Purge Print Jobs Fails to Clear Printer Buffer

• Microsoft Windows 95

SUMMARY

Windows 95 allows you to remove all print jobs from a printer by double- clicking your printer and then clicking the Purge Print Jobs command on the Printer menu. However, if a document containing graphics is currently printing when you click the Purge Print Jobs command, a portion of the purged document prints on the first page of the next print job. The second, and subsequent pages print correctly. On some printers, it is possible to clear the graphics by forcing a page feed. In most cases though, you must reprint the first page of the document to get the correct output.

MORE INFORMATION

Some printers send raster data or graphic images using a command that indicates how many bytes of raster data will be sent followed by the actual image in bytes. For example, sending X bytes of raster data, followed by the X bytes.

When a print job is purged, the spooler stops sending data and makes a request for the printer driver to send a reset command to the printer.

If the data stream is in the middle of transferring raster data, the reset command can be interpreted as more raster data in which case the printer will continue printing the image. If the data stream is not in the middle of transferring raster data, the printer will stop printing where the reset command was issued.
