Pardon me if this is an old subject but I haven't found an answer to this problem:
I am trying to use the Toner Transfer method to etch PCBs, so I need to generate one accurate printable plot of F.Cu and F.SilkS, mirrored and merged onto one single page for printing, and another accurate printable plot of B.Cu & B.SilkS, unmirrored and merged onto one single page for printing.
I have tried every combination of print and plot option without success. The problem is that print to PDF, which does offer both mirrored and print to a single page, previews correctly but as printed it has missing pads, and each of the plotting formats either has missing pads or incorrect pad sizing when printed. The problem is apparent with multiple components, but all are unaltered footprints from the library that comes with Kicad, using the same options. The problem is shown in the attached screen captures.
What is the correct way to merge F.Cu and F.SilkS onto one printed page, mirrored and accurately aligned, with correct and complete pad sizing, suitable for Toner Transfer? It looks like the only way is to plot individual layers to individual PDF files, then load them as individual layers into a bitmap graphic editor like Gimp, change the background to transparent, and then print as a bitmap rather than as a vector image.
Kicad version 2017-09-19 rev. dddaa7e69-makepkg, release build for Win7-x64
(for ngspice support).
Again, sorry if this is a newbie user error but this looks like a print & plot bug to me...
