sorry for the late entry but I am having similar problems with my new printer -? ?it prints the manifests but in minuscule fonts.
then printer is an HP 2600 and is the default printer
computer is an? Acer running win 10 and the jmri is V4.11 i think.
All other devices in the house print fine
from above discussion it looks like the quick fix would be to print to a pdf.? Not quite sure how to get this done,
As always, thanks for your help
