Win 7 can do this without any "helper applications" - Skip steps 2 and 3 if your printer's default settings are OK for the job.
- From the Start Menu, select Devices and Printers.
- Locate the printer you'll print to, and right-click. Select Properties.
- Change any default settings to the settings you will use for this print job.
- Now, double-click the printer to open the print queue box.
- Drag whatever files you wish to print into the print queue box. They can be mixed file types such as pdf and docx.
- A dialog box confirms that you want to print multiple files at once - click OK.
That's it - your documents should start printing immediately.
This is a pretty annoying feature in Win7 - I realize it is done to keep casual users from crashing their systems, but it would be really helpful if the 15 file limitation could be turned off for those who have a print server and a grip of ram!
If anyone knows how to hack the registry to change this, please share.
In HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
create a DWORD (32-bit) Value called MultipleInvokePromptMinimum.
Doubleclick this new entry an select decimal. Enter 16 in the textbox.
This should show the Open, Edit, Print menu items regardless of the amount of selected files.
