new
Constructs a tags object.
tag_allowed
Returns true if the given tag is defined.
parse( $element )
Method for recursive parsing of tags.
simple_switch
Helper method for simple 0/1 switches.
include_global_options
Helper method to add global options to object options.
_0
Prints plain text and strips out leading and trailing whitespaces.
_text
Prints plain text. To activate automatic word wrapping, you can use the attribute wordwrap to set the word wrap width (use the maximum number of characters per line. When wordwrap is active, you can set the bodystart parameter to define the characters that should be printed at the beginning of each line (except the first one). You can use this to set some indentation.
_bold
Sets text to be printed bold.
_doubleStrike
Sets text to be printed double striked.
_invert
Sets text to be printed inverted.
_underline
Sets text to be printed underlined.
_upsideDown
Sets Upside Down Printing.
_color
Use this tag to use the second color (if support by your printer).
_rot90
Use this tag to use the second color (if support by your printer).
_qr
Prints a QR code. Possible attributes:
ecc
version
moduleSize
_barcode
Prints a barcode to the printer. See Printer::ESCPOS::Manual for a list of possible options. The barcode content should be set as the tag content like <barcode>content</barcode>. All other options must be set as attributes.
_utf8ImagedText
Can print text with special styling. Use the parameters allowed in Printer::ESCPOS's method utf8ImagedText as attributes for the utf8ImagedText tag. In addition you can use the attribute wordwrap to set the word wrap width. By now, it is only possible to set the maximum number of characters per line. Later we should try to implement a wrapping based in the maximum pixel width of a line. When wordwrap is active, you can set the bodystart parameter to define the characters that should be printed at the beginning of each line (except the first one). You can use this to set some indentation.
_lf
Moves to the next line. If the lines attribute is given, move that number of lines.
_tab
Moves the cursor to next horizontal tab position.
_image
Print image from named file.
_printAreaWidth
Sets the print area width.
_set
Sets global variables: paperWidth, wordwrap, fontFamily, fontSize, fontStyle, lineHeight, printAreaWidth
_unset
Resets global variables to standard values: paperWidth, wordwrap, fontFamily, fontSize, fontStyle, lineHeight, printAreaWidth Syntax: <unset fontStyle="" />
_hr
Adds a horizontal line. Use the thickness attribute to set the line's thickness. Defaults to 2.
_tabpositions
Sets horizontal tab positions for tab stops. Syntax for XML is the following:
<tabpositions>
<tabposition>5</tabposition>
<tabposition>9</tabposition>
<tabposition>13</tabposition>
</tabpositions>_repeat
Repeats the content n times. Syntax:
<repeat times="3">
[tags to repeat]
</repeat>_justify
Set justification to left, right or center. Syntax for XML is the following: <justify align="right">text</justify>
_table
Prints text in table format. By now, this tool is only helpful for monospaced fonts. Possible cell parameters are width (only in pattern row), colspan and align (right, left, center). Possible line parameters are fontStyle and align. Possible table parameters are fontSize, wordwrap, lineHeight, paperWidth, separator, leftBorder, rightBorder and fontStyle.
check_table_validity
Checks validity of table tags and attributes. (Helper for table tag.)
get_rows_and_cells
Returns table rows and cells (options and content). (Helper for table tag.)
calculate_table_column_widths
Calculates the width for each table column. (Helper for table tag.)
break_table_lines
Breaks cell content if it doesn't fit column width and returns table rows and cells (options and content). (Helper for table tag.)
