* Text printing (built-in fonts), page mode, and monochrome graphics printing.
The print speed changes automatically depending on the voltage applied to the printer and the
condition of the head temperature.
Maximum print speed may not be achieved depending on the type of interface, data transmission
conditions and combination of commands.
If the print speed fluctuates or intermittent printing occurs due to the data transmission
conditions, printing may be shaded or white lines may occur.
Low transmission speed may cause intermittent printing, especially when using a serial interface. It
is recommended to transmit data to the printer as quickly as possible.
The following conditions specify the maximum print speed regardless of the print density and
paper width settings.
The maximum is 100 mm/s {3.94"/s} when printing ladder barcodes or two-dimensional sym-
bols.
The maximum is 150 mm/s {5.91"/s} when printing multi-tone graphics (NV download graphics).
The maximum is 70 mm/s {2.76"/s} when printing multi-tone graphics (raster graphics).
When changing the paper width, you need to install the optional 58 mm paper guide (PG-58II) and
to change the setting for the paper width with the customized value. To change the paper width,
see
"Software Settings" on page 60
.
Because some parts of the print head and the autocutter contact the platen and they may become
worn out in 58 mm printing, once you change the paper width from 80 mm to 58 mm, you cannot
change it back to 80 mm.
