After completing the drawing in the HaoChen CAD software, it is often necessary to print out the CAD drawings. However, sometimes the text on the drawings disappears after printing. What should be done in such cases? Let’s take a look together with the editor! This issue with the print output and preview may be caused by problems with the printing driver or the graphics. Try using the built-in DWG to PDF driver in HaoChen CAD software to view the drawing; indeed, this is the case. After printing the CAD drawing as a PDF, first check which text is printed and which is not. Then select one text element that can be printed and one that cannot be printed in the drawing, and open the property box (CTRL+1). Let’s take a look at what common attributes and what different attributes they have, as shown in the figure below. It can be seen from the attribute box that both texts are single-line texts, they belong to the same layer and have the same text style; the only difference is their width factor. In fact, it can be seen from the image that the widths of the text are different; one boundary is relatively smooth, while the other shows some jagged edges. To see more information than what is displayed in the property box, enter the LI (LIST) command to view the parameters of these two items further, as shown in the figure below. From here, it can be seen that the width factors for the two characters are 1 and 0.9 respectively; the value 0.9 is what can be printed. By changing the width factor of 1 to 0.9, these characters can be printed. But this shouldn’t be the root of the problem, and I also can’t understand why 0.9 can be printed while 1 cannot! Notice a detail in the image above: the font style of this text is simplex. The absence of ‘shx’ after the font name indicates that the operating system’s font simplex.ttf is being used, rather than the CAD font simplex.shx. Similar to CAD’s simplex.shx font, simplex also contains only single-character fonts and does not include Chinese characters. So how are those Chinese characters displayed? Enter ST to open the text style dialog box; this text style is quite strange – the font set for it is simplex, the checkbox for \"Use large font\" is grayed out, and the dropdown list under \"Font style\" on the right side is active, indicating that the system font is being used. This font does not include Chinese characters; it is almost impossible for anyone in China to set the font in this way. The Chinese characters in the image can be displayed only because the CAD software uses an automatic replacement mechanism, and they should have been replaced with Song typeface. Try selecting an SHX font similar to simplex again; that way you’ll know what it looks like when it displays properly. Select another SHX file from the font name list, then choose simplex.shx again. If you click the \"Apply\" button to use this setting and close the text style dialog box, and then enter the RE command to regenerate the graphic, you will find that those Chinese characters have turned into question marks – this is the normal appearance of Chinese characters under this text style setting, as shown in the figure below. Obviously, there is an error in the data related to the text style in this image; the style settings themselves do not allow Chinese characters to be displayed. However, CAD software’s automatic replacement feature deceived us, preventing us from realizing that it was a problem with the text style. Change the text style to a font that can display Chinese characters; for example, you can select \"Xin Songti\" directly from the font list, or check \"Use larger font\" and choose hztxt.shx as the larger font. After that, printing will work properly, with all text being printed correctly. The above are the reasons why the text on CAD drawings disappears after printing them in the HaoChen CAD software, along with the solutions.
