#Librecad drawing twice size drivers

In your case the information from the printer driver seems to be wrong.ĪutoCAD's calibration feature I think uses the calibration data to generate an incorrect memory drawing to compensate the printer drivers malfunction. With this resolution the drawing is generated in memory and shifted to the printer driver. When printing LibreCAD or more precisely the Qt library requests the printer driver for information about its physical resolution. LibreCAD uses Qt's printing capabilities, so it is platform independent. When AutoCAD has this calibration feature, there must be some printer and plotter out there which have the same problem. I've tested your issue with two HP Laser printer and both results was OK. To your problem, this is certainly caused by the printer driver. You have contacted the developers already, they are present here in the forum.

#Librecad drawing twice size pdf

I print in pdf many times because of my 'job', and I never had problems, if you are under linux then it should be some postscript option when you print, if you are using a Mac try to find a PDF printer even in this situation, I never used a Mac, sorry. If it is a problem of the printer itself (I hope for you that is not the case), try to print in PDF, if you are under windows I use 'doPDF' printer, so I can set the paper size, the PDF dpi and some other stuff. Or maybe you can find out that paper size is wrong, so try to check it! Try to see first the print preview and its options, Imean scale, b/w print and so on.

How can I solve that with problem LibreCAD? I calibrate the printer with autocad and all future prints are correct. With autocad I can solve it as shown in my first email. That is a problem in the communication between LibreCAD and the printer. I am unlucky, as in height the printed dimension is ok, 270mm, but in width it is not! In width I get 1.5mm less. If the dimensions of your printed lines are ok you are lucky. Then take a mm-ruler and measure the printed lines on the paper. To select a scale will not solve the problem.ĭraw a rectangle with LibreCAD e.g.
