Calibration

[PezO]

I need to calibrate my  HP DesignJet T120 24-inch to get the right size in the prints. When I print 1000mm it comes out as 1009mm. How do I fix this? 

I use Win 10 OS and Layout from SketchUp.

I think it's more related to Sketchup than the specific printer. Seems to be a common grief.

Googling for sketchup printing 1:1 brings a lot of hits and hints.

I don't have the Pro version of SketchUp but one option would be to export as DXF and use a 2D CAD program like DraftSight (free version is good) to print and process further if necessary.

Thanks jorkki for your reply.

After a few hours of trial and error I found out that it was the document size settings in the printers folder in the os that was the clew. It´s just so frustrating to having to go through a hole investigation to do something so basic as to print out a simple drawing. You have to make one preset paper-length template for every commonly used drawing size in the print server properties box.

But there you are when you don´t have a master in computer science, just the simple knowing how to make a curved staircase whith tangent (3-d curved) handrailing irl...

Handling Layout is also one challenging task!

Good that you got it sorted.

Unfortunately it is so with computers a lot of the time..just look at the number of messages on this forum alone.

Please do select your own message as the solution, so others may find it easier.

To be useful as a solution we need a summary:

Calibration simply was not needed when I skipped going through PDF, but going straight to the printerfolder instead, but I had to make some new customized setups in the folder. Now the calibration is pd accurate! And I dont have to use a plugin or PDF. -Simple!

Printing a big drawing to a rollpaper printer/plotter from Layout in PC (may be applicable for other programs, I don´t know..) 

Go to Control panel - Devices and printers.

In the top of the folder, choose the tab for "Print server properties"

Click the box for "create a new form"

Give your form a name in the dedicated box.

Type the measurements in the boxes. (In my case 24" for width all of the time, but different lengths)

Dont forget to save your form by clicking the save button.

exit

Now you can choose your new format in the rollist that appears when you push the print button in the original program. The default setting seems to be landscape format, so you have to choose portrait instead.

 (I made form intervalls whithin 10cm , gave them name 10 for 100cm print , 11 for 110cm print etc. )

Hope this was useful for someone! Cheers /P

Forgot to mention;

How is this related to my original question,calibration?

Well, I started out trying to print via acrobat pdf, as I found it tricky straight throug the printfolder, and some forums recommended that way. Then I had the issue whith printout altering the scale.

Sorting out the printfolder solved the problem, and now the prints are pd. accurate! I dont need an extra path via plugin or pdf, so the process is simple and fast!
