Description: Writing this object to a value other than eNotPrintingAnInternalPage causes the device to attempt to print an internally generated page. Reading this object provides an indication what internally generated page is currently being printed, if any. The actual page is device specific. Some devices may support continuously printing an internally generated page. Setting this object to eNotPrintingAnInternalPage terminates continuously printing internally generated pages. An internally generated page may not be allowed to be printed at any arbitrary time; under what conditions it will succeed or fail is device specific. If the device supports the requested page, but can not start printing the page when requested, the device will respond with . RECOMMENDATION: If the device is ready (i.e. the NOT- READY object does not contain any items, except maybe being off-line) and is idle (i.e. the NOT-IDLE object does not contain any items), this request should always succeed. This provides a mechanism for driver writers to always determine if the action will succeed or not. Additional information: ePCLDemoPage1-ConfigurationPage (the PCL test page) is not supported. The PCL configuration page is generated by using the SELF-TEST OID above. ePCLDemoPage2 is the PCL Demo page, and ePCLFontList1 is the PCL typeface list. ePostScriptDemoPage1-ConfigurationPage is the PostScript configuration page. The ePostScriptDemoPage2 is the same PostScript demo page that can be printed via the control panel. ePostScriptFontList1 is the PostScript typeface list. LaserJet 4V does not support continuously printing a demo page. A page is not allowed at any arbitrary time. LaserJet 4V must be ready (except for being offline), offline, and idle before a page can be printed. If the requested page cannot start printing when requested, LaserJet 4V will respond with status. IfLaserJet 4V is ready (i.e. the NOT-READY object does not contain any items, except being off-line). offline, and is idle (i.e. the NOT-IDLE object does not contain any items), this request should always succeed. This provides a mechanism for driver writers to always determine if the action will succeed or not. When PostScript option is not installed, LaserJet 4V will respond with status for any attempt to write this object to ePostScriptDemoPage1-ConfigurationPage, ePostScriptDemoPage2, and ePostScriptFontList1.
