Print some pages in duplex plus add T&Cs on them

Printing duplex is a little tricky regarding on where the duplex command needs to be added. A more detailed description can be found here.

More examples can be found here:

Print on the first page a full letter head and only the logo on the following pages. Adding FormFeeds and insert pages.
Insert Terms & Conditions on page 1 or at the end on last page
T&C on all back pages; Extended: front page with a letter head, remaining pages with just the logo
Print job duplex, add on all back pages the terms & conditions, on first page the letter head, on remaining front pages the logo
Print Job Duplex, but beginning with a specific page change to simplex
Print simplex and duplex jobs on preprinted/prepunched paper

Here a more tricky solution: ELP is asked to print X copies, but in the non collated order. Example for 3 copies: Page 111 222 333 444 etc...

ELP_Command=R3;

This one is now straight forward, so you can use the C#[:#] commands to define the copy number and the page to do something.

But the client wanted to have on the first page of copy 1 and 2 the T&Cs added on the back page, and all remaining pages printed simplex, but then all stapled together.

Inserting Form Feeds on the first page and adding the T&Cs is here not an option, as then the T&Cs will be printed in 3 copies on pages 4 to 6.

The solution to this needs an additional macro which is generated the best like this:

Copy the file 100.mac from the folder c:\ProgramData\WELP to - for example - the file 28222.mac in the same folder
If not done before, install notepad++ or any other ASCII Editor which does NOT change a files (Notepad or MS Word or WordPad unfortunately do that)
Load that file 28222.mac into that Editor and change the content to just one Sequence: ESC&a2G
No new line etc. Just one lien with that content.
Store the file back and leave the editor

Now add the ELP_Command to your rule, here e.g. into the rule Global:

[Global]

ELP_Command=R3;C1:1S1F500F28222F501;C1S0F502;C2:1S1F500F101F28222F501;C2S0F101F502;C3S0FF102502;T200;

; R3; generate 3 copies in order 111 222 333 ....

; C1:1 define the first page of the first copy
; S1 print duplex long side

; F500 Overlay the complete letter head form

; F28222 This form does send the above defined print command (escape sequence) to the device, which is:
; Go to back page. That command is NOT recognized by ELP for changing the page. So it is not counted!

; F501 Being now on the back page, print the T&C form.
; C1 definition for all remaining pages of copy 1

;      S0     print them in simplex
;      F502; print the Company logo on all remaining pages of copy 1.
; C2:1 and C2 command is the same as above, in addition the watermark book keeping is printed on any front page
; C3   is the same as C2, but even the first page is simplexed and on all pages appear a watermark "Copy".
; Txxx; is the stapling command. All pages will be stapled together

Finally if the print job is NOT surrounded by an UEL command, please add also the ET; command at the end of the ELP_Command.
