Need help, printer STAR SP700(SP712) USB interface, driver installed successfully, tapi saat test print sangat lambat....

Ane pake ZORIN OS 10 32bit

udah baca manual, dan memang ada issue untuk yang versi USB interface, print speed lambat, dan harus run script yang ada di dalam folder driver (download dari websitenya) untuk memory switching (ane kurang paham maksud dari memory switching di printer)

File nya seperti berikut, setup_for_linux.sh

#!/bin/sh
#
# Memory Swtich Setting Script for TSP650/TSP700II
#
# How to use:
#
# 1) Set TSP650, TSP700II as a Default printer
# 2) Copy this script (setup_for_linux.sh) and linux.dat into home folder.
# 3) Execute Termnal, then input "./setup_for_linux.sh" and return Enter key.
# 4) After execution, printer will print self test.
# Please verify print result of <C> line in "-- Memory Switch --" part.
# 3rd digit of the <C> line should be set to "1".
#
# Sample:
# <C> 0010000000000000 0200
#
lpr -o raw linux.dat
#
#
# Note:
# If you can not set SP650/TSP700II as a default printer, refer to the following
# procedure.
#
# 1) Using following command, printer queue lists, print queue names,
# and default printer will be displayed.
#
# $ lpstat -p -d
#
# dispaly example:
# star-no-power-mac-g4:~ star$ lpstat -p -d
# printer TSP651__STR_T_001_ is idle. enabled since Jan 01 00:00
# printer TSP743II__STR_T_001_ is idle. enabled since Jan 01 00:00
# system default destination: TSP743II__STR_T_001_
#
# "TSP651__STR_T_001_" and "TSP743II_STR_T_001_" are printer queue name.
#
# 2) Use following commands to set the selected printer.
# Input printer queue names into "Printer-queue name" according to "$ lpstat -p -d command".
#
# $ lpr -o raw linux.dat -P "Printer-queue name"
#
