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-PRINTER 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: ePCLDemoPage2 is the printer demo page. ePCLFontList1 is the PCL typeface list. LaserJet 6P does not support continuously printing a demo page. The printer must be idle before it will print an internal page. When this object is set to a valid value and the printer is idle, the status returned is and the value returned ePrintingAnUnknownInternalPage. If the printer is not idle (whether printing an external job, printing an internal page or executing a self test), a status of status will be returned with a value of eNotPrintingAnInternalPage. Setting this object to a valid value causes the desired page to be formatted and put in the printer's print queue. While the page is being formatted a get on this object will return the value ePrintingAnUnknownInternalPage. Attempting to set this object before the page has completed being formatted will cause status to be ePrintingAnUnknownInternalPage. (The time to format an internal page is currently estimated at less than a second.) After the page is in the queue, a get on this object will return a value of eNotPrintingAnInternalPage. Setting this object to cause another page to be printed before the first page has completed results in a status of status with a value of eNotPrintingAnInternalPage. Likewise, if the SELF-TEST object is set to eNonDestructiveSelfTest and that page has not printed when this object is set to print a page, a status of status with a value of eNotPrintingAnInternalPage will be returned until the self test page has printed. The user will not be able to set eNotPrintingAnInternalPage or ePrintingAnUnknownInternalPage.
