Print driver store for redirection printing in a virtualized computing environment

1. A method to use a print driver store to provide print drivers to a host device that runs a virtual desktop in a virtualized computing environment, the method comprising:

receiving, by the host device from a client device when a virtual desktop infrastructure (VDI) connection for a VDI session is established between the client device and the host device, printer information that identifies a physical printer coupled to the client device, wherein a native print driver for the physical printer is installed at the client device;

determining, by the host device, whether the native print driver for the physical printer is locally installed at the host device;

in response to determining that the native print driver is missing from the host device and in response to unavailability of an installer kit, at the client device for the native print driver, which causes the native print driver to be unable to be installed at the host device by being provided from the client device, searching, by the host device, the print driver store for the native print driver;

in response to locating, by the host device, the native print driver in the print driver store, obtaining, by the host device, the native print driver from the print driver store and installing, at the host device, the native print driver obtained from the print driver store; and

instantiating at the host device, by the host device, a virtual printer corresponding to the physical printer and associating the installed native print driver obtained from the print driver store with the virtual printer.

2. The method of claim 1 , further comprising:

in response to failing to locate the native print driver in the print driver store, associating, by the host device, a universal print driver at the host device with the virtual printer; and

in response to determining that the native print driver is locally installed at the host device, associating, by the host device, the locally installed native print driver with the virtual printer rather than searching for the native print driver in the print driver store.

5. The method of claim 4 , wherein the first repository is a pre-public repository with limited access privileges, and wherein the second repository is a public repository.

6. The method of claim 1 , wherein the native print driver is persistently stored at the host device after installation, including remaining persistent after the virtual printer is deleted.

7. The method of claim 1 , further comprising:

in response to determining that the native print driver is installed at the client device and is usable at the host device:

installing at the host device by using the at least one print driver file, by the host device, the native print driver;

instantiating at the host device, by the host device, the virtual printer corresponding to the physical printer, and associating the native print driver installed using the at least one print driver file received from the client device with the virtual printer; and

using, by the host device, the native print driver installed using the at least one print driver file received from the client device to generate print data from a print job issued from the virtual desktop so as to enable the print data to be directly passed to the physical printer coupled to the client device for printing.

8.

searching, by the host device, the print driver store for the native print driver;

in response to locating, by the host device, the native print driver in the print driver store, obtaining, by the host device, the native print driver from the print driver store and installing, at the host device, the native print driver obtained from the print driver store; and

instantiating at the host device, by the host device, a virtual printer corresponding to the physical printer and associating the installed native print driver obtained from the print driver store with the virtual printer; and

in response to determining that the native print driver is installed at the client device and is usable at the host device:

receiving, by the host device from the client device, at least one print driver file corresponding to the native print driver installed at the client device;

installing at the host device by using the at least one print driver file, by the host device, the native print driver; and

instantiating at the host device, by the host device, the virtual printer corresponding to the physical printer, and associating the native print driver installed using the at least one print driver file received from the client device with the virtual printer.

9. The non-transitory computer-readable medium of claim 8 , wherein the method further comprises:

in response to failing to locate the native print driver in the print driver store, associating, by the host device, a universal print driver at the host device with the virtual printer.
