3- 6．Paper feeding
(1）Avoid deterioration by backlash feeding
Backlash in the paper feed mechanism may lead to under feeding and crowding of characters on
adjacent lines. Be sure to always turn the paper feed motor 24l steps（3mm）at the start printing
and initialization, and after opening and closing the thermal head.
（2）Notice on graphic printing
If the printer must wait for data from host systems while printing, it will temporarily stop printing
and feeding paper. After the printer receives new data and resumes printing, the paper feeding of
1 to 3 lines may become irregular, especially if it is printing a bit image. In graphic printing, you
may see irregular printing if the single lines of data are specified for Raster bit images.
Specify a minimum of 16 lines or more when graphic data is printed.
(3) About paper cut
To prevent the printer from paper jam, the printer automatically feeds the paper about 1mm
after cutting process. Therefore printing position is added 1mm to cutting position
