APPENDIX E – Multi-Part Forms Programming
Multi-Part Forms Programming
Laser Printers offer many advantages but there is one deficiency compared to impact printers, the inability to print
multi-part forms.
The use of multi-part forms reduces printing time and permits the use of different paper for distribution and filing
purposes. Laser printers usually have only one or two cassettes and therefore it is not possible to provide a
simulation of multi-part forms because not enough different paper types are available.
Also, laser printers with a copy command sent to the printer will not allow the switching of the paper source for
printing and produce identical copies. As a result, the benefits of multi-part forms are not available.
Now TowerFeed in combination with your laser printer offers an effective way to gain the benefits of multi-part
forms printing.
Example:
A one page document has to be printed four times, e.g., a master and three copies, each of which has to be on a
different paper type from a different TowerFeed drawer.
The following commands achieve this task:
Start of document: Reset printer ESC E
Specify number of copies ESC&l4X
Feed sequence commands ESC~I11z12z13z14Z
The Document
Print data
End of document
Specify/(Reset) number of copies ESC&l1X
Reset printer ESC E
Explanation:
• Printer and TowerFeed are reset at the start of the document.
• The number of copies is then set to the desired 4 copies.
• In the feed commands, the command strings for all sheets are strung together as a ”chain”.
The commands are for direct addressing:
ESC~I11z Feed from drawer I
ESC~I12z Feed from drawer 2
ESC~I13z Feed from drawer 3
ESC~I14z Feed from drawer 4
After the document is printed, TowerFeed and printer are to be reset to the standard settings.
