Chapter 5 Feeding & Printing Commands
2. Label Printing
1. Paper Feed,
cont'd.
If the
FORMFEED
command is issued without any specification of
the feed length, a complete blank label (or the equivalent) will be
fed out. By specifying a positive or negative value in the
FORMFEED
command, the global Start Adjust and Stop Adjust setup can be
substituted or supplemented for individual layouts or labels.
It is important whether the
FORMFEED
command is executed be-
fore or after the
PRINTFEED
command:
•
FORMFEED
before
PRINTFEED
corresponds to Start Adjust.
•
FORMFEED
after
PRINTFEED
corresponds to Stop Adjust.
The relationship between paper and printhead when printing starts
decides all positioning along the Y-axis, i.e. along the paper web.
Printing Commands
When a
PRINTFEED
command is issued, the software processes
all previously entered text fields, bar code fields, image fields, box
fields and line fields into a bitmap pattern. The bitmap pattern con-
trols the heating of the printhead dots as the paper is fed past them.
Each
PRINTFEED
command produces one single copy or, option-
ally, a batch of labels, tickets, tags or pieces of strip.
PRINTFEED | PF [<batch size>]
<batch size>
specifies the number of copies to be printed.
Default:
1
The execution of a
PRINTFEED
command resets the following
commands to their respective default values:
ALIGN
BARFONT
BARFONTSIZE
BARFONTSLANT
BARFONT ON/OFF BARFONTD
BARFONTDSIZE
BARFONTDSLANT
BARHEIGHT
BARMAG
BARRATIO
BARSET
BARTYPE
DIR
FONT
FONTSIZE
FONTSLANT
FONTD
FONTDSIZE
FONTDSLANT
INVIMAGE
MAG
PRPOS
This reset only affects commands executed after
PRINTFEED
, not
commands that have already been executed, which makes batch
printing possible.
