Windows Printer Settings
There are some Windows command line statements that allow one to (i) identify the current Windows default printer (as well as other printers associated with a PC) and (ii) change the default to a different printer.
A program can use SHELL statements in QB64 to execute those operating system commands. See the following examples provided by forum member DonW:

- This code issues the command to display a PC's list of printers and routes the output to a text file:
SHELL _HIDE "CMD /C" + "wmic printer get name,default > default.txt"
A sample of the contents of the resulting file is as follows. Notice that the default printer is listed as "TRUE":
Default Name FALSE Microsoft XPS Document Writer TRUE HP Photosmart C7200 series FALSE HP Officejet Pro 8600 FALSE Fax
- Here is the code to set the default printer to the "HP Officejet Pro 8600" listed in the sample above:
SHELL _HIDE "CMD /C" + "wmic printer where name='HP Officejet Pro 8600' call setdefaultprinter"
Then running the get default SHELL code again, we see the following contents of the text file:
Default Name FALSE Microsoft XPS Document Writer FALSE HP Photosmart C7200 series TRUE HP Officejet Pro 8600 FALSE Fax
Now we see that the "HP Officejet Pro 8600" is marked as "TRUE", and thus is now the default printer for LPRINT and _PRINTIMAGE.
Notes
- These SHELL commands work in Windows XP, 7, 8.1 and 10.
