All alpha characters MUST be lowercase, except the final terminating character. The commands are read left to right. Combine commands in the order you wish themto execute.For example, combine print 5 copies (&l5X) and use letter size (&l2A) as&l5x2A.• In case of duplicate commands, the last one requested takes precedence.• The @PJL SET COPIES takes precedence over the PCL Escape Command (<ESC> &l int X>) to set copies. In general, a PJL command takes precedence over a PCLcommand.• Do not duplex and/or staple any job with these media sizes: A6, B6, 5 x 7" Postcard (4.5x 6"), envelopes and any custom sized media where the page width is less than 5.5". Arequest to duplex or staple these media sizes is ignored.• Do not duplex any job with transparencies, labels, envelopes or tab-stock The duplex printrequest is ignored if you use any of these media types.• To use the duplex front and back imaged covers option most effectively, rememberthese items when you prepare the contents of the print file:− The Document Centre uses the contents of the first two and last two pages of the fileas the front cover, inside front cover, back cover, and inside back cover.− The remaining pages print on the document body media type and color.− If a print file contains an odd number of pages, the Document Centre leaves the lastbody page (that is, the page adjacent to the inside back cover) blank.• When using the Blank Front or the Blank Front & Back Cover command the Cover MediaSize command is optional. If the cover size command is not in the PDL, the printerassigns the media size of the document body to the cover.• Use one of the methods described in the following list to specify media selection: Describe the media attributes with size, color, and type and allow the device to selectthe correct source tray. If you describe the media leave source tray information out ofthe request or set to Auto. Otherwise, the tray selection defeats the auto trayselection capabilities of the device. Indicate the media feed tray to use. In doing so, you allow the device to select mediafeed trays based on paper type defined by SYSTEM DEFAULT unless specifiedotherwise. This method prevents inadvertent use of special paper types. To overridea paper type definition, include a paper type specification of UNSPECIFIED in thejob.
