighted in blue in the list and therefore selected. If you have several different printers, you should ensure that the correct printer is activated when generating the print file.

You can assign your printer to our product designations in the following overview:

If the correct printer is not set by default, you can change this setting by going to the "GP Admin" module in the module overview:

Then open the "INI settings":

The following window opens:

The correct INI must be selected in the drop-down menu: GP_CAD_LEISTENDRUCK

Then double-click on the "Printer" parameter:

Now select the "I_Standard" parameter:

You can now enter the corresponding parameter in the field on the right-hand side (red arrow). The "1" stands for the LP 333, the "2" for the LP 222, the "3" for the LP 322 and the "4" for the LP 433. The corresponding parameter is saved by clicking on "OK". If you now reopen the "GP LeistenDruck" module, the change should take effect immediately. Otherwise, please restart the GP Manager.

When printing the moulding, you can choose between four sets with different connecting elements. The selected set is highlighted in blue.

The set "Standard" divides leg slats into three parts as standard: toe, heel and leg. The toe and heel parts, as well as the heel and leg parts, are each connected to each other using two metal pins and two screws. Low shoe lasts are divided into two parts: Toe and heel.

With the set "Basic", leg lasts are also divided into just two parts: toe and heel. The two parts are also joined together using two screws and two pins. This set is recommended if you want to print leg mouldings with a low height.

The set "Robust" should be used if your lasts are exposed to greater loads during shoe production, e.g. from a lasting machine. In this set, the leg lasts are divided into three parts as in the "Standard" set. However, in addition to the two pins and screws, two channels are built into the tip, in which you can install threaded rods to increase the stability of the last.

With the set "Kids", there is only one opening for one connecting screw and one connecting pin between the individual parts. This set is recommended for small, narrow mouldings.

If you want to change the stand selection of the set, go to the "GP Admin" module in the module overview:

Then open the "INI settings":

The following window opens:

The correct INI must be selected in the drop-down menu: GP_CAD_LEISTENDRUCK

Then double-click to select the "Elements_Sets" parameter:

Now select the "I_Standard" parameter:

You can now enter the corresponding parameter in the field on the right-hand side (red arrow). The "1" stands for the "Standard" set, the "2" for "Basic", the "3" for "Robust" and the "4" for the "Kids" set. Click on "OK" to save the corresponding parameter. If you now open the "GP LeistenDruck" module again, the change should take effect immediately. Otherwise, please restart the GP Manager.

The following buttons can be used to switch between the individual views:

Use the "Left" and "Right" buttons to switch between the left and right bars.

NOTE: Please ensure that you first create the print file for one page before switching to the other page! Otherwise the settings and customisations will not be saved!

You can use the "O, U, L, R, V, H" buttons to view the moulding from different perspectives:

O - from above

U - from below

L - from the left (you can see the left slat from the outside and the right slat from the inside)

R - from the right (you can see the left moulding from the inside and the right moulding from the outside)

V - from the front

H - from behind

With the buttons "Total", "Toe", "Heel" and "Leg" you can either view the entire last / trial shoe or switch between the individual parts, such as toe, heel and leg.

The "Create print file" button is used to create the print file for the page currently displayed. The progress and finally the storage location of the file are displayed below the button.

NOTE: Please note that you create the print file for the edited page directly before switching to the view of the other page.

Once you have created the print file for both pages, click on "Completed". The print job is then marked as "completed" and removed from the current job list.

If you tick the "Completed print jobs" box, you can reload the print job into the workspace for processing.

1. open the "GP LeistenDruck" module
2. select the print job from the job list on
3. a Low shoe lasts is displayed in two parts as standard:

Pull on the orange arrow on the plantar surface of the trial shoe (p. red arrow) to change the cut

NOTE: When positioning the cut, you should ensure that the individual parts are not positioned too flat on the print bed. For example, the plantar surfaces should have an angle of at least 45° to the print bed.

4. a Leg mouldings is divided into three parts as standard:

Pull on the orange arrows to change the cut. The upper orange arrow shows you the height of the leg last. Also make sure that the cuts are not too shallow when making the leg last.

NOTE: You can also print a leg last in two parts by also pulling the cut between the leg and heel up to the cut of the leg. However, always pay attention to the positioning on the print bed.

1. open the "GP LeistenDruck" module
2. select the print job from the job list on

In the following, the processing of a leg last with the "Robust" set is explained; the processing can be transferred to the other sets and half shoe lasts:

3. In the first step, adjust the cuts of the individual parts:
   • Pull the upper orange arrow on the leg to the desired height
   • Drag the orange arrow on the plantar surface of the last to change the cut

NOTE: Also make sure that the cut is not too shallow. The plantar surfaces should have an angle of at least 45° to the print bed, for example.

• Changing the screws:

• Changing the pins:

• Changing the threaded rods:

• Changing the openings for moulding:

NOTE: Please also check the position of the individual elements in the other standard views and in the views of the individual parts

NOTE: Please ensure that individual openings do not overlap!

NOTE: The individual elements should be at least 3 mm from the edge of the moulding!

NOTE: The individual elements should lie within the moulding and not protrude from the moulding. The best way to check this is to turn the moulding.

 5. after you have positioned the elements, please click on "Create print file"

6. Switch to the right moulding and repeat the positioning of the elements and cuts

7. click on "Create print file"

8. once you have created the print file for both pages, click on "Done" and finalise the print job
