TM-295 mode emulation cautionary items

Since, as shown below, the paper feed pitch, dot pitch and the installation
distances between the TOF/BOF sensors and the print head differ depending on
the mechanism of the SCP700 slip and TM-295, the printing results may not be
the same because of the differences in the mechanism. Also, even though, since
the TM-295 is a shuttle printer, the paper feed set values and actual paper feed
amount are different.

<Influence and command differences due to differences in paper feed motor
pitch and horizontal/vertical dot pitch>
Since the pitches are different, the printing results are reduced in the vertical/
horizontal direction compared to the TM-295. Especially in the page mode,
since the coordinates are controlled in dots, the printing results are reduced.
(There is a difference of n/60" dots - n/72" dots in the Y direction.)
In the case of the line mode, since the difference in the paper feed pitch is
absorbed as much as possible, the commands which are connected with the n/
60 inch unit paper feed (<ESC> "3" n, <ESC> "J" n, <ESC> "K" n) use
INT((6n/5)+0.5).
However, since even in this case, depending on the value of n, the paper feed
amount may not be exactly the same, the vertical direction printing position may
be different.
