How to Print From Multiple Trays HP LaserJet

Printing from Multiple Trays on an HP2400 Series LaserJet

The purpose of this tech tip is to illustrate a way to print from multiple trays on an HP2400 printer from a BASIC program by sending the appropriate escape sequences to the printer.

This is very useful when you need to print different documents on the same printer and they need different paper size, type, color, letterhead, etc. As a practical example, while printing the shipping documents you might need the Shipper to print on the paper from Tray 2 and the Packing List on the paper from Tray 3 with each printer tray containing a different colored paper.

Note: the test program below contains all of the Tray Options which were copied from the HP manual which was downloaded from the HP website. You may need to change the Form Feed variable for your system.
  • DataFlo systems – Replace the FF=CHAR(12) line with these 2 lines to let DataFlo figure out what the Form Feed character is:
  • Other systems –You’ll need to define the FF variable with the Form Feed Character for your system.
    • For UniVerse, you can use:
    • For UniData, use both character 12 and 13, FF=CHAR(12)

Here's the full test program, compatible with DataFlo Version 5.4 and higher. Try this sample program on your system and once you get it working, use the code in your own programs, inserted at the appropriate points in the program when you need to switch paper trays.
** PURPOSE : Test sending escape command to printer to switch trays

* Note on Trays, 1 is the Manual feed, 2 & 3 are the storage ones.
* Here's the command: Ec&l#H
* Here are the Tray Options (#):
* 0 = Prints or ejects current page
* 1 = Tray 2
* 2 = Manual feed, paper
* 3 = Manual feed, envelope
* 4 = Tray 1
* 5 = Tray 3
* 6 = Optional envelop feeder
* 7 = Auto select
* 8 = Tray 4
* 20 to 69 = external trays
* So, to print from Tray 2 replace the # in Ec&l#H with a 1
* giving us Ec&l1H then convert that to hex for printing, 1B266C3148
FF = CHAR(12) ;* Char 12 works for UniVerse (Pick flavor)
TRAY2 = "1B266C3148"
TRAY3 = "1B266C3548"
PRINT "Printing from Tray 2"
PRINT "Printed from Tray 3"
* Switch back to Tray 2 as we are assuming that is the default tray
