a second head mounted display that is viewable by only a second user to conduct second work for the electronic device, the second work relating to the error of the electronic device; a memory configured to store computer-readable instructions relating to the first work and the second work; and a processor configured to execute the computer-readable instructions such that the processor is configured to: display a first work content of the first work on the first head mounted display and the first work content of the second work on the second head mounted display so that the first and second head mounted displays display the first work content; display a second work content of the first work on the first head mounted display when the processor is configured to display a work waiting content of the second work on the second head mounted display; and display a third work content of the first work on the first head mounted display and the third work content of the second work on the second head mounted display after the first user completes the second work content of the first work, wherein the first work content is different from the second work content and the third work content, and the second work content is different from the third work content, the work waiting content is a notification of a waiting state for the second user, one of the first work content and the third work content includes an indication of a start time at which the first and second users start one of the first work content and the third work content at the same time, and the first, second, and third work contents relate to a solution of the error of the electronic device. ### Claim 2 (depends on 1) The display system according to claim 1, wherein, when the first work or the second work has a plurality of work contents, the processor is configured to sequentially display the plurality of work contents on the first head mounted display or the second head mounted display. ### Claim 3 (depends on 2) The display system according to claim 2, wherein the processor is configured to switch the plurality of work contents which are displayed on the first head mounted display or the second head mounted display according to a state change of the electronic device. ### Claim 4 (depends on 2) The display system according to claim 2, wherein the processor is configured to receive an input manipulation for progress of the first work and the second work for the electronic device, and the processor is configured to switch the plurality of work contents which are displayed on the first head mounted display or the second head mounted display according to an input result of the progress of the first work and the second work. ### Claim 5 (depends on 1) The display system according to claim 1, wherein the processor is configured to detect a location where the first work or the second work is performed for the electronic device so that the processor is configured to display the location on the first head mounted display or the second head mounted display. ### Claim 6 (depends on 1) The display system according to claim 1, wherein the first work and the second work are different from each other. ### Claim 7 (depends on 1) The display system according to claim 1, wherein the indication of the start time that is displayed on each of the first head mounted display and the second head mounted display corresponds to a countdown. ### Claim 8 (depends on 1) The display system according to claim 1, wherein each of the first head mounted display and the second head mounted display is a portable head mounted display. ### Claim 9 (depends on 1) The display system according to claim 1, wherein the electronic device is a printer, and wherein the processor is embedded in one of the printer, a server which is independently provided on an outside of the printer, and one of first head mounted display and the second head mounted display. ### Claim 10 A display control device comprising: a memory configured to store computer-readable instructions relating to first work and second work, the first work being viewable on a first head mounted display by only a first user to conduct the first work for an electronic device, the second work being viewable on a second head mounted display by only a second user to conduct the second work for the electronic device, the first work and the second work relating to an error of the electronic device; and a processor configured to execute the computer-readable instructions such that the processor is configured to: display a first work content of the first work on the first head mounted display and the first work content of the second work on the second head mounted display; display a second work content of the first work on the first head mounted display when the processor is configured to display a work wait content of the second work on the second head mounted display; and display a third work content of the first work on the first head mounted display and the third work content of the second work on the second head mounted display after the first user completes the second work content of the first work, wherein the first work content is different from the second work content and the third work content, and the second work content is different from the third work content, the work waiting content is a notification of a waiting state for the second user, one of the first work content and the third work content includes an indication of a start time at which the first and second users start one of the first work content and the third work content at the same time, and the first, second, and third work contents relate to a solution of the error of the electronic device. ### Claim 11 A display method for causing a processor to execute computer-readable instructions stored in a memory, the display method comprising executing on the processor the step of: displaying a first work content of first work on a first head mounted display that is viewable by only a first user to conduct the first work for an electronic device and displaying the first work content of second work on a second head mounted display that is viewable by only a second user to conduct the second work for the electronic device, the first work and the second work relating to an error of the electronic device; displaying a second work content of the first work on the first head mounted display when the processor is configured to display a work wait content of the second work on the second head mounted display; and displaying a third work content of the first work on the first head mounted display and the third work content of the second work on the second head mounted display after the first user completes the second work content of the first work, wherein the first work content is different from the second work content and the third work content, and the second work content is different from the third work content, the work waiting content is a notification of a waiting state for the second user, one of the first work content and the third work content includes an indication of a start time at which the first and second users start one of the first work content and the third work content at the same time, and the first, second, and third work contents relate to a solution of the error of the electronic device. ### Claim 12 (depends on 10) The display control device according to claim 10, wherein the electronic device is a printer. ### Claim 13 (depends on 11) The display method according to claim 11, wherein the electronic device is a printer. ### Claim 14 (depends on 10) The display control device according to claim 10, wherein the indication of the start time that is displayed on each of the first head mounted display and the second head mounted display corresponds to a countdown. ### Claim 15 (depends on 11) The display method according to claim 11, wherein the indication of the start time that is displayed on each of the first head mounted display and the second head mounted display corresponds to a countdown.
