Paper Feeding
Backlash
Backlash in the paper feed mechanism may lead to under-feeding and crowding of characters on
adjacent lines. Always be sure to turn the paper feed motor 24 steps (3mm) at the start of printing
and initialization, and after opening and closing the thermal head.
Graphic Printing
If the printer must wait for data from the host systems while printing, it will temporarily stop printing
and feeding paper. After the printer receives new data and resumes printing, the paper feeding for 1
to 3 lines may become irregular, especially while 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.
