Command Line printing to a specific printer tray

[Txt8888]

hello all,

I am new here and not quite sure if this same question was asked previous but I could not find the similar thread here.

I am pretty much spend most of my time on the "Terminal" on Mac. I want to find out if there is a way to use lp (or lpr) to print a file to my printer but with option to specify which tray (my printer has 2 trays. Manual, and the regular tray) the paper is from.

here are some of the info:

1/

lpoptions -l

ColorModel/Color Mode: *Gray
cupsPrintQuality/Quality: *Normal
Duplex/2-Sided Printing: *None DuplexNoTumble DuplexTumble
PageSize/Media Size: 3x5 A4 A5 A6 B5 Env10 EnvC5 EnvChou3 EnvDL EnvMonarch EnvYou4 Executive FanFoldGermanLegal ISOB5 ISOB6 Legal *Letter Postcard Custom.WIDTHxHEIGHT
MediaType/MediaType: stationery stationery-lightweight stationery-heavyweight stationery-bond envelope labels *any
InputSlot/Media Source: auto by-pass-tray manual tray-1

2/ I set the Media Source by:

lpoption -o media=manual

and the result with

lpoptions -l

is:

ColorModel/Color Mode: *Gray
cupsPrintQuality/Quality: *Normal
Duplex/2-Sided Printing: *None DuplexNoTumble DuplexTumble
PageSize/Media Size: 3x5 A4 A5 A6 B5 Env10 EnvC5 EnvChou3 EnvDL EnvMonarch EnvYou4 Executive FanFoldGermanLegal ISOB5 ISOB6 Legal *Letter Postcard Custom.WIDTHxHEIGHT
MediaType/MediaType: stationery stationery-lightweight stationery-heavyweight stationery-bond envelope labels *any
InputSlot/Media Source: auto by-pass-tray *manual tray-1

3/ but when I use

lp myfile.pdf

, it prints without using the paper at the manual paper feed.

4/ I try

lp -o media=manual myfile.pdf

and result is the same thing, not print to the paper from the manaul feed.

Did I use the wrong option(s) or something else?

Any suggestion will greatly appreciate it. Thanks
