To combine printer escape commands (not including PJL commands): The first two characters after the MUST be the same. All alpha characters MUST be lowercase, except the final terminating character. The commands are read left to right. Combine them in the order you wish them executed.For example, print 5 copies (&l5X) and use letter size (&l2A) is combined as: &l5x2A In case of duplicate commands, the last one requested takes precedence. The @PJL SET COPIES takes precedence over the PCL Escape Command ( & l int X>) to determine number ofcopies. In general, a PJL command takes precedence over a PCL command. When printing a job with an odd number of pages and duplex front and back imaged covers, the printer always printson both sides of the front and back covers. The remaining pages are printed on the document body media type andcolor with a blank page inserted to allow an image on both sides of the back cover. When using the Blank Front or the Blank Front & Back Cover command, the Cover Media Size command is optional. Ifthe cover size command is not in the PDL, the printer assumes the cover media size is the same as the documentbody. Use one of the following methods to specify media selection: Describe the media attributes with size, color, and type and allow the device to select the matching source tray. Ifthe media description method is used, leave source tray selection out of the request or set to Auto. If not, the trayselection defeats the auto tray selection capabilities of the device. Indicate the tray to supply media. If the source tray method is used, the system automatically defaults papertype to the defined SYSTEM DEFAULT unless specified otherwise. This prevents inadvertent use of special papertypes. To override, include a paper type specification of UNSPECIFIED in the job.DSC/PS Dependencies/Caveats All %% commands (DSC comments) must be in the first 64KB of the job. WorkCentres supports PostScript resolutions up to and including 1800 x 1800. Some PostScript jobs may not print ifthe high resolution is indicated. If this occurs, print the same job at a lower resolution. The following media sizes do not print duplex and do not support staple commands: A6, B6, 5 x 7" Postcard (4.5 x 6"),envelopes and any custom sized media where the page width is less than 5.5". A request to duplex or staple thesemedia sizes is ignored. Jobs that indicate Transparencies, Labels, Envelopes or Tab-Stock do not support duplex commands. The duplex printrequest is ignored when any of these media types are used. When printing an odd number of pages in a document with duplex front and back imaged covers, the printer alwaysprints on both sides of the front and back covers. The remaining pages print on the document body media type andcolor with a blank page inserted to allow an image on both sides of the back cover. When using the Blank Front or the Blank Front and Back Cover command, the Cover Media Size command is optional.If the Cover Media Size command is not in the PDL, the printer assumes the cover media size as that of the documentbody. Use one of the following methods to specify media selection: Describing the media attributes with size, color, and type and allowing the device to select the matching sourcetray. If the media description method is used, leave source tray selection out of the request or specifically set toAuto. Otherwise, the tray selection defeats the auto tray selection capabilities of the device. Specifically indicate the tray to feed from. If the source tray method is used, the system automatically defaultspaper type to the defined SYSTEM DEFAULT unless specified otherwise. This occurs to prevent inadvertent use ofspecial paper types. To override, include a paper type specification of UNSPECIFIED in the job.
