Abstract

Network scanner software that accesses scanners over a network to remotely scan a document. Once a scanner is reserved, no other computer system can access the scanner. The computer system to which the scanner is connected changes the appearance of an icon representing the scanner to indicate that the scanner is reserved. If a user of the computer system moves the cursor over the icon, a pop-up window is displayed with the name of the computer system that has the scanner reserved. Once a scanner is reserved, a user may place a document into the scanner, push a button on the scanner, whereupon the scanner scans the document and sends the scanned data to the computer system that reserved the scanner. A user may reserve a scanner, start a timer, and when the timer expires, the document in the scanner is scanned and the data returned to the computer system.

Claims

1. A computer implemented system for remotely scanning a document, the system comprising:

means within a local computer system for displaying a selection screen to allow a user to select a scanner located on a remote computer system;

means for sending a reserve request from the local computer system to the remote computer system, wherein the scanner is reserved for exclusive use of the local computer system;

means for starting a local application program in the local computer system;

means for receiving a scan command from the local application program and sending the scan command from the local computer system to the remote computer system;

means for scanning a document into the remote computer system from the scanner to produce scanned data;

means for returning the scanned data to the local computer system; and

means for copying the scanned data into the local application program.

2. The system of claim 1 wherein the means for sending a reserve request further comprises:

means for determining, in the remote computer system, whether the scanner has been previously reserved by a second local computer system;

means for reserving the scanner for the local computer system when the means for determining whether the scanner has been previously reserved determines that the scanner has not been reserved by a second local computer system; and

means for returning an error indication to the local computer system when the means for determining whether the scanner has been previously reserved determines that the scanner has been previously reserved by a second local computer system.

3. The system of claim 2 further comprising:

means for altering an appearance of an icon representing the scanner on a display device connected to the remote computer system, wherein an indication that the scanner is reserved is presented to a user of the remote computer system.

4. The system of claim 1 further comprising the step of:

means for displaying a name of the local computer system on the display screen of the remote computer system when a user of the remote computer system moves a cursor on a display screen of the remote computer system over an icon representing the scanner of the remote computer system.

5. The System of claim 1 wherein the means for scanning a document into the remote computer system further comprises:

means for delaying the scanning of the document until a signal is received indicating that a scan button has been pressed on the scanner.

6. The method of claim 1 wherein the means for receiving a scan command further comprises:

means for delaying the sending of the scan command for a time defined by a timer value set by the user, and sending the scan command after the amount of time specified by the timer value.

11. The method of claim 1 wherein step (e) further comprises the step of:

(e1) delaying the scanning of the document until a signal is received indicating that a scan button has been pressed on the scanner.

12. The method of claim 1 wherein step (d) further comprises the step of:

(d1) delaying the sending of the scan command for a time defined by a timer value set by the user, and sending the scan command after the amount of time specified by the timer value.

7. A method of remotely scanning a document, the method comprising the steps of:

(a) displaying a selection screen to a user on a local computer system to allow the user to select a scanner located on a remote computer system;

(b) sending a reserve request from the local computer system to the remote computer system, wherein the scanner is reserved for exclusive use of the local computer system;

(c) starting a local application program in the local computer system;

(d) receiving a scan command from the local application program and sending the scan command from the local computer system to the remote computer system;

(e) scanning a document into the remote computer system from the scanner to produce scanned data;

(f) returning the scanned data to the local computer system; and

(g) copying the scanned data into the local application program.

8. The method of claim 7 wherein step (b) further comprises the steps of:

(b1) determining, in the remote computer system, whether the scanner has been previously reserved by a second local computer system;

(b2) when step (b1) determines that the scanner has not been reserved by a second local computer system, reserving the scanner for the local computer system; and

(b3) when step (b1) determines that the scanner has been previously reserved by a second local computer system, returning an error indication to the local computer system.

9. The method of claim 8 wherein step (b2) further comprises the step of:

(b2a) after reserving the scanner for the local computer system, altering a color of an icon representing the scanner on a display device connected to the remote computer system, wherein an indication that the scanner is reserved is presented to a user of the remote computer system.

10. The method of claim 7 further comprising the step of:

(h) when a user of the remote computer system moves a cursor on a display screen of the remote computer system over an icon representing the scanner of the remote computer system, displaying a name of the local computer system on the display screen of the remote computer system.

13. A method of scanning a document, the method comprising the steps of:

(a) displaying a selection screen to a User on a local computer system to allow the user to select either a local scanner located on the local computer system or a remote scanner located on a remote computer system;

(b) when the user selects a remote scanner in step (a) sending a reserve request from the local computer system to the remote computer system, wherein the scanner is reserved for exclusive use of the local computer system;

(c) when the user selects a local scanner in step (a), reserving the scanner attached to the local computer sytem;

(d) starting a local application program in the local computer system;

(e) receiving a scan command from the local application program;

(f) when the local scanner has been selected, sending the scan command to the local scanner;

(g) when the local scanner has been selected, retrieving scanned data from the local scanner and proceeding with step (k);

(h) when the remote scanner has been selected, sending the scan command from the local computer system to the remote computer system over a computer network;

(i) when the remote scanner has been selected, scanning a document into the remote computer system from the scanner to produce scanned data;

(j) when the remote scanner has been selected, returning the scanned data to the local computer system; and

(k) copying the scanned data into the local application program.
