On some printers, if
the PAPERSIZE= option is also specified, it overrides the setting
on the PAPERSOURCE= option.
For PostScript printers,
a tray number, such as PAPERSOURCE='tray3', must correspond to an
InputSlot value in the PPD file.
For PCL printers, consult
the printer's documentation for valid tray values. If a numeric value
exceeds the maximum tray value allowed for the printer, a warning
message is issued . For string values, the string is checked against
a list of strings that are valid for the driver:
-
-
'HCI' or 'HCI
n', where
n is a number from 2 to 21
-
-
-
'TRAY
n', where
n is 1, 2, or 3.
If the string is not valid for the driver, a warning
message is issued.
