How to show available printers and print file

I need to send a binary file to a printer within a C++ program. Is there a way other than the 'system lpr' method? Currently I open a printer as a shared printer (\\computer-name\share-name) and this works ok, but is somewhat cumbersome when printers are added or changed. Looking for a way I can display the available printers, have the user select one, and then send the files to the selected printer.

Use the PrintDlgEx API to show the Print dialog.
Here the user can select the printer of choice and also set its various properties.
After the user selects a printer to print, the PRINTDLGEX structure parameter to PrintDlgEx will contain a device context handle to the selected printer in its hDC member.
Printing to the selected printer is then just a matter of drawing to that printer device context.

Thanks, I will try the PrintDlgEx method. However, I am concerned that the file will be corrupted by the windows driver. The files I send to a printer must be a bit for bit transfer.

I found this link[^] which suggests that there was a method in the days of Win-95/NT, but I cannot be sure that it still works now; perhaps still worth investigating.
