About the print format control and the width of the paper

1 inch is about 2.54

The parameters set for the printing control are for inches.

The font setting is too large to exceed the line spacing (this may also cause incomplete printing)

The row and column calculation method is as follows:

Len/2.54 * per

Len indicates the actual length or width.

Per is the number of rows and columns per inch.

Possible \ e is the identifier l7.5: Line 7.5; c15.0 Column 15.

Therefore, this printing and development program for Electrical Appliances

Zm006n: 21.5/2.54*15 = 126 margin not taken into account, so the actual length of printing must be controlled in the 120 Column

Zm269: 21.5/2.54*17 = 143 considering that the margin is controlled within 135

So after these two programs have been adjusted for so long

Mistaken hitting has actually reached a relatively reasonable value

This range can be determined from the very beginning.

Appendix:

The number of lines per inch in LPI, used to indicate the size and spacing of Characters in the vertical direction.

The number of pages printed per minute by ppm (papers per minute). This is an important parameter for measuring the printer's printing speed and the average speed during continuous printing.

The number of characters contained in the CPI (characters per inch) per inch, used to indicate the character size and spacing.

(This is the log recorded in Evernote at the time of development, and I think it is okay to write it.

I wrote a detailed article about the print control, which was actually referenced by Hua ting huijian during the development at that time.
