I guess you can change fonts using control characters but I don't know if you can embad tham in a word doc. No way to test it because I don't have this printer.I remember having done it in early days of DOS word processing with Wordstar.

Hold ALT and type the command character - the numbers 27. In notebook will look like an arrow to the left, followed by writing a command character, examples:
? P Selects 10 cpi
? M Selecting the 12 CPI
? ? Select dense Print - 15 CPI (this character is typed by holding the ALT key figures 15)

Try to find the characters in internet and then print them using pdf document oor any type.

The following links give you few Chinese characters.

Make sure you have the right driver (ie mx80). Only one or two drivers will work well in dos. It may also need a string added to the report to force it to go to the dos printer. Another thing that can affect size is the font size or font size must be placed in the header of the report.

Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine-encoded text.
These can be scanned in a word processor or other programs, then can be modified.It is software usually include with your Printer/Scanner

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response.

A character set is presented with which unscaled 2D molecular structural diagrams can be constructed. A minimal subset has been implemented in ROM on CBM microcomputers, whilst the complete set has been defined as a character font on an ICL PERQ computer. Structural diagrams have also been output on dot-matrix and daisy-wheel printers using appropriate software to print the special characters. The character set provides a simple means of displaying molecular structures on inexpensive microcomputers, on printers and on hardware offering user-definable character fonts.

if you are seeing letter or print ghosting the printhead might need to be replaced.

Sounds like there is something corrupt with the driver or the wrong driver is associated with the printer. Delete the printer from the computer, but leave attached. Download the newest driver directly from Lexmark and execute the download. The computer should then automatically re-install the printer.
