Module not using certain tokens on print page

This may not be an issue with this module, but I'm trying to find out. Here's my somewhat complex setup:

I have a node creation form with a number of fields that take user input. This input is concatenated into a string of values by another field using tokens to get their replacement values. This field takes tokens using thew Token Filter module. This field is also a PHP text input type & includes some PHP to conditionally select a token from one of two select list fields.

[node:created:custom:YmdHi] [node:author:uid] <?php
if ($node = menu_get_object()) { 
$field1 = field_get_items('node', $node, 'field_gaylord_location_boz001'); 
$field2 = field_get_items('node', $node, 'field_gaylord_location_bil001'); 
if (!empty($field1)) { 
print '[node:field_gaylord_location_boz001]'; 
} 
if (!empty($field2)) { 
print '[node:field_gaylord_location_bil001]'; 
}
} 
?> [node:field-gaylord-weight] [node:field_gaylord_serial]

Only one of these select list fields is presented to the user based on UID. So on submission one field will be left blank & the other will have a value. The one with the value will be included in the concatenated string of values.

Then this string is fed into a field for the Barcode module using its own token. On form submission, the concatenated string is encoded into a barcode.

All functioning great. However, when I try to use the Print module to print the node, the barcode on the print page is different; missing the replacement values of the token from the select list.

Any idea why the print page can't see this token value while the node page can?
