I am using ZPL for the first time to generate shipping labels. I am using a ruby-on-rails gem https://github.com/rjocoleman/labelary to ultimately turn the ZPL sting into a pdf. I want to create multiple pages, incrementing a variable for each page using a loop until enough pages have been created. Say the ZPL looks like this:
^XA
^FX Top section with company logo, name and address.
^CF0,60
^FO50,50^GB100,100,100^FS
^FO75,75^FR^GB100,100,100^FS
^FO88,88^GB50,50,50^FS
^FO220,50^FDInternational Shipping, Inc.^FS
^CF0,40
^FO220,100^FD1000 Shipping Lane^FS
^FO220,135^FDShelbyville TN 38102^FS
^FO220,170^FDUnited States (USA)^FS
^FO50,250^GB700,1,3^FS
^FX Second section with recipient address and permit information.
^CFA,30
^FO50,300^FDJohn Doe^FS
^FO50,340^FD100 Main Street^FS
^FO50,380^FDSpringfield TN 39021^FS
^FO50,420^FDUnited States (USA)^FS
^CFA,15
^FO600,300^GB150,150,3^FS
^FO638,340^FDPermit^FS
^FO638,390^FD123456^FS
^FO50,500^GB700,1,3^FS
^FX Third section with barcode.
^BY5,2,270
^FO175,550^BC^FD1234567890^FS
^FX Fourth section (the two boxes on the bottom).
^FO50,900^GB700,250,3^FS
^FO400,900^GB1,250,3^FS
^CF0,40
^FO100,960^FDShipping Ctr. X34B-1^FS
^FO100,1010^FDREF1 F00B47^FS
^FO100,1060^FDREF2 BL4H8^FS
^CF0,190
^FO485,965^FDCA^FS
^XZ
How can I add a page break to the end of the ZPL string, so the loop can create a new identical page after the first one (all in a single zpl string)?
Thanks in advance
If your pages are truly identical, you could just use the ^PQ command to set the number of copies you want to print (e.g. ^PQ3 to print three copies). This command must appear before the ^XZ command.
However if your pages aren't identical (maybe you have a sequence number or something), just start a new format by using a new ^XA command after your first page is done.
