Abstract
The invention provides a printing medium calibration control method which comprises the following steps of: receiving a printing task; detecting the distance between two adjacent marks of a printing medium, i.e. a first actual ticket surface height; when the marks are not detected or a bottom ticket surface height is not equal to the first actual ticket surface height, starting automatic calibration; and executing the printing task. In the invention, only when the marks of the printing medium are not detected or the bottom ticket surface height is not equal to the first actual ticket surface height, the automatic calibration is started, so that the bottom ticket surface height is consistent with the actual ticket surface height, which avoids the unnecessary automatic calibration caused by wrong user setting, lowers the requirement of the prior art for a user to know a printer principle, improves the work efficiency and the easy use property of a printer, and solves the problem of lower work efficiency caused by that if the page height set by the user is inconsistent with the bottom ticket surface height in the prior art, even though a medium type is not replaced, an automatic calibration function can also be executed when the printer is electrified every time.
Description
Technical field
The present invention relates to printer field, in particular to a kind of printing medium calibration control method.
Background technology
The common usage flag paper of bar code printing is as print media, as black millimeter paper or label paper, for printing the nominal value of regular length.Fig. 1 shows the black millimeter paper schematic diagram of correlation technique; Fig. 2 shows the label paper schematic diagram of correlation technique.For convenience, conventionally the distance between two mark M is called to ticket surface height H.Existing mark sheet printer, by being set, automatic calibration function detects ticket surface height, its general principle is: at printer paper-feeding channel setting sensor, utilize sensor voltage to change, detect medium mark, and be the nonvolatile memory that ticket surface height stores printer into by the distance between adjacent two marks that detect.
For convenience of description, printer is detected and stored into the ticket surface height of nonvolatile memory referred to as bottom ticket surface height, print media ticket surface height is called for short to actual ticket surface height.Owing to only having in the time that actual ticket surface height is consistent with bottom ticket surface height, printer could utilize sensor to determine the print position of every nominal value, therefore, in the time changing dissimilar print media, need to start automatic calibration function, upgrade the ticket surface height of storage in printer nonvolatile memory.Existing printer, whether consistent with bottom ticket surface height by judging the page height of user's setting, judge whether medium is changed.When user arranges ticket surface height and bottom ticket surface height when inconsistent, start automatic calibration function.
Realizing in process of the present invention, inventor finds that in prior art, at least there are the following problems: when user arranges page height and bottom ticket surface height is inconsistent, even without changing print media type, printer powers at every turn and also can carry out automatic calibration function, causes operating efficiency lower.
Summary of the invention
The present invention aims to provide a kind of printing medium calibration control method, can solve in prior art when user arranges page height and bottom ticket surface height is inconsistent, even without changing print media type, printer powers at every turn and also can carry out automatic calibration function, causes the problem that operating efficiency is lower.
In an embodiment of the present invention, provide a kind of printing medium calibration control method, comprised the following steps: accept print out task; Distance between the two adjacent marks of detection print media, i.e. the first actual ticket surface height; In the time can't detect mark or bottom ticket surface height and be not equal to the first actual ticket surface height, carry out automatic calibration; Carry out print out task.
Above-described embodiment is by judging whether bottom ticket surface height equals the first actual ticket surface height, judge whether print media changes, only can't detect under the mark of print media or condition that actual ticket surface height changes and just start printing medium calibration at printer, avoid, because of user, the unnecessary automatic calibration that mistake causes is set, reduce prior art and user understood to the requirement of printing principle, operating efficiency and the ease for use of printer are improved, if overcome in prior art, user arranges page height and bottom ticket surface height is inconsistent, even without changing media type, printer powers at every turn and also can carry out automatic calibration function, cause the problem that operating efficiency is lower.

Step S108, carries out print out task.
Above-described embodiment is by judging whether bottom ticket surface height equals the first actual ticket surface height, judge whether print media changes, only can't detect under the mark of print media or condition that actual ticket surface height changes and just start printing medium calibration at printer, avoid, because of user, the unnecessary automatic calibration that mistake causes is set, reduce prior art and user understood to the requirement of printing principle, operating efficiency and the ease for use of printer are improved, if overcome in prior art, user arranges page height and bottom ticket surface height is inconsistent, even without changing media type, printer powers at every turn and also can carry out automatic calibration function, cause the problem that operating efficiency is lower.
Meanwhile, in prior art, as user, that page height is set is consistent with bottom ticket surface height, but in fact variation has occurred print media ticket surface height, can cause to print to locate inaccurately, causes print What position confusion; And above-described embodiment is accepted after print out task at printer, by judging whether to detect whether the mark of print media or bottom ticket surface height equal the first actual ticket surface height, judge whether print media changes, in the time can't detect the nominal value mark of print media or bottom ticket surface height and be not equal to the first actual ticket surface height, show that change has occurred print media, now start automatic calibration, make bottom ticket surface height consistent with actual ticket surface height, carry out again print out task, thereby can accurately print at correct print position.
Fig. 4 shows according to the printing medium calibration control method flow chart of Fig. 3 preferred embodiment, comprises the following steps:
Step S202, accepts print out task;
Step S204, detects the first actual ticket surface height;
Step S206, judges whether to detect mark, if so, enters step S208, otherwise, enter step S210;
Step S208, judges whether bottom ticket surface height equals the first actual ticket surface height, in the time that bottom ticket surface height is not equal to the first actual ticket surface height, enters step S210, otherwise, enter step S212;
Step S210, carries out automatic calibration; And
Step S212, carries out print out task.
In the time that bottom ticket surface height equals the first actual ticket surface height, illustrate that print media does not change, now, without calibration, can directly carry out print out task.Like this, save unnecessary calibration steps, improved the operating efficiency of printer.
Preferably, in above-mentioned printing medium calibration control method, further comprising the steps of before detecting the first ticket surface height: the state that detects printer.The present embodiment judges by detecting the state of printer whether print media replacing has occurred, thereby provides judgment condition for whether detecting the first ticket surface height.
