I have been trying to use your Envelope Printer - currently tested to v1.5.0. I am attempting to print a US #10 envelope (4 1/8" x 9 1/2") on a Brother MFC-9840CDW Color Laser Printer. I am utilizing the manual tray. All things seem fine up until I actually print. The printer takes the envelope from the manual tray and then gives a "Check Paper Size" error on its LCD display. If I should then place an 8 1/2" x 11" sheet of paper into the manual tray, it will print without error - However, the position of the printing will NOT be correct. If an envelope is placed over the area that it would have occupied, the printing is good for the envelope top to bottom, but starts 5 1/4" from the left edge. If I should have the program "Auto Select" the Paper Bin, then print to an 8 1/2" x 11" sheet of paper, it again seems good top to bottom, but starts 6 1/2" from the left. I have tried to "tweak" the sizes.dat file - to no avail.
I do not experience any printer problems when printing from other programs - even when printing to this same envelope size from the manual tray.
Additionally, the "Print Quality - DPI" shows "(0 Total)" and the drop down provides 0 choices. Yet, the printer does print and does have several choices of quality settings.
My System: Windows 8.1 Pro with Media Center x64 with all updates installed
I am more than happy to experiment - just point me to what you would like me to try ...
Thanks,
Will Friend
