In this case, you have to change your application (ex. cancel transmitting the restricted command, or use another method [using specific command]).

How to use right side up printing
There are two methods for
right side up printing:
Note:
We recommend the “Using specific command“ method.
Using specific command method
In this method, host PC has to transmit two extra commands. A host PC must transmit the
“Start reverse block“
command at the beginning of right side up printing. After transmitting
the command and print data, the host PC must transmit the “End reverse block“ command
at the end of right side up printing.
This method requirse programming of the application program; however, this is the best
method.
Using DIP switch setting method
In this method, the host PC must transmit a paper cut command (ex.
GS V
) at end of
printing to print. However, this method has a few limitations:
•
The host PC is forbidden to transmit some ESC/POS commands.
(See “
Forbidden/Restricted commands for right side up printing mode
” on page 8.)
•
This method isn’t guaranteed on TM-U220 Type D (It doesn’t have an autocutter.)
If your application programming uses a paper cut command already, this method may
provide you right side up printing without changing the application program.
However, you should confirm that the host PC doesn’t transmit any forbidden commands. If
the host PC transmits a forbidden command to the printer, the printer may print incorrectly.
In this case, you have to change your application (ex. cancel transmitting the restricted
command, or use another method [using specific command]).
Note:
When you use this method, don’t transmit the specific command to the printer. If you do so, the
printer may not work correctly.
Method:
using specific
command
Advantage
Any application program can use this method
because this method controls the printer with a
command.
Disadvantage
You have to arrange the application program to
transmit the specific command.
Method:
using DIP
switch setting
Advantage
This method may provide you ì right side up printingì
without changing your application.
Disadvantage
If your application transmits a prohibited command,
the printer may not print correctly.
