Escape codes fo Epson POS

rbuser

I tried to use the control font P size 10 to make a cut on a POS printer
Tmu220. It cut the paper but it advance the paper where the code is instead
of cuting when it recieve the command. What happen is that there is a paper
feed I don't want. If I use the g with the control fornt it cut the paper
but I know this font is used to make the printer primt the graphic on the
printer that was uploaded to it's memory so there is a potential problem
using this. There is on the Epson POS manual a command to set the way the
printer cut tha paper. Depending on thos codes it will feed the paper where
the font is to the cutter or make the cut at the moment the character is
sent to the printer. The GS V is the command to how the printer will make
the cut . There is a manual that shows the codes for the Tm U220

I need to controll this printer so I can controll the way it cut the paper.

Thanks

Hi Carlos,

ReportBuilder renders to the printer using the Delphi TCanvas class and via
calls to Windows GDI functions.

We do not have any direct experience with sending escape codes directly to
the printer driver. According to the Windows API documentation, the
ExtEscape function allows applications to access capabilities of a
particular device that are not available through GDI. Try searching the
Windows API docs and Google for more information.

Tech Tip: Configuring Printer Specific Options
-------------------------------------------------

The Report.PrinterSetup properties can be used to set the properties that
are common to all printers. Internally RB applies these to the Windows
DevMode structure.


Report.PrinterSetup <----> Windows DevMode <-----> Printer Driver <--->
Printer


Printers often contains additional features, such as output bins, media
types, etc. The Windows DevMode structure can contain a private area that is
used the printer driver to store printer specific options. These can be
configured by using the Printer Driver's built-in properties dialog. These
options can theoritically be set programmatically, the trick is that you
have to know where in the structure to store the option and what values are
valid.

The following example shows how to display the printer properties dialog and
save the devmode for use within RB...
