How do I send Escape Sequences to a Printer?

rbuser

I use Delphi 6 and RB6.01 My client has chosen NowDocs to provide the forms
we will be printing on. Basically, a check form, along with the signatures
are encoded on a DIMM module that is inserted into a printer. This form is
activated by sending an escape sequence to the printer.

Using Reportbuilder, I could use normal components to place the data onto
the page as I normally would. But I can't use a page style component
because we are not using image files on a PC, for security reasons. There
will be two different DIMM modules for our payroll (regular checks and
direct deposit advices), for example. How would I send an escape sequence
for printing the data and form on a single page?

Thanks in Advance!

Hi Debbie,

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.
